Description

TITLE CROSSLINKED ALPHA-GLUCAN DERIVATIVES This application claims the benefit of U.S. Provisional Appl. Nos.63/587,005 (filed September 29, 2023) and 63/598,263 (filed November 13, 2023), which are each incorporated herein by reference in their entirety. FIELD The present disclosure is in the field of polysaccharide derivatives. For example, the disclosure pertains to crosslinked derivatized alpha-glucans, and use of this material in various applications. BACKGROUND Multifunctional detergent compositions have been produced that provide cleaning, water-softening, and rinsing benefits. To illustrate, detergent formulations for automatic dishwashers and other appliances have been designed to function under hardwater conditions. Hardwater cations such as Ca²⁺ and Mg²⁺ can crystalize with carbonate and form insoluble salts that form deposits (also known as scaling) on surfaces such as dishware or appliance internal components (e.g., pipes, sprayers). Hardwater cations also play a role in soap scum formation. Bio-based ingredients such as sodium citrate, methylglycinediacetic acid trisodium salt (MGDA), and L-glutamic acid-N,N-diacetic acid (GLDA) can help prevent these unwanted deposits by sequestering hardwater cations and keeping them in solution. However, none of these ingredients are sufficient at preventing hardwater surface deposits after repetitive washing steps. Inhibition of hardwater deposit formation has more successfully been addressed by incorporating completely synthetic polymers (often 100% petroleum- based) such as polyacrylates (e.g., sulfonated polyacrylates) or diphosphonates (e.g., 1- hydroxyethylidene-1,1-diphosphonic acid [HEDP]) in detergent compositions. These ingredients are non-renewable and not readily biodegradable; due to such environmental concerns, these and related ingredients are the subject of increasing governmental regulation. Several detergent products have been developed that comprise one or more environmentally friendly components, but these products often fail to deliver acceptable cleaning performance to consumers (e.g., the aforementioned bio-based agents). Thus, there remains a need for cleaning composition ingredients that are renewable and/or biodegradable, and that provide cleaning performance that is equal to, or better than, the performance of products with synthetic components. Polysaccharide derivatives and detergent compositions comprising one or more of these polysaccharide derivatives, for example, are disclosed herein that address this need. SUMMARY In one embodiment, the present disclosure concerns a composition/product comprising a crosslinked alpha-glucan derivative, wherein the crosslinked alpha-glucan derivative is produced by contacting ethylene glycol diglycidyl ether (EGDE) with a first alpha-glucan derivative, thereby crosslinking the first alpha-glucan derivative, wherein the ratio of the EGDE to the first alpha-glucan derivative is about 0.03 to 0.07 mole EGDE to about 1 mole first alpha-glucan derivative. In another embodiment, the present disclosure concerns a method of washing or treating a hard surface, the method comprising: (a) contacting the hard surface with a washing/treating composition that comprises a crosslinked alpha-glucan derivative as presently disclosed, and (b) removing all of, or a portion of, the washing/treating composition from the hard surface; thereby washing or treating the hard surface, wherein the washed/treated hard surface has reduced filming, spotting, haze, or other deposition, optionally wherein the hard surface is that of glass, plastic, ceramic, porcelain, metal, or stone. In another embodiment, the present disclosure concerns a method of producing a crosslinked alpha-glucan derivative as presently disclosed, the method comprising: (a) contacting EGDE with a first alpha-glucan derivative (the first alpha-glucan derivative typically has already been derivatized herein, such as by etherification, sulfonation, or oxidation), thereby crosslinking the first alpha-glucan derivative, wherein the ratio of the EGDE to the first alpha-glucan derivative is about 0.03 to 0.07 mole EGDE to about 1 mole first alpha-glucan derivative, and (b) optionally isolating the crosslinked alpha- glucan derivative produced in step (a).

Unless otherwise disclosed, the terms “a” and “an” as used herein are intended to encompass one or more (i.e., at least one) of a referenced feature. Where present, all ranges are inclusive and combinable, except as otherwise noted. For example, when a range of “1 to 5” (i.e., 1-5) is recited, the recited range should be construed as including ranges “1 to 4”, “1 to 3”, “1-2”, “1-2 & 4-5”, “1-3 & 5”, and the like. The numerical values of the various ranges in the present disclosure, unless expressly indicated otherwise, are stated as approximations as though the minimum and maximum values within the stated ranges were both proceeded by the word “about”. In this manner, slight variations above and below the stated ranges can typically be used to achieve substantially the same results as values within the ranges. Also, the disclosure of these ranges is intended as a continuous range including each and every value between the minimum and maximum values. It is intended that every maximum numerical limitation given throughout this specification includes every lower numerical limitation, as if such lower numerical limitations were expressly written herein. Every minimum numerical limitation given throughout this specification will include every higher numerical limitation, as if such higher numerical limitations were expressly written herein. Every numerical range given throughout this specification will include every narrower numerical range that falls within such broader numerical range, as if such narrower numerical ranges were all expressly written herein. It is to be appreciated that certain features of the present disclosure, which are, for clarity, described above and below in the context of aspects/embodiments, may also be provided in combination in a single element. Conversely, various features of the disclosure that are, for brevity, described in the context of a single aspect/embodiment, can also be provided separately or in any sub-combination. The term “polysaccharide” (or “glycan”) means a polymeric carbohydrate molecule composed of long chains of monosaccharide units bound together by glycosidic linkages and on hydrolysis gives the polysaccharide’s constituent monosaccharides and/or oligosaccharides. A polysaccharide herein can be linear or branched, and/or can be a homopolysaccharide (comprised of only one type of constituent monosaccharide) or heteropolysaccharide (comprised of two or more different constituent monosaccharides). Examples of polysaccharides herein include alpha-glucan (polyglucose). A “glucan” herein is a type of polysaccharide that is a polymer of glucose (polyglucose). A glucan can be comprised of, for example, about, or at least about, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% by weight glucose monomeric units. Examples of glucans herein are alpha-glucan and beta-glucan. The terms “alpha-glucan”, “alpha-glucan polymer” and the like are used interchangeably herein. An alpha-glucan is a polymer comprising glucose monomeric units linked together by alpha-glycosidic linkages. In typical aspects, the glycosidic linkages of an alpha-glucan herein are about, or at least about, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% alpha-glycosidic linkages. Examples of alpha-glucan polymers herein include alpha-1,3-glucan, alpha-1,4-glucan, and alpha-1,6-glucan. The term “saccharide” and other like terms herein refer to monosaccharides and/or disaccharides/oligosaccharides, unless otherwise noted. A “disaccharide” herein refers to a carbohydrate having two monosaccharides joined by a glycosidic linkage. An “oligosaccharide” herein can refer to a carbohydrate having 3 to 15 monosaccharides, for example, joined by glycosidic linkages. An oligosaccharide can also be referred to as an “oligomer”. Monosaccharides (e.g., glucose and/or fructose) comprised within disaccharides/oligosaccharides can be referred to as “monomeric units”, “monosaccharide units”, or other like terms. The terms “alpha-1,3-glucan”, “poly alpha-1,3-glucan”, “alpha-1,3-glucan polymer” and the like are used interchangeably herein. Alpha-1,3-glucan is an alpha- glucan comprising glucose monomeric units linked together by glycosidic linkages, wherein at least about 50% of the glycosidic linkages are alpha-1,3. Alpha-1,3-glucan in some aspects comprises about, or at least about, 90%, 95%, or 100% alpha-1,3 glycosidic linkages. Most or all of the other linkages, if present, in alpha-1,3-glucan herein typically are alpha-1,6, though some linkages may also be alpha-1,2 and/or alpha-1,4. Alpha-1,3-glucan herein is typically water-insoluble. The terms “alpha-1,6-glucan”, “poly alpha-1,6-glucan”, “alpha-1,6-glucan polymer”, “dextran”, and the like herein refer to a water-soluble alpha-glucan comprising glucose monomeric units linked together by glycosidic linkages, wherein at least about 40% of the glycosidic linkages are alpha-1,6. Alpha-1,6-glucan in some aspects comprises about, or at least about, 90%, 95%, or 100% alpha-1,6 glycosidic linkages. Other linkages that can optionally be present in alpha-1,6-glucan include alpha-1,2, alpha-1,3, and/or alpha-1,4 linkages. An “alpha-1,2 branch” (and like terms) as referred to herein typically comprises a glucose that is alpha-1,2-linked to a dextran backbone; thus, an alpha-1,2 branch herein can also be referred to as an alpha-1,2,6 linkage. An alpha-1,2 branch herein typically has one glucose group (can optionally be referred to as a pendant glucose). An “alpha-1,3 branch” (and like terms) as referred to herein typically comprises a glucose that is alpha-1,3-linked to a dextran backbone; thus, an alpha-1,3 branch herein can also be referred to as an alpha-1,3,6 linkage. An alpha-1,3 branch herein typically has one glucose group (can optionally be referred to as a pendant glucose). The percent branching in an alpha-glucan herein refers to that percentage of all the linkages in the alpha-glucan that represent branch points. For example, the percent of alpha-1,2 branching in an alpha-glucan herein refers to that percentage of all the linkages in the glucan that represent alpha-1,2 branch points. Except as otherwise noted, linkage percentages disclosed herein are based on the total linkages of an alpha- glucan, or the portion of an alpha-glucan for which a disclosure specifically regards. The terms “linkage”, “glycosidic linkage”, “glycosidic bond” and the like refer to the covalent bonds connecting the sugar monomers within a saccharide compound (oligosaccharides and/or polysaccharides). Examples of glycosidic linkages include 1,6- alpha-D-glycosidic linkages (herein also referred to as “alpha-1,6” linkages), 1,3-alpha- D-glycosidic linkages (herein also referred to as “alpha-1,3” linkages), 1,4-alpha-D- glycosidic linkages (herein also referred to as “alpha-1,4” linkages), and 1,2-alpha-D- glycosidic linkages (herein also referred to as “alpha-1,2” linkages). The glycosidic linkage profile of a polysaccharide or derivative thereof can be determined using any method known in the art. For example, a linkage profile can be determined using methods using nuclear magnetic resonance (NMR) spectroscopy (e.g., ¹³C NMR and/or ¹H NMR). These and other methods that can be used are disclosed in, for example, Food Carbohydrates: Chemistry, Physical Properties, and Applications (S. W. Cui, Ed., Chapter 3, S. W. Cui, Structural Analysis of Polysaccharides, Taylor & Francis Group LLC, Boca Raton, FL, 2005), which is incorporated herein by reference. The “molecular weight” of a polysaccharide or polysaccharide derivative herein can be represented as weight-average molecular weight (Mw) or number-average molecular weight (Mn), the units of which are in Daltons (Da) or grams/mole. Alternatively, molecular weight can be represented as DPw (weight average degree of polymerization) or DPn (number average degree of polymerization). The molecular weight of smaller polysaccharide polymers such as oligosaccharides can optionally be provided as “DP” (degree of polymerization), which simply refers to the number of monomers comprised within the polysaccharide; “DP” can also characterize the molecular weight of a polymer on an individual molecule basis. Various means are known in the art for calculating these various molecular weight measurements such as with high-pressure liquid chromatography (HPLC), size exclusion chromatography (SEC), or gel permeation chromatography (GPC). As used herein, Mw can be calculated as Mw = ΣNiMi² / ΣNiMi; where Mi is the molecular weight of an individual chain i and Ni is the number of chains of that molecular weight. Besides SEC, the Mw of a polymer can be determined by other techniques such as static light scattering, mass spectrometry, MALDI-TOF (matrix-assisted laser desorption/ionization time-of-flight), small angle X-ray or neutron scattering, or ultracentrifugation. As used herein, Mn can be calculated as Mn = ΣNiMi / ΣNi where Mi is the molecular weight of a chain i and Ni is the number of chains of that molecular weight. Besides SEC, the Mn of a polymer can be determined by various colligative property methods such as vapor pressure osmometry, end-group determination by spectroscopic methods such as proton NMR, proton FTIR, or UV-Vis. As used herein, DPw and DPn can be calculated from Mw and Mn, respectively, by dividing them by molar mass of the one monomer unit M₁. In the case of unsubstituted glucan polymer, M1 = 162. In the case of a substituted (derivatized) glucan polymer, M1 = 162 + Mf x DoS, where Mf is molar mass of the substituting group, and DoS is degree of substitution (average number of substituted groups per one glucose unit of the glucan polymer). “Ethylene glycol diglycidyl ether” (EGDE), “1,2-bis(2,3-epoxypropoxy)ethane” and like terms herein refer to the compound of CAS no.2224-15-9, which has the following structure:

EGDE can be used herein for crosslinking alpha-glucan derivatives. The terms “crosslink”, “crosslinked” and the like herein as applying to a crosslinked alpha-glucan derivative compound refer to one or more covalent bonds (chemical bonds) that connect polymers. A crosslink having multiple bonds typically comprises one or more atoms that are part of a crosslinking agent (e.g., EGDE) that was used to form the crosslink. The term “crosslinking reaction” and like terms (e.g., “crosslinking composition”, “crosslinking preparation”) herein typically refer to a reaction comprising at least a solvent, crosslinking agent (e.g., EGDE), and alpha-glucan derivative. A crosslinking reaction in some aspects comprises an aqueous solvent such as water. A “crosslinked alpha-glucan derivative”, “EGDE-crosslinked alpha-glucan derivative”, and like terms herein typically refer to an alpha-glucan derivative (e.g., an alpha-glucan derivatized with ether-linked organic groups, sulfonate groups, and/or with groups borne from oxidation) that has been contacted with the crosslinking compound EGDE, typically under suitable conditions (typically including aqueous conditions) for the EGDE to react with and crosslink the alpha-glucan derivative. For ease of reference herein, an alpha-glucan derivative that serves as a substrate in an EGDE treatment/contacting reaction can be referred to as a “first alpha-glucan derivative”; typically, mention herein of any alpha-glucan derivative can refer to a first alpha-glucan derivative. An organic group herein typically is uncharged (nonionic) or charged (e.g., anionic); generally, such charge can be as it exists when the organic group is in an aqueous composition herein, further taking into account the pH of the aqueous composition (in some aspects, the pH can be 4-10 or 5-9, or any pH as disclosed herein). If present in a first alpha-glucan derivative herein, an organic group that comprises a carboxylic acid or carboxylate group can be a carboxylic acid or carboxylate group by itself (e.g., carbon 6 of glucose can be -COOH or -COO-), or can be an organic group that is (i) ether-, ester-, carbamate-, sulfonyl-, or carbonate-linked to the alpha- glucan and (ii) comprises a carboxylic acid or carboxylate group (e.g., a carboxy alkyl group such as carboxymethyl). The term “degree of substitution” (DoS, or DS) as used herein refers to the average number of hydroxyl groups that are substituted with one or more organic groups (e.g., via an ether, ester, or other linkage herein), sulfonate groups, and/or oxidation- borne groups in each monomeric unit of an alpha-glucan derivative. The DoS of an alpha-glucan derivative herein can be stated with reference to the DoS of a specific substituent, or the overall DoS, which is the sum of the DoS values of different substituent types. Unless otherwise disclosed, when DoS is not stated with reference to a specific substituent type, the overall DoS is meant. Terms used herein regarding “ethers” (e.g., alpha-glucan ether derivative) can be as disclosed, for example, in U.S. Patent Appl. Publ. Nos.2014/179913, 2016/0304629, 2015/0239995, 2018/0230241, 2018/0237816, 2020/0002646, 2023/0212325, 2023/0235097, or 2024/0301325, or Int. Patent Appl. Publ. No. WO2021/257786, which are each incorporated herein by reference. The terms “alpha-glucan ether derivative”, “alpha-glucan ether compound”, “alpha-glucan ether”, and the like are used interchangeably herein. An alpha-glucan ether derivative herein is an alpha-glucan that has been etherified with one or more organic groups (e.g., uncharged, anionic) such that the derivative has a DoS with one or more organic groups of up to about 3.0. An alpha- glucan ether derivative is termed an “ether” herein by virtue of comprising the substructure -C_G-O-C-, where “-C_G-” represents a carbon atom of a monomeric unit of the alpha-glucan ether derivative (where such carbon atom was bonded to a hydroxyl group [-OH] in the alpha-glucan precursor of the ether), and where “-C-” is a carbon atom of an organic group. A “sulfonate” group herein can be as disclosed, for example, in Int. Pat. Appl. Publ. No. WO2019/246228, or U.S. Pat. Appl. Publ. No.2021/0253977, which are each incorporated herein by reference. An “oxidized alpha-glucan derivative” (and like terms) herein refers to a compound resulting from oxidation of an alpha-glucan derivative such as presently disclosed. Such oxidation can occur, for example, at one or more hydroxyl groups of monomeric units of a alpha-glucan derivative, and/or at one or more hydroxyl groups of substituting organic groups of the alpha-glucan derivative. Oxidation can independently convert hydroxyl groups to an aldehyde, ketone, or carboxylic group. An alpha-glucan derivative herein can be oxidized by contacting it with one or more oxidizing/oxidation agents under aqueous conditions, for example. In some aspects, an oxidized alpha- glucan derivative is one that has been produced by oxidizing an alpha-glucan derivative (e.g., an alpha-glucan ether herein), essentially thus further derivatizing the alpha- glucan. In some aspects, an alpha-glucan derivative can be oxidized before (typically), or after, it has been crosslinked herein and optionally further organic group-derivatized. An oxidation reaction herein can be performed, for example, as disclosed in the below Examples or as disclosed in Int. Pat. Appl. Publ. Nos. WO2022/178073 or WO2022/178075, or U.S. Pat. Appl. Publ. Nos.2024/0199766 or 2024/0150497, which are each incorporated herein by reference. The terms “aqueous liquid”, “aqueous fluid”, “aqueous conditions”, “aqueous reaction conditions”, “aqueous setting”, “aqueous system” and the like as used herein can refer to water or an aqueous solution. An “aqueous solution” herein can comprise one or more dissolved salts, where the maximal total salt concentration can be about 3.5 wt% in some aspects. Although aqueous liquids herein typically comprise water as the only solvent in the liquid, an aqueous liquid can optionally comprise one or more other solvents (e.g., polar organic solvent) that are miscible in water. Thus, an aqueous solution can comprise a solvent having at least about 10 wt% water. An “aqueous composition” herein has a liquid component that comprises about, or at least about, 10, 20, 30, 40, 50, 60, 70, 80, 90, 95, 99, or 100 wt% water, for example. Examples of aqueous compositions include mixtures, solutions, dispersions (e.g., suspensions, colloidal dispersions) and emulsions, for example. Compositions of the present disclosure can provide stability to a dispersion or emulsion in some aspects. The “stability” (or the quality of being “stable”) of a dispersion or emulsion herein is, for example, the ability of dispersed particles of a dispersion, or liquid droplets dispersed in another liquid (emulsion), to remain dispersed (e.g., about, or at least about, 70, 75, 80, 85, 90, 95, 96, 97, 98, 99, or 100 wt% of the particles of the dispersion or liquid droplets of the emulsion are in a dispersed state) for a period of about, or at least about, 2, 4, 6, 9, 12, 18, 24, 30, or 36 months following initial preparation of the dispersion or emulsion. A stable dispersion or emulsion in some aspects can resist total sedimentation, flocculation, and/or coalescence of dispersed/emulsified material. An alpha-glucan derivative herein that is “soluble”, “aqueous-soluble”, or “water- soluble” (and like terms) herein dissolves (or appreciably dissolves) in water or other aqueous conditions, optionally where the aqueous conditions are further characterized to have a pH of 4-9 (e.g., pH 6-8) and/or temperature of about 1 to 130 °C (e.g., 20-25 °C). In some aspects, an aqueous-soluble alpha-glucan derivative is soluble at 1% by weight or higher in pH 7 water at 25 °C. In contrast, an alpha-glucan derivative that is “insoluble”, “aqueous-insoluble”, or “water-insoluble” (and like terms) does not dissolve under these conditions. In some aspects, less than 1.0 gram (e.g., no detectable amount) of an aqueous-insoluble alpha-glucan derivative dissolves in 1000 milliliters of such aqueous conditions (e.g., water at 23 °C). The term “household care product” and like terms typically refer to products, goods and services relating to the treatment, cleaning, caring and/or conditioning of a home and its contents. The foregoing include, for example, chemicals, compositions, products, or combinations thereof having application in such care. The terms “fabric”, “textile”, “cloth” and the like are used interchangeably herein to refer to a woven material having a network of natural and/or artificial fibers. Such fibers can be in the form of thread or yarn, for example. A “fabric care composition” and like terms refer to any composition suitable for treating fabric in some manner. Examples of such a composition include laundry detergents and fabric softeners, which are examples of laundry care compositions. A “detergent composition” herein typically comprises at least a surfactant (detergent compound) and/or a builder. A “surfactant” herein refers to a substance that tends to reduce the surface tension of a liquid in which the substance is dissolved. A surfactant may act as a detergent, wetting agent, emulsifier, foaming agent, and/or dispersant, for example. The terms “heavy duty detergent”, “all-purpose detergent” and the like are used interchangeably herein to refer to a detergent useful for regular washing of white and/or colored textiles at any temperature. The terms “low duty detergent”, “fine fabric detergent” and the like are used interchangeably herein to refer to a detergent useful for the care of delicate fabrics such as viscose, wool, silk, microfiber, or other fabric requiring special care. “Special care” can include conditions of using excess water, low agitation, and/or no bleach, for example. The terms “builder”, “builder agent” and the like herein refer to compositions that, for example, can complex with hard water cations such as calcium and magnesium cations. Such complex formation is believed to prevent the formation of water-insoluble salts and/or other complexes by the cation(s). In the context of a detergent composition for cleaning or maintenance applications, a builder added thereto typically can enhance or maintain the cleaning efficiency of a surfactant present in the detergent composition. The terms “builder capacity”, “builder activity” and the like are used interchangeably herein and refer to the ability of an aqueous composition to exhibit features endowed by one or more builders present in the aqueous composition. A crosslinked alpha-glucan derivative in some aspects herein can be used as a builder. The terms “flocculant”, “flocculation agent”, “flocculation composition”, “agglomeration agent”, and the like herein refer to substances that can promote agglomeration/clumping/coalescence of insoluble particles suspended in water or other aqueous liquid, thereby rendering the particles more easy to remove by settling/sedimentation, filtration, pelleting, and/or other suitable means. Flocculation of particles typically can be performed in a process of removing/separating particles from an aqueous suspension. A crosslinked alpha-glucan derivative in some aspects herein can be used as a flocculant. The term “personal care product” and like terms typically refer to products, goods and services relating to the treatment, cleaning, cleansing, caring or conditioning of a person. The foregoing include, for example, chemicals, compositions, products, or combinations thereof having application in such care. The terms “ingestible product”, “ingestible composition” and the like refer to any substance that, either alone or together with another substance, may be taken orally (i.e., by mouth). “Non-edible products” (“non-edible compositions”) refer to any composition that can be taken by the mouth for purposes other than food or beverage consumption. Examples of non-edible products herein include supplements, nutraceuticals, functional food products, pharmaceutical products, oral care products (e.g., dentifrices, mouthwashes), and cosmetic products such as sweetened lip balms. The term “medical product” and like terms typically refer to products, goods and services relating to the diagnosis, treatment, and/or care of patients. A “pharmaceutical product”, “medicine”, “medication”, “drug” or like term herein refers to a composition used to treat disease or injury, and can be administered enterally or parenterally. The term “industrial product” and like terms typically refer to products, goods and services used in industrial and/or institutional settings, but typically not by individual consumers. The term “viscosity” as used herein refers to the measure of the extent to which a fluid (aqueous or non-aqueous) resists a force tending to cause it to flow. Various units of viscosity that can be used herein include centipoise (cP, cps) and Pascal-second (Pa·s), for example. A centipoise is one one-hundredth of a poise; one poise is equal to 0.100 kg·m^-1·s^-1. Viscosity can be reported as “intrinsic viscosity” (IV, ^, units of dL/g) in some aspects; this term refers to a measure of the contribution of a glucan polymer to the viscosity of a liquid (e.g., solution) comprising the glucan polymer. IV measurements herein can be obtained, for example, using any suitable method such as disclosed in U.S. Pat. Appl. Publ. Nos.2017/0002335, 2017/0002336, or 2018/0340199, or Weaver et al. (J. Appl. Polym. Sci.35:1631-1637) or Chun and Park (Macromol. Chem. Phys. 195:701-711), which are all incorporated herein by reference. IV can be measured, in part, by dissolving glucan polymer (optionally dissolved at about 100 °C for at least 2, 4, or 8 hours) in DMSO with about 0.9 to 2.5 wt% (e.g., 1, 2, 1-2 wt%) LiCl, for example. IV herein can optionally be used as a relative measure of molecular weight. The terms “sequence identity”, “identity” and the like as used herein with respect to a polypeptide amino acid sequence (e.g., that of a glucosyltransferase) are as defined and determined in U.S. Patent Appl. Publ. No.2017/0002336, which is incorporated herein by reference. A composition herein that is “dry” or “dried” typically has less than 6, 5, 4, 3, 2, 1, 0.5, or 0.1 wt% water comprised therein. The terms “percent by volume”, “volume percent”, “vol %”, “v/v %” and the like are used interchangeably herein. The percent by volume of a solute in a solution can be determined using the formula: [(volume of solute)/(volume of solution)] x 100%. The terms “percent by weight”, “weight percentage (wt%)”, “weight-weight percentage (% w/w)” and the like are used interchangeably herein. Percent by weight refers to the percentage of a material on a mass basis as it is comprised in a composition, mixture, or solution. The terms “weight/volume percent”, “w/v%” and the like are used interchangeably herein. Weight/volume percent can be calculated as: ((mass [g] of material)/(total volume [mL] of the material plus the liquid in which the material is placed)) x 100%. The material can be insoluble in the liquid (i.e., be a solid phase in a liquid phase, such as with a dispersion), or soluble in the liquid (i.e., be a solute dissolved in the liquid). The term “isolated” means a substance (or process) in a form or environment that does not occur in nature. Non-limiting examples of isolated substances include any alpha-glucan derivative or crosslinked alpha-glucan derivative disclosed herein. It is believed that the embodiments disclosed herein are synthetic/man-made (could not have been made or practiced except for human intervention/involvement), and/or have properties that are not naturally occurring. The term “increased” as used herein can refer to a quantity or activity that is at least about 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 50%, 100%, or 200% more than the quantity or activity for which the increased quantity or activity is being compared. The terms “increased”, “elevated”, “enhanced”, “greater than”, “improved” and the like are used interchangeably herein. Some aspects of the present disclosure concern a composition (product) comprising an ethylene glycol diglycidyl ether (EGDE)-crosslinked alpha-glucan derivative. Typically, such a crosslinked alpha-glucan derivative of the present disclosure is produced by contacting EGDE with a first alpha-glucan derivative (i.e., the first alpha-glucan derivative typically has already been derivatized, such as by etherification, sulfonation, or oxidation) under suitable conditions (typically including aqueous conditions) for the EGDE to react with and crosslink the first alpha-glucan derivative, thereby producing an EGDE-crosslinked alpha-glucan derivative. Regarding the relative amounts of EGDE and first alpha-glucan derivative used in such a crosslinking reaction, the ratio of EGDE to the first alpha-glucan derivative can be about 0.03 to 0.07 mole EGDE to about 1 mole of the first alpha-glucan derivative, for example. In some aspects, the ratio of EGDE to the first alpha-glucan derivative can be about 0.04-0.06, 0.04-0.065, 0.04-0.07, 0.035-0.06, 0.035-0.065, 0.035-0.07, 0.03-0.06, or 0.03-0.065 mole EGDE to about 1 mole of the first alpha-glucan derivative. Yet, in some aspects, the ratio of EGDE to the first alpha-glucan derivative can be about 0.03- 0.08, 0.03-0.09, 0.03-0.1, 0.04-0.08, 0.04-0.09, 0.04-0.1, 0.05-0.1, 0.05-0.09, 0.05-0.08, 0.06-0.1, 0.06-0.09, or 0.06-0.08 mole EGDE to about 1 mole of the first alpha-glucan derivative. Crosslinked alpha-glucan derivatives as presently disclosed have several advantageous features, such as being able to prevent/reduce the formation of unwanted deposits resulting from the interaction of hard water cations (e.g., Ca²⁺, Mg²⁺) with anionic compounds (e.g., carbonate, stearate) in various aqueous applications. Crosslinks herein formed using EGDE (“EGDE-based” or “EGDE-derived” crosslinks) can be between two or more alpha-glucan derivative molecules (i.e., intermolecular crosslinks), for example. It is contemplated that EGDE-based crosslinks in some aspects can also be intramolecular, i.e., crosslinking at different points within a single alpha-glucan derivative molecule. A crosslinked alpha-glucan derivative herein can comprise a homogenous or heterogenous alpha-glucan derivative component. A crosslinked alpha-glucan derivative with a homogenous alpha-glucan derivative component can be prepared using one form/type, lot, or preparation of alpha-glucan derivative, for example, such as that made using a particular enzymatic reaction and/or derivatization. A crosslinked alpha-glucan derivative with a heterogenous alpha-glucan derivative component typically can be prepared using two or more different forms/types, lots, or preparations of alpha- glucan derivatives, for example. For example, a heterogenous crosslinked alpha-glucan derivative can comprise two or more alpha-glucan derivatives differing in substitution groups, DoS, molecular weight, and/or glycosidic linkage profile. A composition comprising a crosslinked alpha-glucan derivative herein can, in some aspects, further comprise one or more non-crosslinked alpha-glucan derivatives. Examples of a non-crosslinked alpha-glucan derivative can be the same derivative that was used for crosslinking (i.e., such a composition comprises crosslinked and non- crosslinked forms of the same alpha-glucan derivative) or a different alpha-glucan derivative from the one that was used for crosslinking. A first alpha-glucan derivative herein typically is not already chemically crosslinked prior to being used to produce an EGDE-crosslinked alpha-glucan derivative of the disclosure. Yet, in some alternative aspects herein, an alpha-glucan derivative of the present disclosure has not been crosslinked. An alpha-glucan derivative in some aspects of the disclosure can be an alpha- 1,3-glucan derivative. For example, an alpha-1,3-glucan derivative can serve as a first alpha-glucan derivative for producing an EGDE-crosslinked alpha-glucan derivative. An alpha-1,3-glucan derivative in some aspects can comprise about, or at least about, 50%, 60%, 70%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, or 100% alpha-1,3 glycosidic linkages. In some aspects, accordingly, an alpha-1,3- glucan derivative has about, or less than about, 50%, 40%, 30%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%, or 0% glycosidic linkages that are not alpha- 1,3. Typically, the glycosidic linkages that are not alpha-1,3 are mostly or entirely alpha- 1,6. It should be understood that the higher the percentage of alpha-1,3 linkages present in an alpha-1,3-glucan derivative, the greater the probability that the glucan derivative is linear, since there are lower occurrences of certain linkages that might be part of branch points. In some aspects, an alpha-1,3-glucan derivative has no branch points or less than about 5%, 4%, 3%, 2%, or 1% branch points as a percent of the glycosidic linkages in the alpha-1,3-glucan derivative. The DPw, DPn, or DP of the alpha-1,3-glucan portion of an alpha-1,3-glucan derivative in some aspects can be about, or at least about, 100, 150, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2500, 3000, 3500, or 4000. DPw, DPn, or DP can optionally be expressed as a range between any two of these values. Merely as examples, the DPw, DPn, or DP of the alpha-1,3-glucan portion of an alpha-1,3-glucan derivative can be about 100-1600, 200- 1600, 300-1600, 400-1600, 500-1600, 600-1600, 700-1600, 800-1600, 100-1250, 200- 1250, 300-1250, 400-1250, 500-1250, 600-1250, 700-1250, 800-1250, 100-1000, 200- 1000, 300-1000, 400-1000, 500-1000, 600-1000, 700-1000, 800-1000, 100-800, 200- 800, 300-800, 400-800, 500-800, or 600-800. The alpha-1,3-glucan portion of an alpha- 1,3-glucan derivative in some aspects can have a high molecular weight as reflected by high intrinsic viscosity (IV); e.g., IV can be about, or at least about 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 6-8, 6-7, 6-22, 6-20, 6-17, 6-15, 6-12, 10-22, 10- 20, 10-17, 10-15, 10-12, 12-22, 12-20, 12-17, or 12-15 dL/g. For comparison purposes, note that the IV of alpha-glucan with at least 90% (e.g., about 99% or 100%) alpha-1,3 linkages and a DPw of about 800 has an IV of about 2-2.5 dL/g. IV herein can be as measured with alpha-glucan polymer dissolved in DMSO with about 0.9 to 2.5 wt% (e.g., 1, 2, 1-2 wt%) LiCl, for example. If desired, the molecular weight of a crosslinked alpha- 1,3-glucan derivative herein can be calculated or estimated based on the molecular weight of the first alpha-1,3-glucan derivative (e.g., based on its degree of polymerization and substitution group[s]), and the average number of first alpha-1,3- glucan derivative molecules that crosslinked together. The alpha-1,3-glucan portion of an alpha-1,3-glucan derivative herein can be as disclosed (e.g., molecular weight, linkage profile, production method), for example, in U.S. Patent Nos.7000000, 8871474, 10301604, or 10260053, or U.S. Patent Appl. Publ. Nos.2019/0112456, 2019/0078062, 2019/0078063, 2018/0340199, 2018/0021238, 2018/0273731, 2017/0002335, 2015/0232819, 2015/0064748, 2020/0165360, 2019/0276806, or 2019/0185893, which are each incorporated herein by reference. An alpha-glucan derivative in some aspects of the disclosure can be an alpha- 1,6-glucan (dextran) derivative. For example, an alpha-1,6-glucan (dextran) derivative can serve as a first alpha-glucan derivative for producing an EGDE-crosslinked alpha- glucan derivative. An alpha-1,6-glucan derivative in some aspects can comprise about 100% alpha-1,6-glycosidic linkages (i.e., be completely linear), or about, or at least about, 50%, 60%, 70%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 99.5% alpha-1,6-glycosidic linkages. In some aspects, a substantially linear alpha-1,6-glucan derivative can comprise 5%, 4%, 3%, 2%, 1%, 0.5% or less branches. If present, branches from alpha-1,6-glucan typically are short, being one (pendant), two, or three glucose monomers in length. In some aspects, an alpha-1,6-glucan derivative can comprise, about, at least about, or less than about, 50%, 40%, 30%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%, or 0% alpha-1,4, alpha-1,3, and/or alpha-1,2 glycosidic linkages. Typically, such linkages exist entirely, or almost entirely, as branch points from alpha-1,6-glucan. The alpha-1,6-glucan portion of an alpha-1,6-glucan derivative herein can have alpha-1,2, alpha-1,3, and/or alpha-1,4 branches, for example. In some aspects, about, at least about, or less than about, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 30%, 35%, 40%, 45%, 50%, 2-25%, 2-20%, 2-15%, 2-10%, 3-25%, 3-20%, 3-15%, 3-10%, 5- 30%, 5-25%, 5-20%, 5-15%, 5-10%, 7-13%, 8-12%, 9-11%, 10-30%, 10-25%, 10-22%, 10-20%, 10-15%, 12-20%, 12-18%, 14-20%, 14-18%, 15-30%, 15-25%, 15-20%, 15- 18%, 15-17%, 20-45%, 20-40%, 20-35%, 20-30%, 20-25%, 30-45%, or 30-40% of all the glycosidic linkages of a branched alpha-1,6-glucan are alpha-1,2, alpha-1,3, and/or alpha-1,4 glycosidic branch linkages (in some aspects, alpha-1,2 branches or alpha-1,3 branches are the only type of branches present). Such branches typically are mostly (>90% or >95%), or all (100%), a single glucose monomer in length. In some aspects, alpha-1,6-glucan with alpha-1,2-branching can be produced enzymatically according to the procedures in U.S. Patent Appl. Publ. Nos.2017/0218093 or 2018/0282385 (both incorporated herein by reference) where, for example, an alpha-1,2-branching enzyme such as GTFJ18T1 or GTF9905 can be added during or after the production of the dextran. In some aspects, any other enzyme known to produce alpha-1,2-branching can be used. Alpha-1,6-glucan with alpha-1,3-branching can be prepared, for example, as disclosed in Vuillemin et al. (2016, J. Biol Chem.291:7687-7702) or U.S. Patent Appl. Publ. No.2022/0267745, which are incorporated herein by reference. The alpha-1,6-glucan portion of an alpha-1,6-glucan derivative herein can have a DPw, DPn, or DP of about, at least about, or less than about, 100, 150, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 100-1600, 200- 1600, 300-1600, 400-1600, 500-1600, 600-1600, 700-1600, 800-1600, 100-1250, 200- 1250, 300-1250, 400-1250, 500-1250, 600-1250, 700-1250, 800-1250, 100-1000, 200- 1000, 300-1000, 400-1000, 500-1000, 600-1000, 700-1000, 800-1000, 100-800, 200- 800, 300-800, 400-800, 500-800, or 600-800, for example. In some aspects, the alpha- 1,6-glucan portion of an alpha-1,6-glucan derivative herein can have a Mw of about 5, 10, 15, 20, 25, 30, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275, 300, 5-30, 5-25, 5-20, 10-30, 10-25, 10-20, 150-225, 150-200, 165-225, 165-200, 175-225, 175-200, 180-190, 5-250, 5-200, 10-250, or 10-200 kDa. Any of the forgoing DPw, DPn, DP, or Mw values/ranges can characterize an alpha-1,6-glucan herein before, or after, it has optionally been branched (e.g., alpha-1,2 and/or alpha-1,3), for instance. In some aspects, any of the forgoing DPw, DPn, DP, or Mw values/ranges can characterize an alpha-1,6-glucan derivative herein. If desired, the molecular weight of a crosslinked alpha-1,6-glucan derivative herein can be calculated or estimated based on the molecular weight of the first alpha-1,6-glucan derivative (e.g., based on its degree of polymerization and substitution group[s]), and the average number of first alpha-1,6- glucan derivative molecules that are crosslinked together. The alpha-1,6-glucan portion of an alpha-1,6-glucan derivative herein can be as disclosed (e.g., molecular weight, linkage/branching profile, production method), for example, in U.S. Patent Appl. Publ. Nos.2016/0122445, 2017/0218093, 2018/0282385, 2020/0165360, or 2019/0185893, which are each incorporated herein by reference. In some aspects, an alpha-1,6-glucan for derivatization herein can be one produced in a suitable reaction comprising glucosyltransferase (GTF) 0768 (SEQ ID NO:1 or 2 of US2016/0122445), GTF 8117, GTF 6831, or GTF 5604 (these latter three GTF enzymes are SEQ ID NOs:30, 32 and 33, respectively, of US2018/0282385), or a GTF comprising an amino acid sequence that is at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% identical to the amino acid sequence of GTF 0768, GTF 8117, GTF 6831, or GTF 5604. An alpha-glucan derivative in some aspects, such as a first alpha-glucan derivative for producing an EGDE-crosslinked (or any type crosslinked) alpha-glucan derivative, can have a degree of substitution (DoS) up to about 3.0 (e.g., 0.001 to 3.0) with at least one group, such as an organic group (e.g., via an ether, ester, sulfonyl, carbamate/carbamoyl, carbonate, or other linkage), sulfonate group, and/or oxidation- borne (oxidation-generated) group. The DoS can be about, at least about, or up to about, 0.001, 0.0025, 0.005, 0.01, 0.025, 0.05, 0.075, 0.1, 0.2, 0.25, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, or 3.0 (DoS can optionally be expressed as a range between any two of these values), for example. Some examples of DoS ranges herein include 0.005-2.0, 0.005-1.6, 0.005-1.5, 0.005-1.25, 0.005-1.0, 0.005-0.9, 0.005-0.8, 0.005-0.7, 0.005-0.6, 0.005-0.5, 0.005-0.25, 0.005-0.1, 0.04-0.1, 0.05-2.0, 0.05-1.6, 0.05-1.5, 0.05-1.25, 0.05- 1.0, 0.05-0.9, 0.05-0.8, 0.05-0.7, 0.05-0.6, 0.05-0.5, 0.1-2.0, 0.1-1.6, 0.1-1.5, 0.1-1.25, 0.1-1.0, 0.1-0.9, 0.1-0.8, 0.1-0.7, 0.1-0.6, 0.1-0.5, 0.15-2.0, 0.15-1.6, 0.15-1.5, 0.15-1.25, 0.15-1.0, 0.15-0.9, 0.15-0.8, 0.15-0.7, 0.15-0.6, 0.15-0.5, 0.2-2.0, 0.2-1.6, 0.2-1.5, 0.2- 1.25, 0.2-1.0, 0.2-0.9, 0.2-0.8, 0.2-0.7, 0.2-0.6, 0.2-0.5, 0.25-2.0, 0.25-1.6, 0.25-1.5, 0.25-1.25, 0.25-1.0, 0.25-0.9, 0.25-0.8, 0.25-0.7, 0.25-0.6, 0.25-0.5, 0.3-2.0, 0.3-1.6, 0.3- 1.5, 0.3-1.25, 0.3-1.0, 0.3-0.9, 0.3-0.8, 0.3-0.7, 0.3-0.6, 0.3-0.5, 0.4-2.0, 0.4-1.6, 0.4-1.5, 0.4-1.25, 0.4-1.0, 0.4-0.9, 0.4-0.8, 0.4-0.7, 0.4-0.6, and 0.4-0.5. In some aspects, a mixed alpha-glucan derivative herein such as one having two or more different organic groups (e.g., an ether-, ester-, carbamate/carbamoyl-, sulfonyl-, or carbonate-linked organic group) and/or other substituent groups (e.g., sulfonate or carboxylate group), can be characterized to have any of the foregoing DoS values/ranges (where this DoS value/range regards the total DoS of all the substituents combined, or the DoS of any one particular substituent [i.e., on an individual basis]). Since there are at most three hydroxyl groups in a glucose monomeric unit of an alpha-glucan, the overall DoS of an alpha-glucan derivative can be no higher than 3.0. It would be understood that, since a glucan derivative as presently disclosed has a DoS with at least one group that is not only hydrogen (e.g., between about 0.001 to about 3.0), such as an organic group, all the substituents of a glucan derivative cannot only be hydroxyl. In some aspects, a first alpha-glucan derivative has a DoS of about 0.35 to 2.5, 0.4 to 2.5, 0.4 to 1.0, or 0.35 to 1.0 with a group herein such as an etherified organic group, a sulfonate group, or a group resulting from oxidation (e.g., a carboxylate group), and/or where such a group is anionic (negatively charged). An etherified organic group can be a carboxyalkyl group such as a carboxymethyl group, for example. Optionally, such a first alpha-glucan derivative can further be substituted (e.g., via ether linkage) with an organic group comprising an aryl group; such an organic group can be benzyl or a substituted benzyl (e.g., as above), for example. Such a first alpha-glucan derivative can be an alpha-1,3-glucan derivative herein, such as one comprising about, or at least about, 90%, 95%, 99%, or 100% alpha-1,3 glycosidic linkages. In some aspects, a first alpha-glucan derivative has a DoS of at least about 2.0, 2.25, or 2.5, or a DoS of about 2.3 to 2.6 with a group herein such as an etherified organic group, a sulfonate group, or a group resulting from oxidation (e.g., a carboxylate group), and/or where such a group is anionic (negatively charged). An etherified organic group can be a carboxyalkyl group such as a carboxymethyl group, for example. Optionally, such a first alpha-glucan derivative can further be substituted (e.g., via ether linkage) with an organic group comprising an aryl group; such an organic group can be benzyl or a substituted benzyl (e.g., as below), for example. Such a first alpha-glucan derivative can be an alpha-1,6-glucan derivative herein having at least about 50% alpha- 1,6 glycosidic linkages and typically also having alpha-1,2 and/or alpha-1,3 branches (e.g., only alpha-1,2 branches present). An alpha-glucan derivative herein, such as a first alpha-glucan derivative, can be substituted with at least one group, for example, such as an organic group. A substituting group can be linked to an alpha-glucan derivative via an ether linkage, ester linkage, carbamate/carbamoyl linkage, carbonate linkage, or sulfonyl linkage, for example. Thus, an alpha-glucan derivative in some aspects can also be characterized as an alpha-glucan ether, ester, carbamate, carbonate, or sulfonyl derivative. An organic group herein typically can be considered to comprise at least one carbon atom and at least one hydrogen atom. An organic group that is in ether-linkage to an alpha-glucan derivative herein (e.g., a first alpha-glucan derivative) can be an alkyl group, for example. An alkyl group can be a linear, branched, or cyclic (“cycloalkyl” or “cycloaliphatic”) in some aspects. In some aspects, an alkyl group is a C1 to C18 alkyl group, such as a C4 to C18 alkyl group, ^{or a C} ₁ ^{to C} ₁₀ ^{alkyl group (in “C} _# ^{”, # refers to the number of carbon atoms in the alkyl} group). An alkyl group can be, for example, a methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecanyl, tetradecanyl, pentadecanyl, hexadecanyl, heptadecanyl, or octadecanyl group; such alkyl groups typically are linear. One or more carbons of an alkyl group can be substituted with another alkyl group in some aspects, making the alkyl group branched. Suitable examples of branched chain isomers of linear alkyl groups include isopropyl, iso-butyl, tert-butyl, sec-butyl, isopentyl, neopentyl, isohexyl, neohexyl, 2-ethylhexyl, 2-propylheptyl, and isooctyl. In some aspects, an alkyl group is a cycloalkyl group such as a cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl, cyclononyl, or cyclodecyl group. In some aspects, an organic group that is in ether-linkage to an alpha-glucan derivative herein can be a substituted alkyl group in which there is a substitution on one or more carbons of the alkyl group. The substitution(s) can be one or more hydroxyl, aldehyde, ketone, and/or carboxyl groups. For example, a substituted alkyl group may be a hydroxy alkyl group, dihydroxy alkyl group, or carboxy alkyl group. Examples of suitable hydroxy alkyl groups are hydroxymethyl (-CH2OH), hydroxyethyl (e.g., -CH₂CH₂OH, -CH(OH)CH₃), hydroxypropyl (e.g., -CH₂CH₂CH₂OH, -CH₂CH(OH)CH₃, -CH(OH)CH₂CH₃), hydroxybutyl and hydroxypentyl groups. Other examples include dihydroxy alkyl groups (diols) such as dihydroxymethyl, dihydroxyethyl (e.g., -CH(OH)CH2OH), dihydroxypropyl (e.g., -CH2CH(OH)CH2OH, -CH(OH)CH(OH)CH3), dihydroxybutyl and dihydroxypentyl groups. Examples of suitable carboxy alkyl groups are carboxymethyl (-CH2COOH), carboxyethyl (e.g., -CH2CH2COOH, -CH(COOH)CH3), carboxypropyl (e.g., -CH₂CH₂CH₂COOH, -CH₂CH(COOH)CH₃, -CH(COOH)CH₂CH₃), carboxybutyl and carboxypentyl groups. In some aspects, one or more carbons of an alkyl group that is in ether-linkage to an alpha-glucan derivative herein can have a substitution(s) with another alkyl group. Examples of such substituent alkyl groups are methyl, ethyl and propyl groups. To illustrate, an organic group can be -CH(CH3)CH2CH3 or -CH2CH(CH3)CH3, for example, which are both propyl groups having a methyl substitution. As should be clear from the above examples of various substituted alkyl groups, a substitution (e.g., hydroxy or carboxy group) on an alkyl group in some aspects can be at the terminal carbon atom of the alkyl group, where the terminal carbon group is opposite the side of the alkyl group that is in ether linkage to a monomeric unit (e.g., glucose) of an alpha-glucan ether compound. An example of this terminal substitution is the hydroxypropyl group -CH₂CH₂CH₂OH. Alternatively, a substitution can be on an internal carbon atom of an alkyl group. An example of an internal substitution is the hydroxypropyl group -CH₂CH(OH)CH₃. An alkyl group can have one or more substitutions, which may be the same (e.g., two hydroxyl groups [dihydroxy]) or different (e.g., a hydroxyl group and a carboxyl group). Optionally, an etherified alkyl group herein can contain one or more heteroatoms such as oxygen, sulfur, and/or nitrogen within the hydrocarbon chain. Examples include alkyl groups containing an alkyl glycerol alkoxylate moiety (-alkylene- OCH₂CH(OH)CH₂OH), a moiety derived from ring-opening of 2-ethylhexl glycidyl ether, and a tetrahydropyranyl group (e.g., as derived from dihydropyran). Further examples include alkyl groups substituted at their termini with a cyano group (-C≡N); such a substituted alkyl group can optionally be referred to as a nitrile or cyanoalkyl group. Examples of a cyanoalkyl group herein include cyanomethyl, cyanoethyl, cyanopropyl and cyanobutyl groups. In some aspects, an etherified organic group is a C2 to C18 (e.g., C4 to C18) alkenyl group, and the alkenyl group may be linear, branched, or cyclic. As used herein, the term “alkenyl group” refers to a hydrocarbon group containing at least one carbon- carbon double bond. Examples of alkenyl groups include ethenyl, propenyl, butenyl, pentenyl, hexenyl, cyclohexyl, and allyl groups. In some aspects, one or more carbons of an alkenyl group can have substitution(s) with an alkyl group, hydroxyalkyl group, or dihydroxy alkyl group such as disclosed herein. Examples of such a substituent alkyl group include methyl, ethyl, and propyl groups. Optionally, an alkenyl group herein can contain one or more heteroatoms such as oxygen, sulfur, and/or nitrogen within the hydrocarbon chain; for example, an alkenyl group can contain a moiety derived from ring-opening of an allyl glycidyl ether. In some aspects, an etherified organic group is a C₂ to C₁₈ alkynyl group. As used herein, the term “alkynyl” refers to linear and branched hydrocarbon groups containing at least one carbon-carbon triple bond. An alkynyl group herein can be, for example, propynyl, butynyl, pentynyl, or hexynyl. An alkynyl group can optionally be substituted, such as with an alkyl, hydroxyalkyl, and/or dihydroxy alkyl group. Optionally, an alkynyl group can contain one or more heteroatoms such as oxygen, sulfur, and/or nitrogen within the hydrocarbon chain. In some aspects, an etherified organic group is a polyether comprising repeat units of (-CH2CH2O-), (-CH2CH(CH3)O-), or a mixture thereof, wherein the total number of repeat units is in the range of 2 to 100. In some aspects, an organic group is a polyether group comprising (-CH₂CH₂O-)_3-100 or (-CH₂CH₂O-)_4-100. In some aspects, an organic group is a polyether group comprising (-CH₂CH(CH₃)O-)_3-100 or (-CH₂CH(CH₃)O-)_4-100. As used herein for a polyether group, the subscript designating a range of values designates the potential number of repeat units; for example, (CH2CH2O)2-100 means a polyether group containing 2 to 100 repeat units. In some aspects, a polyether group herein can be capped such as with a methoxy, ethoxy, or propoxy group. In some aspects, an etherified organic group comprises an aryl group. As used herein, the term “aryl” means an aromatic/carbocyclic group having a single ring (e.g., phenyl), multiple rings (e.g., biphenyl), or multiple condensed rings in which at least one is aromatic, (e.g., 1,2,3,4-tetrahydronaphthyl, naphthyl, anthryl, or phenanthryl), which is optionally mono-, di-, or trisubstituted with alkyl groups, such as a methyl, ethyl, or propyl group. In some aspects, an aryl group is a C₆ to C₂₀ aryl group. In some aspects, an aryl group is a methyl-substituted aryl group such as a tolyl (-C₆H₄CH₃) or xylyl [- C6H3(CH3)2] group. A tolyl group can be a p-tolyl group, for instance. In some aspects, an aryl group is a benzyl group (-CH2-phenyl). A benzyl group herein can optionally be substituted (typically on its phenyl ring) with one or more of a halogen, cyano, ester, amide, ether, alkyl (e.g., C₁ to C₆), aryl (e.g., phenyl), alkenyl (e.g., C₂ to C₆), or alkynyl (e.g., C₂ to C₆) group. An alpha-glucan derivative that has an ether group in some aspects can contain one type of etherified organic group. Examples of such compounds contain a carboxy alkyl group (e.g., carboxymethyl) as the only etherified organic group. Further examples include alpha-glucan ethers containing an alkyl group (e.g., methyl, ethyl, propyl) as the only etherified organic group. Further examples include alpha-glucan ethers containing a dihydroxyalkyl (e.g., dihydroxypropyl) as the only etherified organic group. An alpha-glucan derivative that has an ether group in some aspects can contain two or more different types of etherified organic groups (i.e., mixed ether of the alpha- glucan). Examples of such alpha-glucan ethers contain (i) two different alkyl groups as etherified organic groups, (ii) an alkyl group and a hydroxy alkyl group as etherified organic groups (alkyl hydroxyalkyl alpha-glucan), (iii) an alkyl group and a carboxy alkyl group as etherified organic groups (alkyl carboxyalkyl alpha-glucan), (iv) a hydroxy alkyl group and a carboxy alkyl group as etherified organic groups (hydroxyalkyl carboxyalkyl alpha-glucan), (v) two different hydroxy alkyl groups as etherified organic groups, (vi) two different carboxy alkyl groups as etherified organic groups, or (vii) a carboxy alkyl group (e.g., carboxymethyl) and an aryl (e.g., benzyl) group. Non-limiting examples of some of these types of mixed ethers include ethyl hydroxyethyl alpha-glucan, hydroxyalkyl methyl (e.g., hydroxypropyl methyl) alpha-glucan, carboxymethyl hydroxyethyl alpha-glucan, carboxymethyl hydroxypropyl alpha-glucan, and carboxymethyl benzyl alpha-glucan. The ether groups of a mixed alpha-glucan ether can be, in some instances, as disclosed in U.S. Patent Appl. Publ. No.2020/0002646, which is incorporated herein by reference. An alpha-glucan derivative herein can include one or more ester groups in some aspects. An ester group of an alpha-glucan derivative can comprise, for example, at least one acyl group -CO-R’, wherein R’ comprises a chain of 1 to 26 carbon atoms. R’ can be linear, branched, or cyclic, for example. Examples of acyl groups herein that are linear include ethanoyl, propanoyl, butanoyl, pentanoyl, hexanoyl, heptanoyl, octanoyl, nonanoyl, decanoyl, undecanoyl, dodecanoyl, tridecanoyl, tetradecanoyl, pentadecanoyl, hexadecanoyl, heptadecanoyl, octadecanoyl, nonadecanoyl, eicosanoyl, uneicosanoyl, docosanoyl, tricosanoyl, tetracosanoyl, pentacosanoyl, and hexacosanoyl. Common names for some of the above-listed acyl groups are acetyl (ethanoyl group), propionyl (propanoyl group), butyryl (butanoyl group), valeryl (pentanoyl group), caproyl (hexanoyl group); enanthyl (heptanoyl group), caprylyl (octanoyl group), pelargonyl (nonanoyl group), capryl (decanoyl group), lauroyl (dodecanoyl group), myristyl (tetradecanoyl group), palmityl (hexadecanoyl group), stearyl (octadecanoyl group), arachidyl (eicosanoyl group), behenyl (docosanoyl group), lignoceryl (tetracosanoyl group), and cerotyl (hexacosanoyl group). In some aspects, an acyl group of an alpha-glucan derivative comprises an aryl group. An aryl acyl group can comprise a benzoyl group (-CO-C₆H₅), for example, which can also be referred to as a benzoate group. An aryl acyl group in some aspects can comprise a benzoyl group substituted with at least one halogen (“X”; e.g., Cl, F), alkyl, halogenated alkyl, ether, cyano, or aldehyde group, or combinations thereof, such as represented by the following Structures III(a) through III(r):

An alpha-glucan derivative that has an ester group in some aspects can contain one type of esterified acyl group. An example of such a derivative contains an acetyl group as the only esterified acyl group. Yet, in some aspects, an alpha-glucan derivative can contain two or more different types of esterified acyl groups (i.e., mixed ester of the alpha-glucan). Examples of such mixed esters include those with at least (i) acetyl and propionyl groups, (ii) acetyl and butyryl groups, and (iii) propionyl and butyryl groups. Acyl groups of an alpha-glucan ester derivative herein can be as disclosed, for example, in U.S. Patent Appl. Publ. Nos.2014/0187767, 2018/0155455, 2020/0308371, or 2023/0287148, or Int. Patent Appl. Publ. No. WO2021/252575, which are each incorporated herein by reference. An alpha-glucan derivative herein can include one or more carbamate/carbamoyl groups in some aspects. A carbamate group of an alpha-glucan derivative can be derived from an aliphatic, cycloaliphatic, or aromatic monoisocyanate. In some aspects, a substituent of an alpha-glucan derivative can be a carbamate-linked phenyl, benzyl, diphenyl methyl, or diphenyl ethyl group; these groups can optionally be derived, respectively, using an aromatic monoisocyanate such as phenyl, benzyl, diphenyl methyl, or diphenyl ethyl isocyanate. In some aspects, a substituent of an alpha-glucan derivative can be a carbamate-linked ethyl, propyl, butyl, tert-butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, or octadecyl group; these groups can optionally be derived, respectively, using an aliphatic monoisocyanate such as ethyl, propyl, butyl, tert-butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, or octadecyl isocyanate. In some aspects, a substituent of an alpha-glucan derivative can be a carbamate-linked cyclohexyl, cycloheptyl, or cyclododecyl group; these groups can optionally be derived, respectively, using a cycloaliphatic monoisocyanate such as cyclohexyl, cycloheptyl, or cyclododecyl isocyanate. Carbamate groups of an alpha-glucan derivative herein can be as disclosed, for example, in U.S. Pat. Appl. Publ. Nos.2022/0033531 or 2023/0212325, or Int. Pat. Appl. Publ. No. WO2021/252569, which are each incorporated herein by reference. An alpha-glucan derivative herein can include one or more sulfonyl groups in some aspects. Sulfonyl groups of an alpha-glucan derivative herein can be as disclosed, for example, in Int. Pat. Appl. Publ. No. WO2021/252569 or U.S. Pat. Appl. Publ. No.2023/0212325, which are incorporated herein by reference. The present disclosure also concerns a method of producing a crosslinked alpha- glucan derivative. Such a method typically comprises: (a) contacting ethylene glycol diglycidyl ether (EGDE) with a first alpha-glucan derivative (under suitable conditions, typically including aqueous conditions, for the EGDE to react with and crosslink the first alpha-glucan derivative), thereby crosslinking the first alpha-glucan derivative (thus producing an EGDE-crosslinked alpha-glucan derivative), wherein the ratio of the EGDE to the first alpha-glucan derivative is about 0.03 to 0.07 mole (e.g., about 0.04 to 0.06 mole) EGDE to about 1 mole first alpha- glucan derivative; and (b) optionally isolating the crosslinked alpha-glucan derivative. Any of the features described herein regarding a crosslinked alpha-glucan derivative can characterize this crosslinking method. Methodology parameters (e.g., incubation time, temperature, reagent [e.g., solvent, pH modifier/buffer], reagent [e.g., EGDE] concentration, alpha-glucan derivative substrate concentration, and/or step order) for EGDE-crosslinking an alpha-glucan derivative can be any of those as disclosed in the below Examples, or be within 5%-10% of any of those parameters, as appropriate. A crosslinked alpha-glucan derivative produced in a crosslinking reaction herein can optionally be isolated. In some aspects, such a product can first be precipitated from the aqueous conditions of the reaction. Precipitation, and/or washing of a solid product (regardless of whether it was initially precipitated or not), can be performed by adding an excess amount (e.g., at least 2-3 times the volume of the reaction volume) of an alcohol (e.g., 100% or 95% concentration) such as methanol, ethanol, or isopropanol to the reaction. A product can then be isolated using a filtration funnel, centrifuge, press filter, or any other method or equipment that allows for removal of liquids from solids. The isolated product can be dried, such as by vacuum drying, air drying, or freeze drying. In some aspects, a crosslinked alpha-glucan derivative product can instead be isolated by including a step in which the completed reaction, or a water-diluted form thereof, is filtered by ultrafiltration (e.g., with a 5 or 10 molecular weight cut-off filter). Optionally, a complete reaction or diluted form thereof can first be regularly filtered (i.e., not ultrafiltration), and then the filtrate can be subjected to ultrafiltration. The concentrated liquid obtained by ultrafiltration can then be dried down to its constituent solids such as by freeze-drying, or the solids can be precipitated from the liquid and then dried (e.g., freeze-drying). An alpha-glucan crosslinking reaction can be repeated using a crosslinked alpha- glucan derivative product herein as the starting material for further modification. An alpha-glucan derivative for crosslinking in some aspects is water-insoluble, whereas it is water-soluble in some aspects. A crosslinked alpha-glucan derivative product in some aspects is water-insoluble, whereas it is water-soluble in some aspects. A crosslinked alpha-glucan derivative of the present disclosure can be present in a composition/system, such as an aqueous composition/system or dry composition/system, at about, at least about, or less than about, 0.01, 0.05, 0.1, 0.2, 0.25, 0.3, 0.4, 0.5, 0.6, 0.7, 0.75, 0.8, 0.9, 1.0, 1.2, 1.25, 1.4, 1.5, 1.6, 1.75, 1.8, 2.0, 2.25, 2.5, 3.0, 3.5, 4.0, 4.5, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 0.01-0.1, 0.01-0.08, 0.01-0.06, 0.01-0.05, 0.03-0.1, 0.03-0.08, 0.03-0.06, 0.03-0.05, 4-12, 4-10, 4-8, 5-12, 5-10, 5-8, 6-12, 6-10, or 6-8 wt% or w/v%, for example, or a range between any two of these values. The liquid component of an aqueous composition herein can be an aqueous fluid such as water or aqueous solution, for instance.

Reference herein to an aqueous composition or dry composition can also be with respect to an aqueous system or dry system, respectively. In some aspects, a composition herein can comprise, or be in the form of, a solution, dispersion (e.g., emulsion), mixture, wet cake or wet powder, or dry powder. A solvent of a composition herein can, in some aspects, comprise water and at least about 40% (v/v or w/w) of one or more polar organic solvents, for example. In some aspects, a solvent comprises about, or at least about, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 40-90, 40-80, 40-70, 40-60, 50-90, 50-80, 50-70, 50-60, 60-90, 60-80, 60-70, 70-90, 70-80, 40-70, 40-60, 75-85, or 85-95 v/v% or w/w% of one or more polar organic solvents. The balance of a solvent typically is water only (e.g., a solvent with about 75 v/v% polar organic solvent has about 25 v/v% water), but can optionally comprise (e.g., less than 2, 1, 0.5, or 0.25 v/v%) one or more other liquids aside from a polar organic solvent. A solvent herein can optionally be characterized as an aqueous solvent given its having water. While a solvent herein typically comprises one type of polar organic solvent, two, three, or more polar organic solvents can optionally be included; in such aspects, the polar organic solvent concentration typically is that of the combination of the polar organic solvents. A polar organic solvent in some aspects can be protic. Examples of protic polar organic solvents herein include an alcohol (e.g., methanol, ethanol, isopropanol, 1- propanol, tert-butyl alcohol, n-butanol, iso-butanol), methyl formamide and formamide. Additional examples of protic polar organic solvents herein include n-butanol, ethylene glycol, 2-methoxyethanol, 1-methoxy-2-propanol, glycerol, 1,2-propanediol, and 1,3- propanetriol.

An aqueous composition herein can have a viscosity of about, at least about, or less than about, 1, 5, 10, 100, 200, 300, 400, 500, 600, 700, 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000, 15000, 1-300, 10-300, 25-300, 50-300, 1-250, 10-250, 25-250, 50-250, 1-200, 10-200, 25-200, 50-200, 1-150, 10-150, 25-150, 50-150, 1-100, 10-100, 25-100, or 50-100 centipoise (cps), for example. Viscosity can be as measured with an aqueous composition herein at any temperature between about 3 °C to about 80 °C, for example (e.g., 4-30 °C, 15-30 °C, 15-25 °C). Viscosity typically is as measured at atmospheric pressure (about 760 torr) or a pressure that is ±10% thereof. Viscosity can be measured using a viscometer or rheometer, for example, and can optionally be as measured at a shear rate (rotational shear rate) of about 0.1, 0.5, 1.0, 5, 10, 50, 100, 500, 1000, 0.1-500, 0.1-100, 1.0-500, 1.0-1000, or 1.0-100 s^-1 (1/s), or about 5, 10, 20, 25, 50, 100, 200, or 250 rpm (revolutions per minute), for example. A composition as presently disclosed can have a turbidity of about, or less than about, 1500, 1400, 1300, 1200, 1100, 1000, 900, 800, 700, 600, 500, 400, 300, 280, 260, 240, 220, 200, 190, 180, 170, 160, 150, 140, 130, 120, 110, 100, 90, 80, 70, 60, 50, 45, 40, 35, 30, 25, 20, 18, 16, 14, 12, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 1-250, 1-200, 1-150, 1- 100, 1-50, 1-20, 1-15, 1-10, 1-5, 2-250, 2-200, 2-150, 2-100, 2-50, 2-20, 2-15, 2-10, 2-5, 10-250, 10-200, 10-150, 10-100, 10-50, or 10-20 NTU (nephelometric turbidity units), for example. Any of these NTU values can optionally be with respect to a crosslinked alpha-glucan derivative and solvent ingredients portion of a composition herein. In some aspects, any of these NTU levels is contemplated to be (to persist) for a time (typically beginning from initial preparation) of about, at least about, or up to about, 0.5, 1, 2, 4, 6, 8, 10, 20, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, or 360 days, or 1, 2, or 3 years. Any suitable method can be used to measure turbidity, such as the methodology disclosed in Progress in Filtration and Separation (Edition: 1, Chapter 16.

A crosslinked alpha-glucan derivative herein typically is anionic, typically by virtue of having one or more anionic substitution groups (e.g., anionic organic group, sulfonate group, oxidized group). The charge of a crosslinked alpha-glucan derivative herein can be as it exists when the derivative is in an aqueous composition herein, for example, further taking into account the pH of the aqueous composition (in some aspects, the pH can be 4-10 or 5-9, or any pH as disclosed above). In some aspects, with an aqueous composition that is an aqueous dispersion (e.g., emulsion) of particles of a crosslinked alpha-glucan derivative of the present disclosure, the particles are dispersed through about, or at least about, 30%, 40%, 50%, 60%, 70%, 80%, 85%, 90%, 95%, 98%, 99%, or 100% of the volume of the dispersion. In some aspects, such a level of dispersion (e.g., emulsion) is contemplated to be for a time (typically beginning from initial preparation of the dispersion) of about, at least about, or up to about, 0.5, 1, 2, 4, 6, 8, 10, 20, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, or 360 days, or 1, 2, or 3 years. The temperature of a composition herein comprising a crosslinked alpha-glucan derivative (e.g., aqueous composition) can be about, or up to about, or less than about, 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150, 155, 160, 0-160, 0-150, 0-140, 0-130, 0-120, 0- 110, 0-100, 0-90, 0-80, 0-70, 0-60, 10-160, 10-150, 10-140, 10-130, 10-120, 10-110, 10- 100, 10-90, 10-80, 10-70, 10-60, 50-80, 50-75, 50-70, 50-65, 55-80, 55-75, 55-70, 55- 65, 60-80, 60-75, 60-70, 60-65, 5-50, 15-25, 20-25, 20-30, or 20-40 °C, for example. A composition herein comprising a crosslinked alpha-glucan derivative can, in some aspects, be non-aqueous (e.g., a dry composition). Examples of such embodiments include powders, granules, microcapsules, flakes, or any other form of particulate matter. Other examples include larger compositions such as pellets, bars, kernels, beads, tablets, sticks, or other agglomerates, or ointment or lotion (or any other form herein of a non-aqueous or dry composition). A non-aqueous or dry composition typically has about, or no more than about, 12, 10, 8, 6, 5, 4, 3, 2, 1.5, 1.0, 0.5, 0.25, 0.10, 0.05, or 0.01 wt% water comprised therein. In some aspects (e.g., those directed to laundry or dish washing detergents), a dry composition herein can be provided in a sachet, pouch, water-dispersible composition/carrier (e.g., fiber-containing composition such as a non-woven or other fibrous structure, a sponge or foam, an agglomerate), water-dissolvable composition/carrier (e.g., sheet or film, fiber-containing composition such as a non-woven or other fibrous structure, a sponge or foam, an agglomerate), or any other suitable unit dose form. A composition herein comprising a crosslinked alpha-glucan derivative can, in some aspects, be a detergent composition. Examples of such compositions are disclosed herein as detergents for dishwashing and detergents for fabric care. A composition herein comprising a crosslinked alpha-glucan derivative can, in some aspects, comprise one or more salts such as a sodium salt (e.g., NaCl, Na₂SO₄). Other examples of salts include those having (i) an aluminum, ammonium, barium, calcium, chromium (II or III), copper (I or II), iron (II or III), hydrogen, lead (II), lithium, magnesium, manganese (II or III), mercury (I or II), potassium, silver, sodium strontium, tin (II or IV), or zinc cation, and (ii) an acetate, borate, bromate, bromide, carbonate, chlorate, chloride, chlorite, chromate, cyanamide, cyanide, dichromate, dihydrogen phosphate, ferricyanide, ferrocyanide, fluoride, hydrogen carbonate, hydrogen phosphate, hydrogen sulfate, hydrogen sulfide, hydrogen sulfite, hydride, hydroxide, hypochlorite, iodate, iodide, nitrate, nitride, nitrite, oxalate, oxide, perchlorate, permanganate, peroxide, phosphate, phosphide, phosphite, silicate, stannate, stannite, sulfate, sulfide, sulfite, tartrate, or thiocyanate anion. Thus, any salt having a cation from (i) above and an anion from (ii) above can be in a composition, for example. A salt can be present in an aqueous composition herein at a wt% of about, or at least about, .01, .025, .05, .075, .1, .25, .5, .75, 1.0, 1.25, 1.5, 1.75, 2.0, 2.5, 3.0, 3.5, .01-3.5, .5-3.5, .5- 2.5, or .5-1.5 wt% (such wt% values typically refer to the total concentration of one or more salts), for example. A composition herein comprising a crosslinked alpha-glucan derivative can optionally contain one or more enzymes (active enzymes). Examples of suitable enzymes include proteases, cellulases, hemicellulases, peroxidases, lipolytic enzymes (e.g., metallolipolytic enzymes), xylanases, lipases, phospholipases, esterases (e.g., arylesterase, polyesterase), perhydrolases, cutinases, pectinases, pectate lyases, mannanases, keratinases, reductases, oxidases (e.g., choline oxidase), phenoloxidases, lipoxygenases, ligninases, pullulanases, tannases, pentosanases, malanases, beta- glucanases, arabinosidases, hyaluronidases, chondroitinases, laccases, metalloproteinases, amadoriases, glucoamylases, arabinofuranosidases, phytases, isomerases, transferases, nucleases, and amylases. If an enzyme(s) is included, it can be comprised in a composition herein at about 0.0001-0.1 wt% (e.g., 0.01-0.03 wt%) active enzyme (e.g., calculated as pure enzyme protein), for example. In fabric care or automatic dishwashing applications, an enzyme (e.g., any of the above such as cellulase, protease, amylase, nuclease, and/or lipase) can be present in an aqueous composition in which a fabric or dish is treated (e.g., wash liquor, grey water) at a concentration that is minimally about 0.01-0.1 ppm total enzyme protein, or about 0.1-10 ppb total enzyme protein (e.g., less than 1 ppm), to maximally about 100, 200, 500, 1000, 2000, 3000, 4000, or 5000 ppm total enzyme protein, for example. A crosslinked alpha-glucan derivative and/or a composition comprising such a derivative is biodegradable in some aspects. Such biodegradability can be, for example, as determined by the Carbon Dioxide Evolution Test Method (OECD Guideline 301B, incorporated herein by reference), to be about, at least about, or at most about, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 5-60%, 5-80%, 5-90%, 40-70%, 50-70%, 60-70%, 40-75%, 50-75%, 60-75%, 70-75%, 40-80%, 50-80%, 60-80%, 70-80%, 40-85%, 50-85%, 60-85%, 70-85%, 40- 90%, 50-90%, 60-90%, or 70-90%, or any value between 5% and 90%, after 15, 30, 45, 60, 75, or 90 days of testing. It is contemplated that such biodegradability can be about, at least about, or at most about, 10%, 25%, 50%, 75%, 100%, 150%, 200%, 250%, 500%, 750%, or 1000% higher than the biodegradability of an incumbent material. A composition can comprise one, two, three, four or more different crosslinked alpha-glucan derivatives herein and, optionally, at least one non-crosslinked alpha- glucan derivative (e.g., as disclosed herein). For example, a composition can comprise at least one type of crosslinked alpha-glucan derivative and at least one type of non- crosslinked alpha-glucan derivative; in some aspects, the latter can be (or can be capable of being) a precursor compound of the former. In some aspects, a non- crosslinked alpha-glucan derivative (e.g., precursor compound) is not present. In some aspects, an aqueous composition herein comprising a crosslinked alpha- glucan derivative further comprises at least one cation, and the derivative is bound to the cation. Such binding is typically via ionic bonding. Examples of a cation include one or more hard water cations such as Ca²⁺ and/or Mg²⁺. The binding of a crosslinked alpha- glucan derivative herein to a cation in an aqueous composition/system can act to soften the water (act as a builder) of the aqueous composition/system, for instance. An aqueous composition/system in which a crosslinked alpha-glucan derivative herein can bind to at least one cation can be wash liquor / grey water being used to wash dishware herein (e.g., in an automatic dishwashing machine) or fabric-containing articles herein (e.g., clothes, such as in a laundry machine), or any other aqueous composition/system to which a detergent has been added for washing and/or providing maintenance, for example; such an aqueous composition/system typically can benefit from the ability of the crosslinked alpha-glucan derivative to prevent/reduce negative effects (e.g., scale deposition and/or scum formation) caused by the presence of one or more cations. In some aspects, an aqueous composition/system in which a crosslinked alpha-glucan derivative can bind to at least one cation can be any system disclosed herein in which water or an aqueous solution is circulated, transited, and/or stored (a detergent does not necessarily need to be present); such a system typically can also benefit for the same reasons as disclosed above. Typically, a crosslinked alpha-glucan derivative herein can act as a builder/softener by sequestering/chelating and/or precipitating cations. An aqueous-soluble crosslinked alpha-glucan derivative herein can, in some aspects, bind cations and remain aqueous-soluble. An aqueous-insoluble crosslinked alpha-glucan derivative herein that is dispersed (e.g., stably dispersed) can, in some aspects, bind cations and remain dispersed. The binding (or other interaction, whatever the case may be) between a crosslinked alpha-glucan derivative herein with a cation can prevent/reduce formation (e.g., by about, or at least about 10%, 20%, 30%, 40%, 50%, 60%, 70%, or 80%, as compared to not using the crosslinked alpha-glucan derivative) of undesired insoluble salts (e.g., carbonates such as CaCO₃ or MgCO₃, hydroxides such as Mg(OH)₂ or Ca(OH)₂, sulfates such a CaSO₄) and/or other insoluble compounds (e.g., calcium and/or magnesium salts of fatty acids such as stearate), and/or their deposits (e.g., scale, scum such as soap scum) that can form in aqueous systems having hard water cations. In some aspects, scale can comprise CaCO3, MgCO3, CaSO4, Fe2O3, FeS, and/or FeS2. In addition to those mentioned above, some examples of aqueous systems herein that can be treated with a crosslinked alpha-glucan derivative include those of an industrial setting. Examples of industrial settings herein include those of an energy (e.g., fossil fuel such as petroleum or natural gas), water (e.g., water treatment and/or purification, industrial water, wastewater treatment), agriculture (e.g., grain, fruits/vegetables, fishing, aquaculture, dairy, animal farming, timber, plants), chemical (e.g., pharmaceutical, chemical processing), food processing/manufacturing, mining, or transportation (e.g., fresh water and/or maritime shipping, train or truck container) industry. Further examples of aqueous systems herein that can be treated with a crosslinked alpha-glucan derivative herein include those for water treatment, water storage, and/or other water-bearing system (e.g., piping/conduits, heat exchangers, condensers, filters/filtration systems, storage tanks, water cooling towers, water cooling systems/apparati, pasteurizers, boilers, sprayers, nozzles, ship hull, ballast water). Further examples of aqueous systems herein that can be treated with a crosslinked alpha-glucan derivative herein include those of a medical/dental/healthcare setting (e.g., hospital, clinic, examination room, nursing home; e.g., instrument cleaning), food service setting (e.g., restaurant, commissary kitchen, cafeteria), retail setting (e.g., grocery, soft drink machine/dispenser), hospitality/travel setting (e.g., hotel/motel), sports/recreational setting (e.g., aquatics/tubs, spa), or office/home setting (e.g., bathroom, tub/shower, kitchen, appliances [e.g., laundry machine, automatic dishwashing machine, fridge, freezer], sprinkler system, home/building water piping, water storage tank, water heater). Further examples of aqueous systems herein that can be treated with a crosslinked alpha-glucan derivative herein include those as disclosed in any of U.S. Patent Appl. Publ. Nos.2013/0029884, 2005/0238729, 2010/0298275, 2016/0152495, 2013/0052250, 2015/009891, 2016/0152495, 2017/0044468, 2012/0207699, 2020/0308592, 2024/0199766, or 2024/0150497, or U.S. Patent Nos.4552591, 4925582, 6478972, 6514458, 6395189, 7927496, or 8784659, or Int. Patent Appl. Publ. Nos. WO2022/178073 or WO2022/178075, which are all incorporated herein by reference. In some aspects, an aqueous system that can be treated herein comprises (i) salt water such as seawater, or (ii) an aqueous solution having about 2.0, 2.25, 2.5, 2.75, 3.0, 3.25.3.5, 3.75, 4.0, 2.5-4.0, 2.75-4.0, 3.0-4.0, 2.5-3.5, 2.75-3.5, 3.0-3.5, 3.0- 4.0, or 3.0-3.5 wt% of one or a combination of salts (e.g., including at least NaCl). In some aspects, a crosslinked alpha-glucan derivative can form a complex with a hard water salt herein (e.g., a carbonate such as CaCO3). Such a complex can, for example, comprise a hard water salt that is enveloped/covered (e.g., 100%, or at least 80%, 85%, 90%, 95%, 98%, or 99% enveloped/covered) by the crosslinked alpha- glucan derivative. Such a complex typically is water-insoluble; because of this feature, such a complex can be readily removed from an aqueous composition. Thus, further disclosed herein is a method comprising treating an aqueous composition having at least one hard water salt (e.g., a carbonate such as CaCO3 or MgCO3, a hydroxide such as Ca(OH)₂ or Mg(OH)₂, a sulfate such a CaSO₄) with at least one crosslinked alpha- glucan derivative herein, where the treatment results in the formation of a water- insoluble complex comprising the hard water salt and the crosslinked alpha-glucan derivative. Such a water-insoluble complex can be stably dispersed or stably dispersible in some aspects. This method can optionally further comprise removing all or most of the water-insoluble complexes (that formed during the treatment step) from the aqueous composition. To the extent that this method removes a water-insoluble hard water salt, such a method can optionally be considered as a flocculation method. A water-insoluble complex herein comprising at least one crosslinked alpha-glucan derivative and at least one hard water salt can be used as an ingredient in various products, such as a paper product. Thus, a product such as paper is disclosed herein comprising a complex that comprises a crosslinked alpha-glucan derivative and a hard water salt. A composition/product comprising at least one crosslinked alpha-glucan derivative herein, such as an aqueous composition or a non-aqueous composition, can be in the form of a household care product, personal care product, industrial product, ingestible product (e.g., food product), medical product, or pharmaceutical product, for example, such as described in any of U.S. Patent Appl. Publ. Nos.2018/0022834, 2018/0237816, 2018/0230241, 20180079832, 2016/0311935, 2016/0304629, 2015/0232785, 2015/0368594, 2015/0368595, 2016/0122445, 2019/0202942, or 2019/0309096, or International Patent Appl. Publ. No. WO2016/133734, which are all incorporated herein by reference. In some aspects, a composition can comprise at least one component/ingredient of a household care product, personal care product, industrial product, medical product, pharmaceutical product, or ingestible product (e.g., food product) as disclosed in any of the foregoing publications and/or as presently disclosed.

The present disclosure also concerns a method of treating a material. This method typically comprises contacting a material with an aqueous composition comprising at least one crosslinked alpha-glucan derivative as disclosed herein. A material contacted with an aqueous composition in a contacting method herein can comprise a fabric in some aspects. A fabric herein can comprise natural fibers, synthetic fibers, semi-synthetic fibers, or any combination thereof. A semi-synthetic fiber herein is produced using naturally occurring material that has been chemically derivatized, an example of which is rayon. Non-limiting examples of fabric types herein include fabrics made of (i) cellulosic fibers such as cotton (e.g., broadcloth, canvas, chambray, chenille, chintz, corduroy, cretonne, damask, denim, flannel, gingham, jacquard, knit, matelassé, oxford, percale, poplin, plissé, sateen, seersucker, sheers, terry cloth, twill, velvet), rayon (e.g., viscose, modal, lyocell), linen, and Tencel^®; (ii) proteinaceous fibers such as silk, wool and related mammalian fibers; (iii) synthetic fibers such as polyester, acrylic, nylon, and the like; (iv) long vegetable fibers from jute, flax, ramie, coir, kapok, sisal, henequen, abaca, hemp and sunn; and (v) any combination of a fabric of (i)-(iv). Fabric comprising a combination of fiber types (e.g., natural and synthetic) include those with both a cotton fiber and polyester, for example. Materials/articles containing one or more fabrics herein include, for example, clothing, curtains, drapes, upholstery, carpeting, bed linens, bath linens, tablecloths, sleeping bags, tents, car interiors, etc. Other materials comprising natural and/or synthetic fibers include, for example, non-woven fabrics, paddings, paper, and foams. An aqueous composition that is contacted with a fabric can be, for example, a fabric care composition (e.g., laundry detergent, fabric softener). Thus, a treatment method in certain embodiments can be considered a fabric care method or laundry method if employing a fabric care composition therein. A fabric care composition herein is contemplated to effect one or more of the following fabric care benefits (i.e., surface substantive effects): wrinkle removal, wrinkle reduction, wrinkle resistance, fabric wear reduction, fabric wear resistance, fabric pilling reduction, extended fabric life, fabric color maintenance, fabric color fading reduction, reduced dye transfer, fabric color restoration, fabric soiling reduction, fabric soil release, fabric shape retention, fabric smoothness enhancement, anti-redeposition of soil on fabric, anti-greying of laundry, improved fabric hand/handle, and/or fabric shrinkage reduction. Examples of conditions (e.g., time, temperature, wash/rinse volumes) for conducting a fabric care method or laundry method herein are disclosed in WO1997/003161 and U.S. Patent Nos.4794661, 4580421 and 5945394, which are incorporated herein by reference. In other examples, a material comprising fabric can be contacted with an aqueous composition herein: (i) for at least about 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, or 120 minutes; (ii) at a temperature of at least about 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, or 95 °C (e.g., for laundry wash or rinse: a “cold” temperature of about 15-30 °C, a “warm” temperature of about 30-50 °C, a “hot” temperature of about 50-95 °C); (iii) at a pH of about 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 (e.g., pH range of about 2-12, or about 3-11); (iv) at a salt (e.g., NaCl) concentration of at least about 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, or 4.0 wt%; or any combination of (i)-(iv). The contacting step in a fabric care method or laundry method can comprise any of washing, soaking, and/or rinsing steps, for example. Contacting a material or fabric in still further embodiments can be performed by any means known in the art, such as dissolving, mixing, shaking, spraying, treating, immersing, flushing, pouring on or in, combining, painting, coating, applying, affixing to, and/or communicating an effective amount of a crosslinked alpha-glucan derivative herein with the fabric or material. In still further embodiments, contacting may be used to treat a fabric to provide a surface substantive effect. As used herein, the term “fabric hand” or “handle” refers to a person’s tactile sensory response towards fabric which may be physical, physiological, psychological, social or any combination thereof. In one embodiment, the fabric hand may be measured using a PhabrOmeter^® System for measuring relative hand value (available from Nu Cybertek, Inc. Davis, CA) (American Association of Textile Chemists and Colorists [AATCC test method “202-2012, Relative Hand Value of Textiles: Instrumental Method”]). In some aspects of treating a material comprising fabric, a crosslinked alpha- glucan derivative component of the aqueous composition can adsorb to the fabric. This feature is believed to render a crosslinked alpha-glucan derivative herein useful as anti- redeposition agents and/or anti-greying agents in fabric care compositions disclosed (in addition to their viscosity-modifying and/or builder effects). An anti-redeposition agent or anti-greying agent herein helps keep soil from redepositing onto clothing in wash water after the soil has been removed. It is further contemplated that adsorption of a crosslinked alpha-glucan derivative herein to a fabric enhances mechanical properties of the fabric in some aspects. Adsorption of a crosslinked alpha-glucan derivative to a fabric herein can be measured using a colorimetric technique (e.g., Dubois et al., 1956, Anal. Chem.28:350- 356; Zemljič et al., 2006, Lenzinger Berichte 85:68-76; both incorporated herein by reference), for example, or any other method known in the art. Other materials that can be contacted in the above treatment method include surfaces that can be treated with a dish detergent (e.g., automatic dishwashing detergent or hand dish detergent). Examples of such materials include surfaces of dishes, glasses, pots, pans, baking dishes, utensils and flatware made from ceramic material, china, metal, glass, plastic (e.g., polyethylene, polypropylene, polystyrene, melamine, etc.) and wood (collectively referred to herein as “tableware”). Thus, the treatment method in certain embodiments can be considered a dishwashing method or tableware washing method, for example. Other surfaces that can be contacted in a dishwashing method include those of internal dishwashing machine components such as of a washing chamber/compartment, piping/blades, pump(s), racks/holders, and sensors. Examples of conditions (e.g., time, temperature, wash volume) for conducting a dishwashing or tableware washing method herein are disclosed herein and in U.S. Patent No.8575083 and U.S. Pat. Appl. Publ. No.2017/0044468, which are incorporated herein by reference. In some aspects, a tableware article can be contacted with an aqueous composition herein under a suitable set of conditions such as any of those disclosed above with regard to contacting a fabric-comprising material. Other materials that can be contacted in the above treatment method include oral surfaces such as any soft or hard surface within the oral cavity including surfaces of the tongue, hard and soft palate, buccal mucosa, gums and dental surfaces (e.g., natural tooth or a hard surface of artificial dentition such as a crown, cap, filling, bridge, denture, or dental implant). Thus, a treatment method in certain embodiments can be considered an oral care method or dental care method, for example. Conditions (e.g., time, temperature) for contacting an oral surface with an aqueous composition herein should be suitable for the intended purpose of making such contact. Other surfaces that can be contacted in a treatment method also include a surface of the integumentary system such as skin, hair or nails. Thus, some aspects of the present disclosure concern material (e.g., fabric, or a fiber-comprising product as disclosed herein) that comprises a crosslinked alpha-glucan derivative herein. Such material can be produced following a material treatment method as disclosed herein, for example. A material may comprise a crosslinked alpha-glucan derivative in some aspects if the crosslinked alpha-glucan derivative is adsorbed to, or otherwise in contact with, the surface of the material. Some aspects of a method of treating a material herein further comprise a drying step, in which a material is dried after being contacted with the aqueous composition. A drying step can be performed directly after the contacting step, or following one or more additional steps that might follow the contacting step (e.g., drying of fabric or tableware after being rinsed, in water for example, following a wash in an aqueous composition herein). Drying can be performed by any of several means known in the art, such as air drying (e.g., ~20-25 °C), or at a temperature of at least about 30, 40, 50, 60, 70, 80, 90, 100, 120, 140, 160, 170, 175, 180, or 200 °C, for example. A material that has been dried herein typically has less than 3, 2, 1, 0.5, or 0.1 wt% water comprised therein. Fabric is a preferred material for conducting an optional drying step. An aqueous composition used in a treatment method herein can be any aqueous composition disclosed herein. Examples of aqueous compositions include detergents (e.g., laundry detergent or dish detergent), fabric softeners, and water-containing dentifrices such as toothpaste. A hard surface that is washed or treated in a washing/treating composition comprising an anti-deposition detergent composition herein can have reduced filming, spotting, haze, or other deposition. A washing/treating composition in some aspects can be a wash liquor (grey water) to which an anti-deposition detergent composition has been added (e.g., the detergent can be provided in a concentrated form and diluted into a washing/treating composition when washing is to be performed). A washing/treating composition herein can be that used in an automatic dishwasher or a laundry machine, for example; features of such a washing/treating composition can be as disclosed herein for dishwashing and fabric care compositions. In some aspects, a washing/treating composition comprises at least one cation, and a crosslinked alpha-glucan derivative is bound to the cation; this aspect can have any feature disclosed herein with respect to cation binding. An anti-deposition detergent composition can be formulated according to any automatic dishwashing or fabric care composition as disclosed herein or in an incorporated reference, for example, and/or contain any disclosed ingredient (e.g., surfactant, enzyme, etc.), and/or be in any form disclosed herein (e.g., powder, flakes, liquid, unit dose, etc.). The amount of a crosslinked alpha-glucan derivative herein can be about, or at least about 4, 5, 6, 7, 8, 9, 10, 11, 12, 4-12, 4-10, 4-8, 5-12, 5-10, 5-8, 6- 12, 6-10, or 6-8 wt%, for example. In some aspects, an anti-deposition detergent composition has each of the ingredients listed in Table A below; the amount (wt%) of each ingredient in such a composition can be within (plus/minus) 5%, 10%, 15%, 5-10%, or 5-15% of the respective value in Table A. Table A

Some aspects of the present disclosure concern a method of washing/cleaning or treating a hard surface. Such a washing/cleaning or treating method can comprise: (a) contacting the hard surface with a washing/treating composition that comprises an anti-deposition detergent composition herein, and (b) removing all of, or a portion of, the washing/treating composition from the hard surface (e.g., by rinsing with water with, or without, a rinse aid [water/liquid-removing aid] and/or added salts); thereby washing/cleaning or treating the hard surface, wherein the washed/cleaned/treated hard surface has reduced filming, spotting, haze, or other deposition. Such a method can include any condition (e.g., temperature, pH, time, salt/buffer, etc.) (e.g., those for automatic dishwashing machine) disclosed herein, for example, that are suitable for washing, treating a material/surface, and/or cation binding. A hard surface treated by a washing/cleaning method can be any hard surface, such as a hard surface of, or that is associated/interacting with, an aqueous composition or system as disclosed herein. Examples of a hard surface comprise or consist of glass, plastic (e.g., styrene-acrylonitrile, polystyrene, polypropylene, polyethylene, melamine), ceramic, porcelain, metal (e.g., steel, stainless steel, aluminum), or stone (e.g., marble, granite); any of these surfaces can be of a piece of dishware disclosed herein, for example. A hard surface in some aspects can be a surface found within (e.g., body/housing of) an automatic dishwasher, laundry machine, or similar device, and/or an internal component thereof (e.g., piping, sprayer, nozzle, rack, agitator). In some aspects in which a washing/cleaning method is performed in an automatic dishwasher, a wash cycle can comprise the following sequential periods: (i) optionally at least one pre-wash period during which water (e.g., at ~40-70, 45-70, 50- 70, or 60-70 °C) is circulated (e.g., for about 3-15, 3-10, or 3-6 minutes) to loosen food material on dishware; (ii) a main wash period during which an anti-deposition detergent composition herein (e.g., about 10-3010-25, 10-20, 15-30, 15-25, or 15-20 g, dry weight) is added (e.g., via automatic dispenser) to water (e.g., at ~40-70, 45-70, or 50- 70 °C) (e.g., about 1-2.5, 1-2, 1.5-2.5, or 1.5-2 gallons) for circulation (thereby rendering a washing composition) for a suitable amount of time (e.g., about 3-20, 3-15, 3-10, 5-20, 5-15, or 5-10 minutes); (iii) at least one rinse period during which water (e.g., at ~40-70, 45-70, 50-70, or 60-70 °C) is circulated (e.g., for about 3-15, 3-10, or 3-6 minutes); and (iv) optionally a drying period. After each of periods (ii) and (iii) (and optionally after optional period [i]) of a wash cycle, the circulated liquid typically is removed, such as by pumping and/or draining. A washing/cleaning method herein can be performed to wash dishware (e.g., using an automatic dishwasher, or manual/hand dishwashing). Dishware, for example, can be as disclosed herein or in U.S. Patent No.8575083 or U.S. Pat. Appl. Publ. No. 2017/0044468, which are incorporated herein by reference. Dishware can include, for example, plates, cups, glasses, bowls, pots, cutlery, spoons, knives, forks, serving utensils, ceramics, plastics, cutting boards, china, chinaware, glassware, tableware, utensilware, and kitchenware. A hard surface washed by a washing/cleaning method herein has reduced filming, spotting, haze and/or other deposition. In some aspects, such reduction is by about, or at least about 10%, 20%, 30%, 40%, 50%, 60%, 70%, or 80% as compared to what would be observed with a washing/cleaning method using a detergent composition that does not have a crosslinked alpha-glucan derivative herein; all other features of the comparative washing/cleaning method can otherwise be the same. Filming, spotting, haze, and related depositions typically contain one or more insoluble salts (e.g., carbonates such as CaCO3 or MgCO3, hydroxides such as Mg(OH)2 or Ca(OH)2, sulfates such a CaSO₄) and/or other insoluble compounds (e.g., calcium and/or magnesium salts of fatty acids such as stearate). Filming and/or spotting can optionally also be referred to as deposits of scale and/or scum (e.g., soap scum). A rinse aid can optionally be used during or after removing a washing/treating composition from a hard surface, such as in an automatic dishwashing process herein. A rinse aid generally is intended to remove remaining water/liquid from a hard surface, and thus can optionally be referred to as a water/liquid-removing aid. In this vein, a rinse aid can improve removal, from a hard surface, of water/liquid containing any dissolved and/or dispersed compounds such as minerals and/or crosslinked alpha- glucan derivative-containing complexes. A rinse aid / water/liquid-removing aid in some aspects can be as disclosed in any of U.S. Patent Nos.6630440, 5739099, 5516452, 8685911, 9567551, or 11118140, which are each incorporated herein by reference. A rinse aid in some aspects can comprise an oxoalcohol (fatty alcohol alkoxylate); an example of such a rinse aid is GENAPOL EP 2564 (CAS no.120313-48-6). The present disclosure also concerns a method of preparing an aqueous composition having increased builder capacity. This method comprises, for instance, contacting at least one crosslinked alpha-glucan derivative as disclosed herein with an aqueous composition, wherein the builder capacity of the aqueous composition is increased by the derivative as compared to the builder capacity of the aqueous composition as it existed before the contacting step. Such a method can optionally be characterized as a water (or any other aqueous composition) softening method. An aqueous composition in this method can be any aqueous composition as disclosed herein, for example, such as a household care product, personal care product, industrial product, pharmaceutical product, or food product. Examples of suitable household care products include household care or industrial care products such as laundry detergent or fabric softener, and automatic dishwashing detergent. Examples of suitable personal care items include hair care products (e.g. shampoos, conditioners), dentifrice compositions (e.g., toothpaste, mouthwash), and skin care products (e.g., hand or body soap, lotion, cosmetics). In some aspects, an aqueous composition in this method is a detergent and/or surfactant composition. Such a composition herein can comprise at least one detergent/surfactant ingredient, such as any of the present disclosure, at about 0.01-10 wt% (e.g., about 0.05-5.0 wt% or about 0.1-2.0 wt%), for example. A skilled artisan would recognize all the various products disclosed herein that constitute examples of detergent/surfactant-comprising compositions such as certain household care products (e.g., laundry detergent, dishwashing detergent) and personal care products (e.g., hand/body soap, dentifrices), particularly those used in cleaning applications. Contacting an aqueous composition with one or more crosslinked alpha-glucan derivatives in some aspects can increase the builder capacity of the aqueous composition. This increase can be by about, or at least about 1%, 5%, 10%, 25%, 50%, 100%, 500%, or 1000% (or any integer between 1% and 1000%), for example, compared to the builder capacity of the aqueous composition before the contacting step. The degree of increased builder capacity achieved can be measured following any number of methods. For example, increased builder capacity effected by a crosslinked alpha-glucan derivative herein can be estimated by determining the extent to which the derivative supplies alkalinity to an aqueous composition, or buffers an aqueous composition to maintain alkalinity. As another example, increased builder capacity effected by a crosslinked alpha-glucan derivative herein can be estimated by determining the extent to which the derivative reduces hardness in an aqueous composition (by sequestering or chelating hard water cations) and/or helps to remove soil in suspension (this feature typically applies to fabric care compositions). As other examples, increased builder capacity can be determined following methodology (e.g., calcium dispersing capacity, NTU assay, film reduction assay) disclosed in the below Examples and/or in U.S. Pat. Appl. Publ. Nos.2018/0022834, 2024/0199766, or 2024/0150497, or Int. Patent Appl. Publ. Nos. WO2022/178073 or WO2022/178075, which are incorporated herein by reference.

EXAMPLES The present disclosure is further exemplified in the following Examples. It should be understood that these Examples, while indicating certain aspects herein, are given by way of illustration only. From the above discussion and these Examples, one skilled in the art can ascertain the essential characteristics of the disclosed embodiments, and without departing from the spirit and scope thereof, can make various changes and modifications to adapt the disclosed embodiments to various uses and conditions. Materials/Methods Representative Preparation of Alpha-1,3-Glucan: Alpha-1,3-glucan with ~100% alpha-1,3 glycosidic linkages can be synthesized, for example, following the procedures disclosed in U.S. Appl. Publ. No.2014/0179913 (see Example 12 therein, for example), which is incorporated herein by reference. As another example, a slurry of alpha-1,3-glucan with ~100% alpha-1,3 glycosidic linkages was prepared from an aqueous solution (0.5 L) containing Streptococcus salivarius gtfJ enzyme (100 unit/L) as described in U.S. Patent Appl. Publ. No. 2013/0244288 (incorporated herein by reference), sucrose (100 g/L), potassium phosphate buffer (10 mM), and FermaSure® antimicrobial agent (100 ppm) adjusted to pH 5.5. The resulting enzyme reaction was maintained at 20-25 °C for 24 hours. A slurry was formed since the alpha-1,3-glucan synthesized in the reaction was aqueous- insoluble. The alpha-1,3-glucan solids were then collected using a Buchner funnel fitted with a 325-mesh screen over 40-micrometer filter paper. Representative Preparation of Alpha-1,6-Glucan with Alpha-1,2 Branching Each alpha-1,2-branched alpha-1,6-glucan listed below comprises a 100%-alpha- 1,6-linked backbone upon which pendant (single) glucosyls have been linked via alpha- 1,2 linkages; thus, each pendant glucosyl is attached to the backbone via an alpha-1,2 linkage/branch-point. An example of an alpha-1,2-branched alpha-1,6-glucan herein has 40% alpha-1,2-branching and 60% alpha-1,6 linkages. In this example, 60% of all the linkages of the alpha-glucan are alpha-1,6 linkages that are in the backbone, while the balance of the linkages (40%) are alpha-1,2 linkages to pendant glucosyls along the backbone. Methods to prepare alpha-1,6-glucan containing various amounts of alpha-1,2 branching are disclosed in U.S. Appl. Publ. No.2018/0282385, which is incorporated herein by reference. Reaction parameters such as sucrose concentration, temperature, and pH can be adjusted to provide alpha-1,6-glucan having various levels of alpha-1,2- branching and molecular weight. A representative procedure for the preparation of alpha-1,2-branched alpha-1,6-glucan is provided below (containing 19% alpha-1,2- branching [i.e., 19% alpha-1,2 linkages] and 81% alpha-1,6 linkages). The 1D ¹H-NMR spectrum was used to quantify glycosidic linkage distribution. Additional samples of alpha-1,6-glucan with alpha-1,2-branching were prepared similarly. For example, one sample contained 32% alpha-1,2-branching and 68% alpha-1,6 linkages, and another contained 10% alpha-1,2-branching and 90% alpha-1,6 linkages. Soluble alpha-1,6-glucan with about 19% alpha-1,2 branching was prepared using stepwise combination of glucosyltransferase (dextransucrase) GTF8117 and alpha-1,2 branching enzyme GTFJ18T1, according to the following procedure. A reaction mixture (2 L) comprised of sucrose (450 g/L), GTF8117 (9.4 U/mL), and 50 mM sodium acetate was adjusted to pH 5.5 and stirred at 47 °C. Aliquots (0.2-1 mL) were withdrawn at predetermined times and quenched by heating at 90 °C for 15 minutes. The resulting heat-treated aliquots were passed through a 0.45-µm filter. The flow- through was analyzed by HPLC to determine the concentration of sucrose, glucose, fructose, leucrose, oligosaccharides and polysaccharides. After 23.5 hours, the reaction mixture was heated to 90 °C for 30 minutes. An aliquot of the heat-treated reaction mixture was passed through a 0.45-µm filter and the flow-through was analyzed for soluble mono/disaccharides, oligosaccharides, and polysaccharides. A major product was linear dextran (i.e., 100% alpha-1,6 linkages) with a DPw of 93. A second reaction mixture was prepared by adding 238.2 g of sucrose and 210 mL of alpha-1,2-branching enzyme GTFJ18T1 (5.0 U/mL) to the leftover heat-treated reaction mixture that was obtained from the GTF8117 reaction described immediately above. The mixture was stirred at 30 °C with a volume of ~2.2 L. Aliquots (0.2-1 mL) were withdrawn at predetermined times and quenched by heating at 90 °C for 15 minutes. The resulting heat-treated aliquots were passed through a 0.45-µm filter. The flow-through was analyzed by HPLC to determine the concentration of sucrose, glucose, fructose, leucrose, oligosaccharides and polysaccharides. After 95 hours, the reaction mixture was heated to 90 °C for 30 minutes. An aliquot of the heat-treated reaction mixture was passed through a 0.45-µm filter and the flow-through was analyzed for soluble mono/disaccharides, oligosaccharides, and polysaccharides. Leftover heat- treated mixture was centrifuged using 1-L centrifugation bottles. The supernatant was collected and cleaned more than 200-fold using an ultrafiltration system with 1- or 5-kDa MWCO cassettes and deionized water. The cleaned oligo/polysaccharide product solution was dried. Dry sample was then analyzed by ¹H-NMR spectroscopy to determine the anomeric linkages of the oligosaccharides and polysaccharides. Various water-soluble alpha-1,2-branched alpha-1,6-glucans can be made following the above (or similar) enzymatic reaction strategy, for example. This type of alpha-glucan material can also be produced according to methodology disclosed in U.S. Pat. Appl. Publ. No.2018/0282385, for example, which is incorporated herein by reference. Examples of different alpha-1,2-branched alpha-1,6-glucans that have been produced are listed in Table 1. In each of these alpha-glucans, the alpha-1,6-glucan backbone (from which there are alpha-1,2 branches) has 100% alpha-1,6 glycosidic linkages; the listed molecular weight is that of the alpha-1,6-glucan backbone. Each alpha-1,2-branch consists of a single (pendant) glucose unit. Table 1 Alpha-1,2-Branched Alpha-1,6-Glucan

Any alpha-1,2-branched alpha-1,6-glucan as disclosed herein (e.g., Table 1) can be used as a substrate for a derivatization procedure as described below, for example. Representative Preparation of Carboxymethyl Alpha-1,6-Glucan A three-neck, 2-L round-bottom flask equipped with an overhead stirrer was charged with 267 g of a 37.5 wt% alpha-1,6-glucan solution (53 kDa, 6.4% alpha-1,2- branching). To the solution was added 50 wt% sodium hydroxide solution via an addition funnel over 15 minutes (199 g) with stirring. To this stirring solution was added chloroacetic acid solution (116 g dissolved in 77 g water) via an addition funnel over 30 minutes. This solution was heated to 55 °C under nitrogen for 5 hours. The resulting amber solution was cooled and neutralized to pH 7 with 18 wt% HCl. The resulting light yellow solution was diluted to 3 L, and purified by diafiltration (3X MWCO 5-kDa PES membrane, ~9 L of water was passed through). The solution was concentrated with a rotary evaporator and freeze-dried to yield a white powder. The degree of substitution of the thus prepared carboxymethyl alpha-1,6-glucan product was determined by ¹H-NMR analysis to be 0.51. Representative Preparation of Carboxymethyl Alpha-1,3-Glucan A 4-neck, 2 L round bottom flask containing a metal/mechanical stir rod, thermocouple, addition funnel and condenser with N₂ inlet on top, was charged with alpha-1,3-glucan (DPw ~650, 110 g) and water (110 g). The mixture was set at room temperature overnight. Ethanol (220 g, 92 wt%) was added at room temperature. The mixture was stirred at 200 rpm and sodium hydroxide (191.1 g, 50 wt% solution) was added over a 20 minute period (25 to 37 °C). The white slurry was stirred for an additional 10 minutes. A solution containing 112.2 g of chloroacetic acid in 50 g of 92 wt% ethanol was added over a 20 minute period (35 to 55 °C). The white slurry was heated by a heating mantel for 3 hours at 58-60 °C. The reaction mixture was cooled to 45 °C and sodium hydroxide (108.6 g, 50 wt% solution) was added over 10 minutes, followed by a solution containing 64.13 g of chloroacetic acid in 35 g of 92 wt% ethanol. The resulting mixture was heated for 2 hours at 58-65 °C. A large lump formed. The liquid (~500 mL) from the reaction mixture was decanted. Methanol (400 mL) was added and the pH of the mixture was adjusted to about 7 by adding HCl (18.5 wt%, 13.5 g). The liquid was decanted. The resulting solid was washed with methanol (90 wt%, 700 mL), twice with methanol (80 wt%, 700 mL each), and filtered to give a solid, which was dried under full vacuum overnight to give 148.5 g of desired product. The degree of substitution of the thus prepared carboxymethyl alpha-1,3-glucan product was determined by ¹H-NMR analysis to be 0.91. Representative Preparation of Oxidized Carboxymethyl Starch A 4-neck, 500-mL round-bottom flask equipped with a stir rod, thermocouple, addition funnel and air inlet was charged with starch (20 g, Sigma-Aldrich cat. no. S9765, soluble starch). To this was added sodium hydroxide solution (34 g of 50 wt% NaOH solution). This solution was stirred overnight. The solution was heated in a 50 °C oil bath, and monochloroacetic acid (MCA) solution was added (16 gram of MCA in 8 gram of DI-water) via the addition funnel. The solution was then heated in a 65 °C oil bath for 2 hours. The solution was cooled down to room temperature and neutralized with 18 wt% HCl (13 mL). A 10-mL sample of this reaction was harvested and the carboxymethyl starch product thereof was purified in methanol. The carboxymethyl DoS of this product was determined by ¹³C-NMR analysis to be 0.62. TEMPO (0.1 gram) and NaBr (1.0 gram) were added to the above reaction. NaClO (10-15 wt%, 100 mL) was then added dropwise within 0.5 hour. NaOH (2 N, 17 mL) was used to adjust pH. The final pH was 9.9. The thus prepared oxidation reaction was stirred at room temperature for 1.5 hours. The crude material was diluted in 1 gallon of DI-water, stirred at room temperature for 1 hour, filtered, purified by ultrafiltration (PELLICON MINI with 5 kDa MWCO cassettes), and freeze-dried to render 21.2 g of oxidized product. The total carboxy DoS of the oxidized carboxymethyl starch product as contributed by individual carboxymethyl groups and individual carboxy groups was determined by ¹³C-NMR analysis to be 0.67. Its Mw was determined by SEC to be 53 kDa. Representative Synthesis of Oxidized Carboxymethyl Dextran A 4-neck, 500-mL round-bottom flask equipped with a stir rod, thermocouple, addition funnel and air inlet was charged with dextran (20 g) produced using glucosyltransferase (GTF) 0768 as described in U.S. Patent Appl. Publ. No. 2016/0122445 (incorporated herein by reference). To this was added sodium hydroxide solution (34 g of 50 wt% NaOH solution). This solution was stirred overnight. The solution was heated in a 50 °C oil bath, and monochloroacetic acid (MCA) solution was added (16 gram of MCA in 8 gram of DI-water) via the addition funnel. The solution was then heated in a 65 °C oil bath for 2 hours. The solution was cooled down to room temperature and neutralized with 18 wt% HCl (17 mL). A 10-mL sample of this reaction was harvested and the carboxymethyl dextran product thereof (denoted herein as “ADW36-Comparative”) was purified in methanol. The carboxymethyl DoS of this product was determined by ¹³C-NMR analysis to be 0.46. TEMPO (0.1 gram) and NaBr (1.0 gram) were added to the above reaction. NaClO (10-15 wt%, 90 mL) was added dropwise within 0.5 hour. NaOH (2 N, 15 mL) was used to adjust pH. The final pH was 9.6. The thus prepared oxidation reaction was stirred at room temperature for 1.5 hours. The crude material was diluted in 1 gallon of DI-water, stirred at room temperature for 1 hour, filtered, purified by ultrafiltration (PELLICON MINI with 5 kDa MWCO cassettes), and freeze-dried to render 17.8 g of oxidized product. The total carboxy DoS of the oxidized carboxymethyl dextran product (denoted herein as “ADW36”) as contributed by individual carboxymethyl groups and individual carboxy groups was determined by ¹³C-NMR analysis to be 0.51. Its Mw was determined by SEC to be 49 kDa. Thus, the ADW36 product was found to be further substituted with carboxy groups, at least, as compared to its parent compound (ADW36- Comparative). Representative Synthesis of Oxidized Carboxymethyl Dextran A 4-neck, 500-mL round-bottom flask equipped with a stir rod, thermocouple, addition funnel, and air inlet was charged with dextran (30 g, Sigma-Aldrich cat. no. D5376, Leuconostoc mesenteroides, Mw 1.5-2.8 million Da) and DI-water (120 mL). To this was added sodium hydroxide solution (51 g of 50 wt% NaOH solution). This solution was stirred overnight. The solution was heated in a 50 °C oil bath, and monochloroacetic acid (MCA) solution was added (24 gram of MCA in 12 gram of DI- water) via the addition funnel. The solution was then heated in a 65 °C oil bath for 2 hours. The solution was cooled down to room temperature and neutralized with 18 wt% HCl (23 mL). A 10-mL sample of this reaction was harvested and the carboxymethyl dextran product thereof (denoted herein as “ADW39-Comparative”) was purified in methanol. The carboxymethyl DoS of this product was determined by ¹³C NMR analysis to be 0.58. TEMPO (0.15 gram) and NaBr (1.5 gram) were added to the above reaction. NaClO (10-15 wt%, 135 mL) was added dropwise within 0.5 hour. NaOH (2 N, 20 mL) was used to adjust pH. The final pH was 9.6. The thus prepared oxidation reaction was stirred at room temperature for 1.5 hrs. The crude material was diluted in 1 gallon of DI- water, stirred at room temperature for 1 hour, filtered, purified by ultrafiltration (PELLICON MINI with 5 KDa MWCO cassettes), and freeze-dried to render 32.5 g of oxidized product. The total carboxy DoS of the oxidized carboxymethyl dextran product (denoted herein as “ADW39”) as contributed by individual carboxymethyl groups and individual carboxy groups was determined by ¹³C-NMR analysis to be 0.67. Its Mw was determined by SEC to be 27 kDa. Thus, the ADW39 product was found to be further substituted with carboxy groups, at least, as compared to its parent compound (ADW39- Comparative). Representative Synthesis of Oxidized Cyanoethyl Carboxyethyl Alpha-1,3-Glucan A 4-neck, 1-L round-bottom flask containing a mechanical stir rod, thermocouple and addition funnel was charged with 260 g of alpha-1,3-glucan (DPw 800) wet cake (38.5 wt% glucan) and 550 g of DI-water. The mixture was stirred at room temperature while 64 g of 50 wt% sodium hydroxide solution was added over a 15-minute period. Acrylonitrile (64 g) was then added slowly at 25 °C in 10 minutes. The thus prepared cyanoethylation reaction was stirred at room temperature for 3.5 hrs. HCl (18.5 wt%, 135 g) was then added to bring the pH of the reaction to about 7. The crude product was precipitated and washed in methanol to render 124 gram of cyanoethyl carboxyethyl alpha-1,3-glucan (denoted herein as “ADW7-Comparative”). The DoS of this product with cyanoethyl and carboxyethyl groups was determined by ¹³C NMR analysis to be 0.90 and 0.12, respectively. Carboxyethyl groups were formed in the above reaction via hydrolysis of some cyano groups due to the basic aqueous conditions. A 4-neck, 250-mL round-bottom flask equipped with a stir rod, thermocouple, addition funnel, and air inlet was charged with an aqueous solution of the above- prepared cyanoethyl carboxyethyl alpha-1,3-glucan product (5 g, ADW7-Comparative) in 50 mL DI-water. TEMPO (0.1 gram) and NaBr (1 gram) were then added to the solution. To this stirring solution, NaClO (10-15 wt%, 25 mL) was added dropwise within 0.5 hour. NaOH (2 N, 13 mL) was then used to adjust the pH of the solution to 10.5. The thus prepared oxidation reaction was stirred at room temperature for three hours. The crude material was then diluted in 1 gallon of DI-water, stirred at room temperature for 6 hours, filtered, purified by ultrafiltration (PELLICON MINI with 5 KDa MWCO cassettes), and freeze-dried to render 3.7 g of oxidized product. The DoS of the oxidized product (denoted herein as “ADW7”) was determined by ¹³C-NMR analysis to be 0.61/0.61 (cyanoethyl/carboxy) (carboxy DoS reported as a contributed by individual carboxyethyl groups and individual carboxy groups). Its Mw was determined by SEC to be 37 kDa. Example 1 Summary of Example 1 In this Example, biopolymers are described that have been crosslinked in a particular manner, leading to a surprising and unexpected benefit in the application of automatic dishwashing (ADW) and particularly a shine benefit (i.e., a form of detergent builder activity is provided). For example, no calcium carbonate (CaCO3) and magnesium carbonate (MgCO3) were deposited on kitchenware in the dishwasher, thereby creating an advanced level of cleaned kitchenware and vision of shine. Calcium and magnesium ions were introduced via tap water having a relatively high hardness (°D, which typically indicates the level of Ca²⁺ and Mg²⁺). Alpha-1,3-glucan and alpha-1,2-branched alpha-1,6-glucan were used in this work, both with a weight-average degree of polymerization (DPw) of about 800 and 1600. These glucan polymers were functionalized with negatively charged groups (e.g., carboxyalkyl- or sulfonate-comprising organic groups), leading to anionic polymers; alternatively or additionally, the polymers could be oxidized to add negative charge. The crosslinker used to further boost performance of the glucan derivatives was ethylene glycol diglycidyl ether. A particular mole-to-mole ratio range of this crosslinker to the level of glucan dry solids (0.04:1 to 0.06:1) in the reactor during the manufacturing process was observed to be effective at providing the above-mentioned washing/builder benefit. Lower and higher amounts of crosslinking somewhat impacted performance, while other types of crosslinkers were shown to negatively impact performance. Lastly, addition of hydrophobic groups to the charged glucan polymers improved the shine benefit as well. Screening test methods for the evaluation of polymer effectiveness To evaluate polymer performance from a shine benefit, two separate screening methods were developed. One method was to evaluate the delay in haze formation in the liquid of the dishwasher. Haze formation typically is an indicator of the formation of inorganic scale. The so-called transmittance of a liquid indicates how well light passes unhindered through it. The more suspended insoluble particles are, the more light will be scattered, thereby resulting in less light transmittance. The other method was evaluating the actual deposition of inorganic scale on a standardized glass matrix. Anti-deposition screening test protocol The anti-deposition screening test protocol aimed to mimic the cycles of a dishwasher. In simple terms, a dishwasher passes through four phases and when simplified, passes through three phases. A main wash, a primary rinse and then a secondary rinse followed by drying. An anti-deposition assay was developed to mimic a dishwash cycle. Three stirring plates were setup, each with a different temperature, each reflecting the different stages of a wash cycle; a drying rack was also included. The wash cycle mimicry was chosen to be as follows: a main wash was 20 minutes at 50 to 55 °C, then a cold rinse step of 5 minutes at 25 °C, followed by a hot rinse step of 5 minutes at 50 to 55 °C, followed by drying at ambient temperature. In each of the three phases, intermediate stirring was done to mimic some mechanical movement; this stirring was at 150 rounds per minute for the wash cycle, and 180 rounds per minute for the two rinse steps. On the three stirring plates, there were 15 places for a stirring beaker. It was chosen for each run to use 10 beakers to avoid, e.g., time lapsing of pipetting steps. During these runs, 150-mL glass beakers were deployed and filled with 100 mL of hard water with a hardness of 21 °D. Per beaker, a glass microscope slide was added as a proxy for glassware. The glass slide was passed through the different phases after each given timeframe. The setup is shown as a picture in Example 1 of U.S. Patent Appl. Nos. 63/587,005 and 63/598,263, which are incorporated herein by reference. The system chosen for the anti-deposition assay was based on the following assumptions: The dishwash tablet is 18 grams, having the following features: - pH 10.2 to 10.5, - 30 weight percent of the tablet is carbonate (Na₂CO₃ anhydrous), - 30 weight percent of the tablet is citrate (sodium citrate-tribasic.2H₂O), - 5 weight percent of the tablet is the polymer of choice. The order of addition sequence is provided in Table 2. Table 2. Order of addition, steps & other information

*Refer to below text The washing volume taken was five liters for each step holding a replenishing volume of 90%, indicating that after the main wash, 4.5 liters would be pumped off, leaving behind 0.5 liters, adding 4.5 liters of new hard water to the dishwasher moving from the main wash to the cold rinse and from the cold rinse moving into the hot rinse. These chemical amounts have been calculated back to fit into 100 ml systems. Three types of stock solution were made: - 10.8 g citrate dihydrate in 100 mL hard water (100x citrate stock) [1] - 10.8 g sodium carbonate in 100 mL demineralized (“demi”) water (100x carbonate stock) [2] - Individual 100x stock solutions were made with 2.16 g of each polymer in 100 mL of hard water [3] In the anti-deposition setup, only 10% of volume was transferred from the main wash beakers to the first rinse beakers. Transmittance assay utilizing a pipetting robot and plate reader A second aspect of polymer performance is its effectiveness in delaying crystal (scale) formation. The transmittance relates to the amount of turbidity a specific liquid has. The more haze, the more suspended particles, the less the transmittance, and the higher the turbidity. Despite the end result, it is less relevant that during a wash, the liquid remains clear, as long as suspended solids can be washed away during the rinse phases of the dishwasher. Delay in crystal (scale) formation and the ability to cause crystal growth arrest has its reflection on an improved transmittance of the liquid. Also, smaller, or less crystals, wash off more easily. To evaluate the effectiveness of a polymer in the delay of haze formation in the liquid, a transmittance assay was developed herein. The assay utilizes 96-well plates. The main wash could be mimicked with this assay. The preparation setup is described below. In Table 3, the steps on the robot and plate reader are described. It was chosen to make the below stock solutions, based on a similar setup of assumptions as the anti- deposition assay. The dishwash tablet was 18 grams, with the following values: - 30 weight percent of the tablet is carbonate (Na₂CO₃ anhydrous) - 30 weight percent of the tablet is citrate (sodium citrate-tribasic .2H2O) - 5 weight percent of the tablet is the polymer of choice. Sodium citrate 20X stock solution: 2.16 grams in 100 mL hard water [4] Sodium carbonate 20X stock solution: 2.16 grams in 100 mL demi water [5] Polymer 40X stock: 0.864 grams polymer in 100 mL hard water [6*] Plate preparation (manually): In the first row (A) – pipet 270 microliter of hard water (except well 12). In row A well 12, pipet 300 microliter of demi water. The to-be-tested polymers were tested in duplicate. In Row A well 1&2, added 30 microliters of polymer stock 1 [6] In Row A well 3&4, added 30 microliters of polymer stock 2 [6] In Row A well 5&6, added 30 microliters of polymer stock 3 [6] In Row A well 7&8, added 30 microliters of polymer stock 4 [6] In Row A well 9&10, added 30 microliters of polymer stock 5 [6] In Row A well 11, added 30 microliters of Acusol™ 588 stock [6] Pipetted up-and-down to ensure mixing. In all the other wells, Row B to H, except column 12, added 150 microliters of hard water using a multichannel pipet. Placed 150 microliters of demi water in each other well of column 12. In Row A (besides well 12), each well now contained 4X the normal concentration of polymer found in the main wash of a dishwash run. The plate was then sealed and taken to a BIOMEK pipetting robot. Table 3. Steps on the pipetting robot and plate reader

Example of synthesizing (crosslinked) carboxymethyl alpha-1,3-glucan Alpha-glucan with about 100% alpha-1,3 linkages was added to a thermostated 3-L glass lab reactor followed by addition of a mixed solvent (isopropanol, water, and methanol) under a constant stream of nitrogen to form an alpha-1,3-glucan slurry. Then, caustic soda in form of solid prills, and optionally a crosslinker, was/were added and the glucan was alkalized at 20 °C for 60 minutes while stirring. In the next step, chloroacetic acid was added to the reactor and the reaction mixture was heated to 70 °C and allowed to react for 120 minutes. The reaction mixture was then cooled to 20 °C, followed by its neutralization to pH 7.0 by addition of acetic acid. Crude CMG product was separated by filtration and washed several times with a methanol/isopropanol/water mixture (50/30/20 vol%). The washed product was dried overnight in a cabinet oven at 55 °C followed by milling.

Polymer crosslinking and crosslinkers To determine the effectiveness of crosslinkers and their amounts applied per weight of polymer, several prototypes were prepared, with different crosslinkers and different amounts of crosslinker. Table 4 shows the different crosslinkers applied. Table 5 displays reaction regimes used for crosslinking a type of alpha-1,3-glucan ether. In particular, an increasing level of crosslinker (EGDE) was applied to various carboxymethyl alpha-1,3- glucan ethers (CMG). Table 4.

**UHDP refers to alpha-glucan with a DPw of about 1600 to 1800, and about 100% alpha- 1,3 linkages. Full dishwash trial (14 cycles) To fully evaluate the screening test assay, a full dish trial was performed to justify the screening test. Since the test setup had different parameters than used in the screening test, results were not 1:1 relatable, but were expected to show similar trends. Images were made after 14 washes. The dishwash trial was performed with a minimal detergent formulation in order to stress the crosslinked polymers above a level that is normally expected. Parameters of the run are shown in Table 6. Table 6*. Dishwash plan and formulation as carried out during 14 runs Machine type / water: MIELE GSL2 / 21°dH (Ca:Mg @ 3:1) – based on demi water, no bicarbonate added Program: 65 °C / 10’ / 65 °C Repetitive cycles: visual check after every wash, pictures taken after 14 washes Salt: none Rinse aid: none Soil: 1X build-up test ballast soil (50 g) (Tensio protocol) Detergent: 17.7 g of ADD2d detergent (split sample) Polymer dosage: 1.3 g/wash Assessment: Photos in black booth of articles. Articles washed: MEPAL tube, melamine blue dish plate, long drink glass. * No rinse-aid was added to this detergent formulation Results Anti-deposition effect of different crosslinked alpha-glucan derivatives Over sixty different crosslinked polymer prototypes were tested, both at the common polymer concentration and including dose responses (indicating overdosing the crosslinked polymer to see an effect). The following trends were observed. 1. The more charge added to the water, the better the performance of delivering a “shine” benefit. Charge could be added in two ways, either with more polymer added to the water or the degree of substitution (chemical addition of charged groups to the polymer backbone). 2. These results applied to crosslinked carboxymethyl alpha-1,2-branched alpha-1,6-glucan ethers and crosslinked carboxymethyl alpha-1,3-glucan ethers, particularly when crosslinking was performed with EGDE. Results shown below. 3. Moderate crosslinking of alpha-glucan ether derivative had a surprising positive influence on the shine benefit, where little crosslinking had no effect and high crosslinking diminished the shine benefit. Results shown below. 4. The result summarized in point 2 was reinforced by the testing of carboxymethylated cellulose with increasing molecular weights, showing an improved shine benefit with increasing molecular weight. 5. The positive influence of crosslinking herein was only observed when using the crosslinker ethylene glycol diglycidyl ether (EGDE). Other crosslinkers (1,4-butanediol diglycidyl ether, trimethylolpropane triglycidyl ether, diethylene glycol diglycidyl ether) had little to no effect, or even a negative effect, on the shine benefit crosslinked alpha-glucan ether derivative. Only EGDE showed significantly improved performance in a narrow crosslinker content range. 6. The combination of increased charge density (e.g., provided by carboxyalkyl ether groups such as carboxymethyl ether groups) on alpha-1,3-glucan polymer backbone in combination with moderate crosslinking – specifically with EGDE crosslinker, where the ratio of EGDE to the charged alpha-1,3-glucan derivative was about 0.04 to 0.06 mole EGDE to about 1 mole alpha-glucan derivative – achieved the positive effect noted in point 5. 7. The charged groups on an alpha-glucan derivative such as an alpha-1,3- glucan derivative can be carboxylate groups (e.g., as comprised in carboxyalkyl groups such as carboxymethyl groups), sulfonate groups, or oxidized groups. 8. Additional types of functionalization such as hydrophobic modification (e.g., hydrophobic etherification such as by benzylation) were shown to positively contribute to providing a shine benefit to alpha-glucan derivatives substituted with charged groups. 9. The more charge an alpha-glucan derivative had, the better it was in delaying haze formation (i.e., providing shine benefit). This was shown, for example, using derivative I, which is an alpha-1,2-branched alpha-1,6-glucan derivatized with carboxymethyl groups (DoS of 2.3 to 2.6). Results of increasing charge of alpha-1,3-glucan derivative A set of carboxymethylated alpha-1,3-glucan ether (CMG) derivatives were tested in the same anti-deposition study to test the effect of increasing anionic derivative charge. The results are shown in FIG.1. The results of three concentration runs of three polymers with an increasing charge density and crosslinking are shown in FIG.1. The CMG derivatives were as follows: - OPE 36B: DPw ~1600-1800, non-crosslinked, DoS 0.86 with carboxymethyl. - OPE 97: DPw ~1600-1800, crosslinked (0.05 mole EGDE to 1 mole CMG), DoS 0.56 with carboxymethyl. - OPE 149: DPw ~1600-1800, crosslinked (0.08 mole EGDE to 1 mole CMG), DoS 0.97 with carboxymethyl. Each series was performed with increasing (doubling) in polymer concentration (normal concentration ^ 2X normal ^ 4X normal). ACUSOL 420 was used as an industry incumbent positive control. Results of intermediate crosslinking on CMG To show the effect of moderate crosslinking, a series of CMG derivatives was made having an increasing level of EGDE crosslinking (produced in accordance with Table 5). The CMG that was subjected to crosslinking had a DoS of about 0.54 to 0.56 with carboxymethyl. The relative amount of EGDE to CMG (mol/mol) used here is listed below each slide in FIG.2. The method used was the anti-deposition test. What can be observed in FIG.2 is that there is an optimum in functionality with a crosslinker level of 0.04 to 0.05 mole crosslinker per one mole CMG. Results using carboxymethyl cellulose In addition, a series of carboxymethylated cellulose (CMC) derivatives was tested to show the effect of increasing polymer molecular weight on inhibition of scale formation. Results are shown in FIG.3. Here CMC with DoS 0.7 or 0.9 was applied in the same way as the CMG. However, the CMC samples were of increasing molecular weight, and not crosslinked. What is observed is an increased performance with increased molecular size. Results of adding more anionic charge to alpha-1,3-glucan To show the effect of anionic charge addition on alpha-1,3-glucan, a set of CMG derivatives (each based on DPw ~1600-1800, ~100% alpha-1,3-linked glucan polymer), was selected for anti-deposition testing. Table 7 represents the selected CMG compounds, none of which were crosslinked. Results of the anti-deposition run are shown in FIG.4. What can be observed is that, as more anionic charge is added to the polymer, the better the anti-deposition behavior (i.e., the more transparent the slide is). This result correlates to the above data (FIG.1) in which increasing amounts of polymer was added to the study vessels, leading to increased shine benefit performance. OPE 97, which was a moderately crosslinked CMG (above), was included as a reference and again showed the advantage of moderate crosslinking FIG.4). Table 7.

0.52 0.86 Results of using other crosslinkers for crosslinking CMG As shown above, the majority of the EGDE-crosslinked CMG compounds showed improved results over non-crosslinked CMG samples when the crosslinking level was chosen correctly. To evaluate the effect of alternate crosslinkers aside from EGDE, the anti-deposition test was performed with CMG samples crosslinked with other crosslinkers (listed in Table 8). CMG compounds for crosslinking were chosen based on having a similar level of charge density as one of the CMG compounds (OPE 97) that was used for EGDE-crosslinking and that showed improved performance (Table 8). OPE 97 was chosen as a reference for this study. Results of the anti-deposition test are shown in FIG.5. What is shown is that using other crosslinkers did not lead to the same improvement in shine benefit as when CMG was crosslinked with EGDE. When crosslinked with 1,4-butanediol diglycidyl ether, large dendritic flocs appeared that precipitated as large crystals on the glass slide. All the crosslinked (non-EGDE) samples unexpectedly gave a performance similar to the no-polymer control. However, the EGDE-crosslinked sample exhibited anti- deposition activity, consistent with the above results. Table 8.

Other derivatized alpha-glucan backbones were tested, such as derivatized alpha-1,2- branched alpha-1,6-glucan (alpha-1,2-1,6-glucan). Data on these various polymers are provided in Table 9. Shine benefit results using these polymers in anti-deposition testing are provided in FIGs.6, 7 and 8. What can be observed is that carboxymethylated alpha- 1,2-1,6-glucan (with or without inclusion of oxidation-derived carboxylate groups, which are in addition to the carboxylate groups of the carboxymethyl groups), which are highly anionically charged, provide a significant improvement in anti-deposition over the no- polymer control (FIG.6). The same result similarly applies to using carboxymethyl benzyl alpha-1,3-glucan ether derivative (FIG.7). Table 9.

Results of transmittance testing (see above: Transmittance assay utilizing a pipetting robot and plate reader) To determine how well a (crosslinked) glucan polymer of the Examples was able to reduce haze formation, a transmittance test assay was developed. Some of the results from this work are provided in FIGs.9-13. An optical density at 600 nanometers (OD600) was applied. These analyses gave a good indication of the level of suspended particles in a liquid. Testing was done as well on 21 °D (hardness) and at 55 °C. Similar amounts of polymer were used as in the anti-deposition test. Results of automatic dishwashing test (14-cycle) A complete automatic dishwasher trial was performed in which polymers herein were used in a detergent formulation. Shine benefit of polymers was evaluated accordingly. The detergent formulation and method in which the full dish trial was performed are described above (including Table 6). Examples of results after 14 washes are provided in FIGs.14- 16. Three dishware substrates were chosen for this study: MEPAL tubes, melamine plates, and LIBBEY long drink glasses. It should be noted that the full dishwash test partially echoes the anti-deposition test and that improved performance is expected with the biopolymers when a rinse aid is added to the formulation used. Example 2 Summary of Example 2 Crosslinked carboxymethyl alpha-1,3-glucan (CMG) showed suitable properties as rheology modifiers in personal care applications. The crosslinked CMG compounds were characterized in terms of their viscosity and rheological properties in aqueous suspensions, showing viscosity and yield stress ranges comparable with synthetic carbomers and significantly higher than natural gums. When formulated in model personal care oil-in-water (O/W) emulsions, the positive rheological properties of crosslinked CMGs translated into improved emulsion stability, yield stress and more homogeneous emulsion droplet dispersions, allowing the use of significantly lower levels of polymer in the personal care formulations, when compared to widely used synthetic carbomers. Representative process for preparing crosslinked CMG Slurry powder of alpha-1,3-glucan (DPw ~1600-1800) with a particle size <100 µm was adjusted for a water content of 8% w/v and added to a reactor at a loading of 7% w/v in IPA/water. Under continuous overhead mixing, the glucan slurry was activated by adding a suitable amount of 50% NaOH in molar ratios ranging 0.5 to 3.0. This preparation was held at room temperature for 45 minutes and then the desired amount of crosslinker was added at molar ratios ranging from 0.01 to 0.2. Suitable crosslinkers included those listed in Table 4, among others. This crosslinking preparation was stirred at room temperature for 15 minutes and then, using a feeding pump, the desired amount of chloroacetic acid (CAA) dissolved in IPA was added over a 40-minute period in CAA:glucan molar ratios ranging from 0.5 to 2.0 (to commence carboxymethylation). Heating was applied while feeding the CAA. After all the CAA was fed and the reactor temperature had reached 70 °C, the temperature was held for 2 hours. The reactor was then cooled down to 50 °C and the reaction was neutralized to pH 7 using acetic acid (glacial), thereby obtaining a white to off- white polymer slurry. The polymer slurry was purified by successive vacuum filtration and washing with mixtures of IPA, methanol and water, followed by a final washing and filtration with methanol. Finally, the purified slurry was dried under vacuum overnight at 60 °C to yield a white to off-white crosslinked CMG powder. In the below testing, the crosslinked CMG samples were prepared using ethylene glycol diglycidyl ether (EGDE) as a crosslinking agent. EGDE was added for crosslinking at a molar ratio of 0.01 to 0.1 mol relative to the mol of CMG, and the selected candidates for testing had an EDGE-to-CMG mol ratio content of about 0.08. Preparation of dispersions of crosslinked CMG Crosslinked CMG powder was dispersed in deionized water at concentrations ranging from 0.25 to 2.00% w/v under continuous stirring at 500 rpm using a DLS Digital Overhead Stirrer (Thermo Fisher Scientific, Waltham, MA) until homogeneity was reached; if necessary, heat could be applied up to 60 °C. After homogeneity was reached, the pH of the preparations was adjusted to 6.5 using either sodium hydroxide (5 N) or hydrochloric acid (5 N). The crosslinked CMG dispersions showed different ranges of viscosity from semi-fluid to thick gels, as a function of the final concentration. Xanthan gum (Clariant, Louisville, KY) and carbomer (ULTREZ 30, Lubrizol, Wickliffe, OH) were used as reference polymers for comparative analysis of viscosity, emulsion stability and yield stress. Control dispersions were prepared following the protocol described for the crosslinked CMG samples. The samples were stored at 23 °C for at least 3 days before carrying out viscosity and rheological characterization. Effect of crosslinked CMG on relative viscosity and rheological behavior in aqueous dispersions The relative viscosity of each polymer dispersion was determined at various shear rates ranging from 10 to 250 rpm, using a Brookfield DV2T Viscometer (Middleboro, MA) equipped with a recirculating bath to control temperature (20 °C) and an RV-6 spindle. The RV values for each sample were recorded and averaged for a period of 60 seconds for each determined shear rate value. Results, shown in FIG.17, demonstrate that crosslinked CMG (0.46 DoS) showed an increase in dispersion viscosity as a function of the increase in polymer concentration, with values of relative viscosity significantly higher than natural gum (xanthan) and slightly lower than synthetic carbomer (ULTREZ 30), but reaching similar values of relative viscosity at higher polymer concentrations (2% w/v). The effect of crosslinked CMG on preserving dispersion stability despite addition of sodium chloride was determined in comparison to synthetic carbomer control (ULTREZ 30). Polymer dispersions at a concentration 1% w/v were prepared as described above and mixed with different amounts of sodium chloride to final salt concentrations of 0.1% to 4% w/v. The relative viscosity of the dispersions upon changing the salt concentration was determined using a Brookfield DV2T Viscometer as described above. Results, shown in FIG.18, demonstrate that crosslinked CMG (0.46 DoS) showed a significant advantage over synthetic carbomer (ULTREZ 30) in terms of maintaining viscosity stability despite an increase in salt content, which is an important property when formulating personal care products as well as other products. Synthetic carbomer dispersions showed a significant drop in relative viscosity when small amounts of salt were added to the system (0.1%), whereas, at the same polymer concentration, the crosslinked CMG was able to maintain significantly higher viscosity values; this was observed even up to 4% w/v sodium chloride addition (FIG.18). The rheological behavior of the polymer dispersions was evaluated under continuous and oscillatory flow programs using a Rheometer Discovery HR-20 (TA Instruments, New Castle, DE), equipped with an ARES G240-mm geometry with a fixed gap (0.098 mm). All the measurements were conducted at a controlled temperature of 23 °C. FIGs.19A-D show the changes on viscosity curves as a function of shear rate for increasing concentrations (0.25% to 2% w/v) of crosslinked CMG polymer (DoS 0.4-0.5, FIGs.19C-D) and compared to the ones for synthetic carbomer (ULTREZ 10 or 30, FIGs.19A-B). Results suggest the vertical gaps that separate the viscosity curves for each polymer concentration tended to narrow down for carbomer as a function of the increase in its concentration, aligning with the results obtained for Brookfield viscosity in FIG.17, that indicated viscosity values reached a plateau at concentrations higher than 1% w/v, whereas the gap for crosslinked CMG tended to become wider at the highest concentrations, suggesting a more effective linear increase in viscosity. Yield strength is important because it characterizes the highest stress a material can tolerate before permanent deformation occurs. In the chemical and cosmetic industries, viscosity testing and determination of yield stress are very important parameters for quality control and performance assessments, allowing manufacturers to predict how products will behave once they are in the hands of the consumer. FIG.20 shows rheological behavior (shear stress vs. shear rate), and FIG.21 shows storage modulus and yield stress, in aqueous dispersions of crosslinked CMG (DoS 0.4-0.5) as compared to carbomer (ULTREZ 30, highlighted with a star in each figure) at slightly higher concentrations (1.5x-2x) of crosslinked CMG, without the need for pH adjustment. Variation in yield stress for crosslinked CMG in aqueous dispersions as a function of DoS is shown in FIG.22, suggesting a direct linear increase in yield stress as function of the increase in DoS, until a maximum value around DoS 0.5 is reached and then the yield stress appeared to drop. Effect of crosslinked CMG on rheological behavior and emulsion stability of formulated model personal care products Rheology modifiers are added to formulations to increase viscosity, promote yield stress, and to control the finished product’s properties and characteristics in a desired manner. Model personal care oil-in-water (O/W) emulsions were formulated containing crosslinked CMG, following the formula composition detailed in Table 10, to assess the effect of crosslinked CMG on rheological behavior and emulsion stability.

_{if required} Cetearyl Alcohol The preliminary physicochemical stability of the formulated O/W emulsions containing crosslinked CMG was evaluated according to freezing (-5 ± 2 °C) and thawing (40 ± 2 °C) cycles of 24 hours, for 12 days, covering a total of three cycles. The formulations were tested for sedimentation by centrifugation, at the beginning of and at the end of each study, using LUMiSizer equipment (LUM GmbH, Berlin, Germany). Samples were placed in the cuvette of 2 mm optical path and centrifuged at 4000 rpm (5976 g) for 60 minutes. While the samples were being exposed to the centrifugal force, a near-infrared light lamp illuminated the cuvette, allowing the measurement of the transmitted light intensity. This measurement was obtained as a function of time and position of the sample over the entire length of the cuvette, thereby providing transmittance profiles. The instability index (I) was determined by the transmittance profiles using software SepView 6.0 (LUM GmbH, Berlin, Germany). Results for emulsion stability are summarized in Table 11, suggesting that crosslinked CMG polymers of a wide range of DoS (0.2-0.5) had improved stabilizing activity on O/W emulsions at 0.5% polymer content, after successive cycles of freeze- thawing, when compared to carbomers (ULTREZ 10 and ULTREZ 30) and natural gum (xanthan). Table 11. Variation on instability index at 23 °C for O/W emulsions containing 0.5% w/v crosslinked CMG (DoS 0.2 to 0.5) as a function of successive cycles of freeze-thawing in comparison to synthetic carbomers (ULTREZ 10 and 30) and natural gum (xanthan) Sample ID Cycle 0 Cycle 1 Cycle 2 Cycle 3 Crosslinked CMG (DoS 0.21) 0.01 0.01 0.01 0.01 Crosslinked CMG (DoS 0.25) 0.01 0.01 0.01 0.01 Crosslinked CMG (DoS 0.32) 0.01 0.01 0.01 0.01 Crosslinked CMG (DoS 0.46) 0.01 0.01 0.01 0.01 Crosslinked CMG (DoS 0.50) 0.01 0.01 0.01 0.01 Natural Gum (xanthan) 0.01 0.04 0.05 0.09 Carbomer (ULTREZ 10) 0.12 0.38 0.75 0.96 Carbomer (ULTREZ 30) 0.04 0.08 0.12 0.32 Changes in droplet size of O/W emulsions containing crosslinked CMG at 0.5% w/v were evaluated by optical microscopy (Olympus BX41, Tokyo, Japan) and compared with carbomer (ULTREZ 30). The O/W emulsions were diluted ten-fold in deionized water and applied to a glass slide prior to visualization under a microscope; results are shown in FIG. 23. Microscopy imaging (20X) suggested that crosslinked CMG (DoS 0.4-0.5) showed more homogeneous droplet distribution than carbomers and the results agree with the instability index obtained by LUMiSizer analysis, indicating smaller and more homogeneous droplet sizes observed in CMG samples may be driving its lower instability indices and improved emulsion stabilization, as compared to carbomers. FIGs.24A-B show the rheological analysis of model O/W emulsions containing crosslinked CMG (DoS 0.4-0.5) according to the above-described protocols. These results suggest significantly improved yield stress and rheological behavior, when compared to the carbomer (ULTREZ 30) formulation at the same polymer content (0.5% w/v) (FIG.24A). The range difference between the rheology curves for crosslinked CMG against carbomer allowed for reducing its polymer content by half to 0.25% w/v (FIG.24B), while keeping enhanced rheological properties when compared to carbomer at higher concentration (0.5% w/v, highlighted with star).
