Description

FOAMING CLEANING COMPOSITION DOMAIN

The present invention relates to a cleaning composition of natural origin.

CONTEXT

Removing stubborn makeup has always been a challenge and pain point for consumers, particularly for waterproof mascara, long-wearing foundation, and long-lasting lip products. Typical “makeup removers” and cleansers offer reasonably acceptable pigment removal capabilities, but can struggle with removing heavy makeup. A major drawback of existing makeup remover formulations is the inclusion of high amounts of oils that can feel greasy and leave skin feeling less fresh and clean than most consumers desire. And current cleansers and makeup removers can include alcohols, which can dry out the skin, and sulfate-based surfactants, silicones, and other synthetic components that can be irritating. These ingredients are less appealing to consumers looking for more natural products. Additionally, these makeup remover products do not include foaming, a feature that most consumers find desirable. And often many of today's natural cleansers don't have a pleasant aesthetic or foaming, don't apply with a thick feel, don't effectively remove heavy makeup, and don't come off cleanly after rinsing.

As a result, there is a need for a more natural cleansing composition that will allow easy and effective makeup removal in a thick form with a strong foam on application and that will leave the skin feeling clean and fresh after use without the use of silicone, alcohols, aggressive surfactants and sulfates.

DETAILED DESCRIPTION

“All-natural” as used herein means that all intentionally added ingredient carbon atoms are derived from natural sources in accordance with ISO 16128.

“Cleanser” or “foaming cleansing composition” as used herein means and refers to any foaming cleansing composition used for application to keratinous tissue for one or more of skin cleansing, makeup removal and the like.

“Cosmetically acceptable” as used herein means and refers to a carrier that is compatible with any keratinous substrate.

“Cosmetically acceptable” means a carrier that is compatible with any keratinous substrate.

As used herein with respect to the foaming property of cleansing formulations, including the inventive cleansing composition, the term "foaming" means and refers to the ability of a composition (inventive or comparative) to develop a foam upon rubbing that would be associated with the application and gentle scrubbing of skin or other keratinous substrates with the formulation. Reference is made to a known testing method of establishing in vitro foam formation using equipment well known in the art, namely using a Krauss DFA100 TM Dynamic Foam Analyzer which provides a relative measure of the foam formation achieved. In some examples herein, foaming is described as the relative formation of foam density per unit area relative to other formulations tested under the same conditions. In some examples, counting bubbles using the disclosed foam analyzer is provided. Foaming capacity, or foaming or high foaming as used herein relative to foaming on a keratinous substrate, such as facial skin, is based on a scale of low to high and represented on a scale of 1 to 10.

“Free” and “free from” and “exclude” or “excluded” each indicate that no reliably measurable excluded material, e.g., an excluded volatile silicone oil or an excluded surfactant or other excluded material as described herein, is present in the foaming cleansing composition. The term “substantially free” means that, while it is preferred that no excluded material be present in the composition, it is possible to have very small amounts of the excluded material in the composition of the invention, provided that such amounts do not materially affect the beneficial properties of the foaming cleansing composition. In particular, “substantially free” means that the excluded material may be present in the foaming cleansing composition in an amount of less than 5%, or less than 4%, or less than 3%, or less than 2%, or less than 1%, or less than 0.1% by weight, based on the total weight of the foaming cleansing composition.

“Keratinous substance” and “keratinous tissue” each include, but are not limited to, skin, hair and nails.

“Natural” or “naturally derived” as used herein means and refers to cosmetically acceptable materials and components that are one or more of those directly obtained from nature, are obtained from nature with minimal processing, and are derivatives of materials that are obtained from nature. The foaming cleansing composition according to the present disclosure is in some embodiments up to 99.11% natural, or “highly natural.”

“Petrochemical-free” means that the excluded petrochemicals have not been added as a component. Some specific, but not limiting, examples of petrochemicals that are absent from the cosmetic foaming cleansing composition include benzalkonium chloride, isododecane, isohexadecane, and the like. In some embodiments, the foaming cleansing composition is not petrochemical-free, but is formulated to have an amount of petrochemicals that is equal to or less than the amounts found in similar commercially available compositions.

“Silicone-free” means that the excluded silicones have not been added as a component. In some embodiments, a composition is free of silicones. Some specific, but not limited, examples of silicones that are absent from the cosmetic foaming cleansing composition include, but are not limited to, silicone polymers, for example selected from dimethicone, cyclopentasiloxane and other silicone oils, and silicone elastomers.

“Skin” as used herein means and refers to keratin-containing skin materials such as facial and body skin, scalp, eyebrows and lips.

“Stable” and “Stability” as used herein mean that the foaming cleansing composition exhibits no evidence of significant change in one or more of color, odor, pH, or viscosity at room temperature over a period of at least two months, as evidenced by either or both unassisted visual or microscopic inspection, wherein the foaming cleansing composition is free or substantially free of crystal formation, precipitates, or phase separation of oily components and water. In some embodiments, the inventive composition, including as exemplified herein, is developed as a thick, creamy formulation for packaging and use in a tube container, such that a measure of stability is the retention of the composition in the tube without flow for at least one month, or two months or more, at room temperatures and at temperatures in the range of about 25°C to about 45°C. In various embodiments, an inventive composition remains stable at temperatures in the range of about 25°C to about 45°C, for a period of at least one month, or at least two months, or more, or any value, range, or subrange therebetween. In some embodiments, a cleaning composition is stable at 25°C for at least one month, or at least two months, or more, or any value, range, or subrange therebetween. In some embodiments, a cleaning composition is stable at 45°C for at least one month, or at least two months, or more, or any value, range, or subrange therebetween.

“Surfactant-free” means that the excluded surfactants have not been added as a component. In some particular embodiments, the foaming cleansing composition is free of surfactants. In some embodiments, the foaming cleansing composition is free of ethylene glycol (PEG) surfactants or sulfate/sulfonate surfactants, or combinations thereof. Those skilled in the art will appreciate that a surfactant may be present in a composition via its presence in one or more of the formulation components; thus, in some embodiments, the foaming cleansing composition may be “substantially surfactant-free” wherein a surfactant is present at a concentration that does not exceed 5% by weight, and in some instances is present at no more than 3% by weight, and in some instances is present at no more than 1% by weight, based on the weight of the cosmetic foaming cleansing composition. In some particular embodiments, “surfactant-free” means that the cosmetic foaming cleansing composition is free of or specifically devoid of surfactant. Some specific but non-limiting examples of surfactants that are absent from the cleansing composition include those with a C10-C20 fatty alcohol or acid hydrophobe condensed with from about 2 to about 100 moles of ethylene oxide or propylene oxide per mole of hydrophobe; C2-C10 alkyl phenols condensed with from 2 to 20 moles of alkylene oxide; mono- and di-fatty acid esters of ethylene glycol; fatty acid monoglyceride; sorbitan; mono- and di-fatty acids of C8-C20; polyoxyethylene sorbitan; alkyl polyglycosides and fatty amides of saccharides (e.g., methyl gluconamides); alkyl ether sulfates and sulfonates; alkyl sulfates and sulfonates; alkylbenzene sulfonates; alkyl and dialkyl sulfosuccinates; C8-C20 acyl isethionates; C8-C20 alkyl ether phosphates; alkyl ether carboxylate. Some specific surfactants that are absent from the cleaning composition include PEG-100 stearate; PEG-20 stearate and other poly(ethylene glycol) esters; sucrose stearate and other sugar ester emulsifiers; glyceryl stearate and other glycerol esters; disodium ethylene dicocamide PEG-15 disulfate; sodium steroyl glutamate and other fatty amides; steareth-100 and other fatty ethers; acrylates/C10-30 alkyl acrylate cross-linked copolymer and similar polymeric emulsifiers.

The disclosure provides, in various embodiments, a foaming cleansing composition that includes a rhamnolipid, at least one cationic polymer, and at least one naturally occurring viscosity-modifying polymeric thickener for a water-based system. In some embodiments, the makeup remover composition may include at least one anionic surfactant. In the various embodiments, water is present from about 60% to about 90% by weight of the makeup remover composition. In some embodiments, the makeup remover composition may include as a naturally occurring viscosity-modifying polymeric thickener for a water-based system one or more of xanthan gum (and) sclerotium gum (and) lecithin (and) pullulan, xanthan gum, carbomer 980, hydroxypropyl starch phosphate, ammonium polyacryloyldimethyltaurate, hydroxyethylcellulose, acrylate copolymer, sclerotium gum, or combinations thereof. In some embodiments, the at least one anionic surfactant is selected from disodium cocoyl glutamate (and) sodium cocoyl glutamate, or combinations thereof. And in some embodiments, the foaming cleansing composition may include antimicrobial agents, pH adjusters, chelating agents, humectants, and other additives and active ingredients. In some embodiments, the foaming cleansing composition may include caprylyl glycol, sodium hydroxide, sorbitol, tetrasodium glutamate diacetate, glycerin, or combinations thereof.

In some embodiments, the inventive composition is 100% biodegradable and more than 99% renewable, and provides unexpected benefits that include overall ease of makeup removal, particularly after rinsing, compared to reference/comparative compositions, and pleasant lathering. In some embodiments, the inventive composition demonstrates better performance than commercial references while including a higher amount of naturally derived ingredients and in the absence of surfactants, alcohols and other ingredients that are perceived as harsh, including pleasant lathering properties and makeup removal capacity, as exemplified in in vitro and in vivo testing.

In some embodiments, the cleaning composition is free or essentially free of harsh chemicals and non-naturally derived ingredients (silicones, alcohol, parabens, fragrance, sulfates).

According to the disclosure, the inventive composition of natural origin including the disclosed biosurfactant, the cationic polymer and the viscosity-modifying polymeric thickener, offers unexpected benefits that include high density and larger bubble size compared to commercial foaming cleansers as exemplified herein, boosts the ability to remove long-lasting makeup with a fine and pleasant texture and good spreading property. Typical water-based compositions with a single biosurfactant show very poor foaming performance. The inventive cosmetic composition which includes a rhamnolipid biosurfactant (Glycolipid) together with a cationic polymer, as exemplified herein including chitosan, and at least one natural viscosity modifying polymer, as exemplified herein including algin/alginate and Siligel (TM), demonstrates better performance than commercial references, such as makeup removal ability, and pleasant foaming properties as exemplified in in vitro and in vivo testing. Thus, the foaming cleansing composition provides superior surface activity and biodegradability, lower toxicity and environmental compatibility with pleasant aesthetics, including pleasant foaming and effective makeup removal.

In some embodiments, the foaming cleansing composition is free or essentially free of harsh chemicals and non-naturally derived ingredients (silicones, alcohol, parabens, fragrance, sulfates).

Through expert evaluations of makeup removal efficacy, the foaming cleansing composition according to the disclosure demonstrated performance at the same level as or better than competing compositions in removing foundation and excels in removing eye and lip makeup.

In some embodiments, the foaming cleansing composition is a skin cleanser, shampoo or body wash and in some particular embodiments, the composition is a facial cleanser and/or makeup remover.

As specified above, rhamnolipids are usually prepared by processes known to those skilled in the art from bacterial producers, such as Pseudomonas .

Suitable fermentation processes are reviewed by D. Haferburg, R. Hommel, R. Claus and H.P. Kleber in Adv. Biochem. Ing./Biotechnol. (1986), 33, 53-90, and by F. Wagner, H. Bock and A. Kretschmar in Fermentation (ed. R.M. Lafferty) (1981), 181-192, Springer Verlag, Vienna.

As a rhamnolipid, one can use the one sold under the name Rheance One by Evonik (INCI name: glycolipids).

In some embodiments, the rhamnolipid is present in the foaming cleansing composition at about 5% by weight of the foaming cleansing composition.

The at least one rhamnolipid glycolipid is present in the foaming cleansing composition according to the disclosure from about 0.1% to about 20% by weight, or from about 1% to about 10% by weight, or from about 2% to about 8%, or from about 3% to about 5%, or about 5%, or any suitable combination, subcombination, range or subrange of these values by weight, based on the weight of the foaming cleansing composition.

Thus, a rhamnolipid glycolipid or combination of rhamnolipid glycolipids may be present, by weight, relative to the total weight of the foaming cleansing composition, from about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 to about 20 weight percent, including increments and ranges therein.

Cationic polymer

In various embodiments, the foaming cleansing composition comprises at least one cationic polymer. In some embodiments, the at least one cationic polymer is naturally occurring.

Examples of cationic polymers include polysaccharide-based delivery molecules (e.g., chitosan, cyclodextrin, cationic gelatin, cationic dextran, cationic cellulose), cationic peptides and their derivatives (e.g., polylysine, polyornithine), peptide/protein polymers (e.g., histone, collagen), linear or branched synthetic polymers (e.g., polybrene, polyethyleneimine), natural polymers (e.g., histone, collagen), synthetic dendrimers, thiolated cationic biopolymers (naturally occurring thiomers or naturally occurring dendrimers, e.g., chitosan-cysteine, chitosan-thiobutbutylamidine, and chitosan-thioglycolic acid).

Examples of naturally occurring cationic polymers include polysaccharide-based delivery molecules (e.g., chitosan, cyclodextrin, cationic gelatin, cationic dextran, cationic cellulose); cationic peptides and their derivatives (e.g., polylysine, polyornithine), peptide/protein polymers (e.g., histone, collagen); thiolated cationic biopolymers (naturally occurring thiomers or naturally occurring dendrimers, e.g., chitosan-cysteine, chitosan-thiobutylamidine, chitosan-thioglycolic acid); or combinations thereof.

In some embodiments, the foaming cleansing composition comprises the at least one naturally occurring cationic chitosan selected from chitosan oligosaccharide, chitosan (or polymeric chitosan having a molecular weight (MW) in a range of about 1 kDa to about 1000 kDa), chitosan derivatives, including derivatives having enhanced solubility, or combinations thereof.

In various embodiments, the chitosan has a MW in a range of about 1 kDa to about 1000 kDa. In some particular embodiments, the chitosan has a molecular weight that is “low” and is in the range of about 1 kDa to about 20 kDa, or about 10 kDa to about 20 kDa, or about 12 kDa to about 18 kDa.

In some embodiments, the at least one naturally occurring cationic polymer is present from about 0.05% to about 2%, or from about 0.2% to about 0.4%, based on the weight of the foaming cleansing composition and comprises chitosan.

Chitosan is a unique polycation because its charge density depends on the degree of acetylation and the pH of the medium, and its solubility depends on the degree of acetylation and the molecular weight. And while chitosan oligomers are soluble over a wide pH range, from acidic to basic (i.e., physiological pH 7.4), chitosan with increasing molecular weight is only soluble in acidic aqueous media, even at high degrees of deacetylation. This lack of solubility at neutral and basic pH has hampered the use of chitosan in some applications under neutral physiological conditions (i.e., pH 7.4).

The foaming cleansing composition according to the disclosure has a pH in some embodiments that is equal to or less than about 6.5. In some embodiments, the foaming cleansing composition has a pH in the range of about 4.5 to about 6.5, and more particularly about 6 to 6.5, or about 6.2 to about 6.4.

The at least one naturally occurring cationic polymer is present in the foaming cleansing composition according to the disclosure at about 0.05% to about 2%, or about 0.05% to about 1%, or about 0.1% to about 0.8%, or about 0.1% to about 0.5%, or about 0.2% to about 0.4%, or about 0.4%, or about 0.4%, or any suitable combination, subcombination, range or subrange of these values by weight, based on the weight of the foaming cleansing composition.

Additionally, in some cases, the total amount of non-sulfate anionic surfactants in the surfactant system is greater than the total amount of all other surfactant types in the surfactant system, including amphoteric surfactants, nonionic surfactants, and any sulfate-based anionic surfactants that may be present. In other words, the term "all other surfactants" refers to all surfactants in the foaming cleansing composition other than anionic surfactants.

Although the disclosure has been described with reference to one embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the disclosure. Furthermore, numerous modifications may be made to adapt a particular situation or a particular material to the teachings of the disclosure without departing from the essential scope thereof. Accordingly, it is intended that the disclosure not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this disclosure, but that the disclosure include all embodiments falling within the scope of the appended claims.

The articles "a" and "an", as used herein, mean one or more when applied to any feature in embodiments of the present disclosure described in the specification and claims. The use of "a" and "an" does not limit the meaning to a single feature, unless such a limitation is expressly indicated. The article "the", "the", "the" preceding singular or plural nouns or noun phrases denotes a specified particular feature or features and may have a singular or plural connotation depending on the context in which it is used. The adjective "any/all/any" means one, some or all indistinctly, regardless of the quantity.

“At least one” as used herein means one or more and thus includes individual components as well as mixtures/combinations.

The transitional terms “comprising”, “consisting essentially of” and “consisting of”, when used in the appended claims, in their original and amended form, define the scope of the claim with respect to the additional elements or steps not mentioned, if any, which are excluded from the scope of the claim(s). The term “comprising” is intended to be inclusive or broad and does not exclude any additional elements, processes, steps or materials not mentioned. The term “consisting of” excludes any elements, steps or materials other than those specified in the claim and, in the latter case, impurities ordinarily associated with the specified material(s). The term “consisting essentially of” limits the scope of a claim to the elements, steps or materials specified and to those which do not materially affect the fundamental and novel feature(s) of the claimed disclosure. All materials and methods described herein that embody the present disclosure may, in other embodiments, be more specifically defined by any of the transitional terms “comprising,” “consisting essentially of,” and “consisting of.”

In some embodiments, the terms “Exclude,” “Exempt,” and “Substantially Free” mean that no reliably measurable excluded material, typically 0% by weight, based on the total weight of the foaming cleansing composition, or, for example, no amount greater than about 5%, by weight, based on the total weight of the foaming cleansing composition, of any excluded material as described herein is present in the foaming cleansing composition. The terms “Exclude,” “Exempt,” and “Substantially Free” mean that, while it is preferable that no excluded material be present in the foaming cleansing composition, it is possible to have very small amounts of the excluded material in the composition of the invention, provided that such amounts do not materially affect the beneficial properties of the foaming cleansing composition. In particular, the terms “Exclude,” “Exempt,” and “Substantially Exempt” mean that the material may be present in the foaming cleaning composition in an amount of less than 5%, or less than 4%, or less than 3%, or less than 2%, or less than 1%, or less than 0.1% by weight, based on the total weight of the foaming cleaning composition. In accordance with the various embodiments, it is contemplated that some or all of the following ingredients may be excluded from the foaming cleaning composition of the invention: alcohols, for example, but not limited to, monohydric alcohols; powders including nylon-12, polymethyl methacrylate, polyethylene beads, and powders considered to be microplastics; lactic acid, glycolic acid, tartaric acid, mandelic acid, citric acid, salicylic acid and their derivatives (including 5-n-octanoylsalicylic acid, salicylate, sodium salicylate and willow extract), capryloyl salicylic acid, beta-hydroxybutanoic acid, propionic acid, beta-hydroxymethylbutyric acid, carnitine tropic acid and trethocanic acid; alkyl polyglucosides selected from the group consisting of decyl glucoside, lauryl glucoside, octyl glucoside, coco glucoside, caprylyl/capryl glucoside, sodium lauryl glucose carboxylate, and combinations thereof; surfactants with a C10-C20 fatty alcohol or an acid hydrophobe condensed with from about 2 to about 100 moles of ethylene oxide or propylene oxide per mole of hydrophobe; C2-C10 alkylphenols condensed with 2 to 20 moles of alkylene oxide; mono- and di-fatty acid esters of ethylene glycol; fatty acid monoglyceride; sorbitan; mono- and di-fatty acids C8-C20; polyoxyethylene sorbitan; alkyl polyglycosides and fatty amides of saccharide (e.g. methyl gluconamides); alkyl ether sulfate and sulfonates; alkyl sulfate and sulfonates; alkylbenzene sulfate and sulfonates; alkyl and dialkyl sulfosuccinates; C8-C20 acyl isethionates; C8-C20 alkyl ether phosphates; alkyl ether carboxylate, alkyl ether, PEG-100 stearate; PEG-20 stearate and other poly(ethylene glycol) esters; Polyethylene glycol (PEG) surfactants, polypropylene glycol (PPG) surfactants, sulfate surfactants, for example, taurate surfactants; sucrose stearate and other sugar ester emulsifiers; glyceryl stearate and other glycerol esters; PEG-15 disodium ethylene dicocamide disulfate; sodium steroylglutamate and other fatty amides; steareth-100 and other fatty ethers, cationic surfactants and other cationic compounds; silicones, such as silicone polymers, silicone elastomers and silicone oils, for example selected from dimethicone, cyclopentasiloxane, cyclohexasiloxane and combinations thereof; phthalates, parabens, sulfates, polyquaternium, microplastics, synthetic colorants, gelling agents and combinations thereof.

All percentages and ratios are calculated by weight unless otherwise specified. All percentages are calculated based on the total composition unless otherwise specified. Generally, unless otherwise expressly specified herein, “weight” or “amount” as used herein with respect to the percentage amount of an ingredient refers to the amount of raw material comprising the ingredient, the raw material may be described herein as comprising less than and up to 100% of the ingredient’s activity. Accordingly, the weight percentage of an active ingredient in a composition is represented as the amount of raw material containing the active ingredient that is used and may or may not reflect the final percentage of the active ingredient, the final percentage of the active ingredient depending on the weight percentage of the active ingredient in the raw material.

All ranges and quantities given herein are intended to include subranges and quantities using any point disclosed as a boundary. Thus, a range of “1% to 10%,” such as 2% to 8%, such as 3% to 5%,” is intended to encompass ranges of “1% to 8%,” “1% to 5%,” “2% to 10%,” and so on. All numbers, quantities, ranges, etc. are intended to be modified by the term “about,” whether or not expressly stated. Similarly, a range given of “about 1% to 10%” is intended to have both its 1% and 10% boundaries modified by the term “about.” Further, it is understood that when a quantity of a component is given, it is intended to mean the amount of active material, unless expressly stated otherwise.

Although the numerical ranges and parameters within the general scope of the disclosure are approximations, unless otherwise indicated, the numerical values presented in the specific examples are reported as accurately as possible. However, any numerical value inherently contains some errors necessarily resulting from the standard deviation observed in their respective test measurements. The following example serves to illustrate embodiments of the present disclosure without being limiting in nature.
