Description

COMPOSITION RESISTANT TO THE FORMATION OF WRINKLES TECHNICAL FIELD OF THE INVENTION The present invention relates to compositions for fabric care and to a method for treating fabrics in order to improve various properties thereof, in particular the resistance to wrinkling.

BACKGROUND OF THE INVENTION Domestic fabric treatment is a problem known in the art by the formulator of laundry compositions. Therefore, it is well known that alternating cycles of using and washing fabrics and textiles, such as articles of clothing and clothing that have been used, will inevitably adversely affect the appearance and integrity of the fabric and washed textile articles. and used in this way. Fabrics and textiles simply wear out over time and with use. The washing of fabrics and textiles is necessary to eliminate the stains and dirt that accumulate on them and on them during common use. However, the washing operation itself, through many cycles, can accentuate and contribute even more to the deterioration of the integrity and appearance of such fabrics and textiles. A solution for improving the appearance and integrity of fabrics can be found in WO98 / 04772, which provides the treatment of fabrics against wrinkling therein by applying a composition comprising a polycarboxylic acid or a derivative thereof; and then curing the composition used a domestic procedure. However, it has been found that although they are effective in reducing wrinkling, the compounds described in this patent still do not effectively bind to the cellulosic fibers in the rinse application. Accordingly, it is an object of the invention to provide compounds and compositions thereof that provide an effective deposition on the fabric without being detrimental to the appearance and integrity thereof. In particular, it is an object of the invention to provide compounds or compositions having effective permanent press properties. The problem of permanent ironing in the industrial field is known in the art. The procedures for the industrial treatment of permanent ironing of textile fabrics were introduced for the first time in the decade of the 1960s and have achieved widespread use since then. These permanent ironing treatment processes typically involve treating the fibers of the textile fabrics with crosslinking agents. Previous permanent ironing procedures used formaldehyde as a crosslinking agent which, although effective, has a strong odor and is not desirable by consumers.

As a consequence, the formaldehyde was replaced with reactive resins such as dimethylol urea (DMU), dimethylol ethylene urea (DMEU), and with modified ethyl urea resins, such as dimethylol dihydroxy ethylene urea (DMDHEU). However, it is still known that the desired increases in the performance of permanent press by the use of crosslinking agents is sometimes accompanied by unwanted losses in other important properties of the fabric, such as tensile strength, resistance to tear, resistance to abrasion and touch of the fabric. In addition, the solutions obtained from the industry usually can not be transposed to domestic treatments. In fact, in industrial processes strict control is possible on parameters such as pH, electrolyte concentration, water hardness, temperature, etc., while in a domestic washing machine, such a high level of control is not possible. In addition, it has been found that industrial solutions do not bind effectively to cellulose fibers in domestic rinse applications. Permanent domestic ironing treatments require conditions that industrial treatment does not have to meet. Thus, for domestic permanent ironing treatments, the compounds or compositions thereof need to manifest at least one of the following properties: i) .- that provides a low level of aldehyde; in effect, aldehyde-based cross-linking technologies are less favored in domestic procedures from an environmental and safety point of view because, contrary to the industry in which the procedure is controlled, in domestic procedures the consumer is the only person who uses the product, thus allowing the possibility of misuse. In addition, high levels of aldehyde tend to produce an odor that could prevent the consumer from using it again. Therefore, it is desired to provide permanent ironing procedures to be used in domestic procedures that are safe for the consumer and that provide a good acceptance of the odor. ii) .- that provides a very low or even no loss of tensile strength; again as established above for i), the control of the procedure in the domestic treatment is less measurable. In addition, contrary to the industry in which fabrics are treated only once, domestic treatment involves repeated use and thus a loss in tensile strength occurs. Therefore, if it is desired to provide permanent ironing procedures for use in a domestic process that provides low or even no loss of tensile strength. iii) .- that can be used at low temperature; in fact in a domestic process, and in particular in a domestic rinse procedure, it is not practical to rely on high treatment temperatures such as those used in industrial processes, ie temperatures above 40 ° C. Therefore, it is also a desire for permanent domestic ironing to provide better performance at these low temperatures; In reality, the industry normally obtains a better performance through the close control of the reaction process and its various parameters involved. However, in the domestic treatment, this close control can not be obtained. Therefore, the performance of the permanent press procedure needs to be obtained for the most part using efficient technology. iv) .- that can be used in rinsing applications: in such type of application, an easier control of the use of the product is achieved, thereby avoiding misuse. Thus, for domestic treatment, it is necessary that the technology involved in the permanent ironing process is preferably appropriate to be used in the application of rinsing, and / or v) .- that does not provide rigidity to the fabrics. Again, as described for ii), repeated use which is involved in the domestic treatment can also lead to rigid fabrics. Accordingly, it is desired to provide permanent ironing procedures that reduce such negative aspect. In addition to the above, industrial processes use high concentrations of crosslinking agents that are necessary for the treatment on an industrial scale while for domestic treatment a low level is preferred for reasons of economy. Accordingly, despite advances in the art, there remains a need for an effective and economical composition that provides effective permanent household ironing properties in the treated fabrics. It has now been discovered that the use of specific resin compounds satisfies such a need, and they are particularly well suited for application in rinsing.

BRIEF DESCRIPTION OF THE INVENTION The present invention is a composition comprising: i) a fabric softening compound; and ii) a crosslinking resin having the property of being cationic. In another aspect of the invention, the present invention relates to a method for the treatment of fabrics comprising the steps of: i) contacting the fabrics with epichlorohydrin adducts of polyamine-type resins, polyethylene imine-type resins, cationic starch , polydiallyldimethylammonium chloride and mixtures thereof, and ii) curing the composition.

In a further aspect of the invention, the present invention relates to a method for treating fabrics comprising the steps of: i) contacting the fabrics with a resin compound or composition such as defined herein, and I) Curing the composition using a domestic procedure.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to compositions that provide effective permanent ironing on treated fabrics, especially when treated in a rinse application.

Crosslinking resin having the property of being cationic An essential component of the invention is a crosslinking resin having the property of being cationic. With "crosslinking resin having the property of being cationic" it is meant that the resin is at least partially charged with positive charges. However, it is not necessary for the reactive part of the molecule to carry the positive charge. In effect, the polymeric resins can be based on monomers having positive charges which aid in the deposition on the fibers. Because the crosslinking resins are cationic, that is they have positive charges, they are deposited and are well retained in the cellulosic fibers which have negative charges when these resins are added in the final rinse of a laundry procedure. The crosslinking resins which have the property of being cationic appropriate for use in the present invention are those commonly known in the field of papermaking for having wet strength. At least two mechanisms have been postulated to explain the mechanism by which the wet strength resin acts. One of the mechanisms is that the resins for wet strength form covalent bonds between the adjacent fibers, while the other postulates that the wet strength resin places a layer on the hydrogen bonds formed between the adjacent paper fibers avoiding this way that water dissociates the hydrogen bonds. Strength agents conventional wet suitable for use herein include compounds made from adducts of epichlorohydrin polyamine, polyethyleneimines, cationic starches, polydiallyldimethylammonium and mixtures thereof chloride resins, amino-aldehydes such as the melamine-formaldehyde resin, amide-aldehyde-type resins and mixtures thereof. For use within the meaning of the present invention, it is also possible to use materials of the aforementioned classes of substances which, obviously, do not possess by themselves any wet strength properties but which nevertheless have the same effect of permanent ironing than that of wet strength agents as described in the present invention. Among the classes of adducts of epichlorohydrin polyamine, polyethyleneimines, cationic starches, polydiallyldimethylammonium chloride, and mixtures thereof, the preferred components are resins amine-epichlorohydrin polymer selected from the group consisting of epichlorohydrin polyamide-type resin (PAE), a type polyalkylenepolyamine-epichlorohydrin (PAPAE) resin, and a type amine polymer-epichlorohydrin (APE) resin, in which amine groups have been alkylated with epichlorohydrin to produce a polyamine-epichlorohydrin type having groups functional azetidinium or epoxide. Preferably, for use in the present invention, the crosslinking resin having cationic properties it is a resin wet strength cationic produced by reacting an aliphatic dicarboxylic acid, saturated containing three to ten carbon atoms with a polyalkylenepolyamine , containing from two to four ethylene groups, two primary amine groups, and one to three secondary amine groups (such as diethylenetriamine, triethylenetetramine and tetraethylenepentamine) to form a poly (aminoamide) having secondary amine groups that are alkylated with epichlorohydrin to form a PAE resin. These wet strength polyamide / polyamine / epichlorohydrin resins are fully described by Carr, Doane, Hamerstrand and Hofreiter, in an article appearing in the Journal of Applied Polymer Science vol. 17, pp. 721-735 (1973). Such resins can be obtained as KYMENE from Hercules, Inc. A commercial synthesis of such resins from adipic acid, diethylenetriamine and epichlorohydrin is described in the publication of Carr et al., Ibid. And in the patent E.U.A. No. 2,926,154 (February 23, 1960) for G.l. Keim or in the patent E.U.A. No. 4,240,995. Reference may be made to these publications for additional details regarding the preparation of the polyamide / polyamine / epichlorohydrin resins. Crosslinking resins having more preferred cationic properties of this class are the Kymene 557H wet strength resins (available from Hercules Incorporated), in which adipic acid is reacted with diethylenetriamine to form a poly (aminoamide) which is alkylated and crosslinked with epichlorohydrin to form a PAE resin. Even other crosslinking resins having preferred cationic properties made from epichlorohydrin are Luresin.RTM and Etadurin resins of which both are polyamidoamine-epichlorohydrin type resins. Amine-aldehyde type resins are crosslinking resins suitable for the present invention and are made by condensation of the amine or amine monomers with aldehydes such as formaldehyde and glyoxal. Preferred amines are those having low molecular weight amines, for example melamine or polymeric amines, for example polydiallylamine, preferably quaternized. The Preferred amides are those polymeric amides such as polyacrylamide. All these appropriate amine / amide monomers can also be copolymerized with cationic monomers. Among the class of amine-aldehyde crosslinking resins, those of the melamine-formaldehyde type resin class are preferred. Melamine-formaldehyde resins of this type are known as crosslinking agents of this type in the coatings industry and are also described, for example, in the German Auslegeschrift documents. 2,457,387 (U.S. Patent No. 4,035,213 incorporated for reference in the present invention) and 1,719,324 and, in particular, in the U.S.A. No. 3,242,230 incorporated for reference in the present invention. Preferred melamine-formaldehyde resins are those that are commercially available under the trade names Madurit and Cassurit from Clariant. Even other crosslinking resins which have the property of being cationic preferred among the class of amine-aldehyde crosslinking resins are the poly (acrylamide-glyoxal) type resins which are commercially available under the trade name SOLIDURIT KM from Clariant. In accordance with the present invention, a mixture of wet strength agents of the aforementioned types or equivalent compounds can also be used.

Preferably, for the purposes of the invention, the crosslinking resin having the property of being cationic has a molecular weight between 200 and 1,000,000, more preferred between 500 and 100,000, more preferred even between 1,000,000 and 25,000. Crosslinking resins having a low molecular weight are most preferred for use in the present invention since they are more water soluble and have better fiber penetration. With "low molecular weight" is meant a molecular weight in the range of from 25 to 2,000, preferably from 50 to 1,000, and more preferred from 50 to 500. The above crosslinking components can be used in a composition for delivery over the fabric, such as by a rinse procedure. It is desired that the level of crosslinking components or derivatives thereof be present in an amount from 0.01% to 60%, preferably from 0.01% to 30% by weight of the total composition. It is advantageous to use a catalyst, for crosslinking resins containing aldehyde, with the compositions of the invention. Preferred catalysts include organic acids such as citric acid, succinic acid and tartaric acid, as well as conventional Lewis acids such as AICI3 or MgC, or salts thereof, or mixtures thereof. A typical catalyst example is the NKD catalyst made from a mixture of salts and organic acid, which can be obtained commercially from Hoechst.

It is preferred that the level of catalyst be from 10% to 50%, preferably from 20 to 40% by weight of the crosslinking components or derivatives thereof. For other crosslinking resins such as Kymene resins, it is not necessary to use a catalyst.

Fabric Softening Compound The composition of the invention also contains a fabric softening compound. Typical incorporation levels of the fabric softening compound in the composition are from 1% to 80% by weight, preferably from 2% to 70%, more preferred from 5% to 60% by weight of the composition. The quaternary ammonium compounds or the amine precursors thereof are typical of the cationic softening agents as defined below in the present invention.

A) Quaternary ammonium fabric softening active compound 1) The preferred quaternary ammonium fabric softening active compound has the formula: ( 1 ) or the formula: where Q is a carbonyl unit that has the formula: each R unit is independently hydrogen, C-i-Cß alkyl, d-Cβ hydroxyalkyl and mixtures thereof, preferably methyl or hydroxyalkyl; each R1 unit is independently linear or branched C11-C22 alkyl, linear or branched C11-C22 alkenyl and mixtures thereof; R 2 is hydrogen, C 1 -C 4 alkyl, C 1 -C 4 hydroxyalkyl and mixtures thereof; X is an anion that is compatible with active fabric softeners and adjunct ingredients; the index m is from 1 to 4, preferably 1; the index n is from 1 to 4, preferably 2. An example of a fabric softening active that is preferred is a mixture of quaternized amines having the formula: R wherein R is preferably methyl; R1 is a linear or branched alkyl or alkenyl chain comprising at least 11 carbon atoms, preferably at least 15 atoms. In the above fabric softener example, the -O2CR1 unit represents an acyl unit of fatty acid which is typically obtained from a source of triglycerides. The source of triglycerides is preferably derived from tallow, partially hydrogenated tallow, lard, partially hydrogenated butter, vegetable oils and / or partially hydrogenated vegetable oils, such as canola oil, safflower oil, peanut oil, sunflower oil, oil of corn, soybean oil, wood oil, rice bran oil, etc. and mixtures thereof.

The fabric softening actives which are preferred in the present invention are the diester and / or quaternary ammonium diamide compounds (DEQA), the diesters and diamides having the formula: wherein R, R1, X and n are the same as defined above in the present invention for formulas (1) and (2), and Q has the formula: O H O II -o - c- -N I - C II These preferred fabric softening actives are formed from the reaction of an amine with an acyl unit of fatty acid to form an amine intermediate having the formula: wherein R is preferably methyl, Q and R1 are as defined above in the present invention; followed by quaternization until the final softening active. Non-limiting examples of the preferred amines that are used to form the fabric softening actives of DEQA according to the present invention include methyl-bis (2-hydroxyethyl) amine having the formula: methyl-bis (2-hydroxypropyl) amine having the formula: methyl- (3-aminopropyl) (2-hydroxyethyl) amine having the formula: methyl-bis (2-aminoethyl) amine having the formula: triethanolamine that has the formula: di (2-aminoethyl) ethanolamine having the formula: The above X (_) counter ion can be any anion compatible with softener, preferably the anion of a strong acid, for example, chloride, bromide, methylisulfate, etiisulfate, sulfate, nitrate and the like, more preferred chloride or methylisulfate. The anion can also, but is less preferred, carry a double charge in which case X (_) represents half of a group. Sebum and canola oil are convenient and inexpensive sources of fatty acid acyl units which are suitable for use in the present invention as R1 units. The following examples are non-limiting examples of quaternary ammonium compounds suitable for use in the compositions of the present invention.

The term "seboyl" as used later in the present invention indicates that unit R1 is obtained from a source of tallow triglycerides and is a mixture of alkyl or alkenyl units of fatty acid. Likewise, the use of the term canolyl refers to a mixture of alkyl or alkenyl units of fatty acid obtained from canola oil. The following table describes non-limiting examples of fabric softeners appropriate according to the above formula. In O this list, the term "oxi" defines a unit, while the term "oxo" defines a unit -O-.

TABLE I Fabric softening assets N, N-di (tallowyloxy-2-oxo-ethyl) -N-methyl, N- (2-hydroxyethyl) ammonium chloride; N, N-di (canolyl-oxy-2-oxo-ethyl) -N-methyl, N- (2-hydroxyethyl) ammonium chloride; N, N-di (tallowoyloxy-2-oxo-ethyl) -N, N-dimethylammonium chloride; N, N-di (canolyoxy-2-oxo-ethyl) -N, N-dimethylammonium chloride; N, N, N-tri (tallowyloxy-2-oxo-ethyl) -N-methylammonium chloride; N, N, N-tri (canolyl-oxy-2-oxo-ethyl) -N-methylammonium chloride; N- (tallowoyloxy-2-oxo-ethyl) -N- (tallowyl) -N, N-dimethylammonium chloride; N- (caninoxy-2-oxo-ethyl) -N- (canolyl) -N, N-dimethylammonium chloride; Chloride e 1, 2-di (tallowoyloxy-oxo) -3-N, N, N-trimethylammoniopropane; Y 1, 2-di (canolyloxy-oxo) -3-N, N, N-trimethylammoniopropane chloride; and mixtures of the above assets. Other examples of quaternary ammonium softening compounds are methylbis (tallowamidoethyl) (2-hydroxyethyl) ammonium methylisulfate and methylbis (hydrogenated tallow-amidoethyl) (2-hydroxyethyl) ammonium methylisulfate; these materials are available from Witco Chemical Company under the tradenames Varisoft® 222 and Varisoft® 110, respectively. N, N-di (tallowyloxy-2-oxo-ethyl) -N-methyl, N- (2-hydroxyethyl) ammonium chloride in which the tallow chains are at least partially unsaturated is particularly preferred. The level of saturation contained within the chain of the acyl unit of tallow, canola or other chain of acyl unit of fatty acid can be measured by the Iodine Value (IV) of the corresponding fatty acid, which in the present case should be preferably in the range of 5 to 100, distinguishing two categories of compounds having an IV below or above 25. In effect, for compounds having the formula: Fatty acid derivatives of tallow, it has been found that, when the Iodine Value is from 5 to 25, preferably 15 to 20, a weight ratio of cis / trans isomer greater than about 30/70, preferably greater than about 50/50 and more preferred greater than about 70/30, provides optimum concentration ability. It has been found that, for compounds of this type made from tallow fatty acids having an Iodine Value of more than 25, the ratio of cis to trans isomers is less critical, unless very high concentrations are required. . Other suitable examples of fabric softening actives are obtained from fatty acid acyl groups in which the terms "seboyl" and "canolyl" in the above examples are replaced by the terms "cocoyl, palmyl, lauryl, oleyl, ricinoleyl, stearyl, palmityl ", which correspond to the source of triglycerides from which the acyl units of fatty acid are derived. These alternative fatty acid acyl sources can comprise either fully saturated chains, or preferably at least partially unsaturated chains. As described above in the present invention, the R units are preferably methyl, however, suitable fabric softening actives are described by replacing the term "methyl" in the above examples of Table II with the units "ethyl, ethoxy, propyl, propoxy, isopropyl, butyl, isobutyl and t-butyl ". The X-counter ion in the examples of Table II can be appropriately replaced with bromide, methylisulfate, formate, sulfate, nitrate and mixtures thereof. In fact, the X anion is simply present as a counter ion of the positively charged quaternary amino compounds. The scope of this invention is not considered limited to any particular anion. For the above ester fabric softening agents, the pH of the compositions of the present invention is an important parameter of the present invention. In effect, this influences the stability of the quaternary ammonium compounds or amine precursors, especially under conditions of prolonged storage. As used in the present invention, when the diester is specified, it will include the monoester which is normally present during manufacture. For smoothing, under non-entrained laundry / low detergent wash conditions, the monoester percentage should be as low as possible, preferably not more than about 2.5%. However, under conditions of high detergent drag, a certain amount of monoester is preferred. The general ratios of diester to monoester are from about 100: 1 to about 2: 1, preferably from about 50: 1 to about 5: 1, more preferred from about 13: 1 to about 8: 1. Under conditions of high detergent carryover, the di / monoester ratio is preferably about 11: 1. The level of monoester present can be controlled during the manufacture of the softening compound.

Mixtures of the active ingredients of the formula can also be prepared (i) and (2). 2) Even other quaternary ammonium fabric softening compounds suitable for use in the present invention are the cationic nitrogenous salts having two or more long-chain aliphatic and non-cyclic Cs-C22 hydrocarbon groups, or one such group and one Arylalkyl group, which may be used alone or as part of a mixture, are selected from the group consisting of: (i) non-cyclic quaternary ammonium salts having the formula: wherein R4 is a non-cyclic and aliphatic C8-C22 hydrocarbon group, R5 is an alkyl or hydroxyalkyl group of saturated CrC, R8 is selected from the group consisting of groups R4 and R5, and A- is an anion as defined previously; (ii) diamino alkoxylated quaternary ammonium salts having the formula: wherein n is equal to 1 to about 5, and R1, R2, R5 and A "are as defined above; (ii) mixtures thereof Examples of the cationic nitrogenous salts of the above class are the well-known ones dialkyldimethylammonium salts such as ditallowdimethylammonium chloride, ditallowdimethylammonium methylisulfate, di (hydrogenated tallow) dimethylammonium chloride, distearyldimethylammonium chloride, dibehenyldimethylammonium chloride Di (hydrogenated tallow) dimethylammonium chloride and ditallowdimethylammonium chloride are preferred Examples of dialkyldimethylammonium salts commercially useful in the present invention are di (hydrogenated tallow) dimethylammonium chloride (trade name Adogen® 442), ditallowdimethylammonium chloride (trade name Adogen®470, Praepagen® 3445), distearyldimethylammonium chloride (trade name Arosurf® TA-100) ), all available from Witco Chemical Company.Dibehenyldimethylammonium chloride is sold under the trade name ial Kemamine Q-2802C by Humko Chemical Division of Witco Chemical Corporation. Dimethylstearylbenzylammonium chloride is sold under the trade names Varisoft® SDC by Witco Chemical Company and Ammonyx® 490 by Onyx Chemical Company.

The additional fabric softening agents useful in the present invention are described in U.S. Patent No. 4,661, 269, issued April 28, 1987, to the names of Toan Trinh, Errol H. Wahl, Donald M. Swartley and Ronald L. Hemingway; the patent of E.U.A No. 4,439,335, Burns, issued March 27, 1984; and the patent of E.U.A No. 3,861, 870, Edwards and Diehl; 4,308,151, Cambre; 3,886,075, Bernardino; 4,233,164, Davis; 4,401, 578, Verbruggen; 3,974,076, Wiersema and Rieke; 4,237,016, Rudkin, Clint and Young; and the publication of European patent application No. 472,178, by Yamamura, et. to the.; all those documents incorporated in the present invention as reference. Of course, the term "softening active" may also encompass mixed softening active agents. Among the classes of softening compounds that are preferred described above in the present invention are the fabric softening active compound of diester or quaternary ammonium diamide (DEQA). Fully formulated softening compositions preferably contain, in addition to the compounds described above in the present invention, one or more of the following ingredients.

OPTIONAL INGREDIENTS (1) Liquid vehicle Another optional, but preferred, ingredient is a liquid vehicle.

The liquid vehicle used in the present compositions is preferably at least mostly water due to its low cost, relative availability, safety and compatibility with the environment. The water level in the Liquid carrier is preferably at least 50%, more preferred at least 60%, by weight of the vehicle. Mixtures of water and low molecular weight organic solvent, for example < Approximately 200, for example lower alcohols such as ethanol, propanol, isopropanol or butanol are useful as the liquid carrier. Low molecular weight alcohols include monohydric, dihydric (glycol, etc.), trihydric (glycerol, etc.) alcohols and polyhydric higher alcohols (polyols). (2) Scatter Ability Aids Relatively concentrated compositions can be prepared containing saturated and unsaturated quaternary ammonium diester compounds that are stable without the addition of concentration aids. However, the compositions of the present invention may require organic and / or inorganic concentrating aids to obtain still higher concentrations and / or to satisfy higher stability standards, depending on the other ingredients. These concentration aids which typically can be viscosity modifiers may be necessary, or preferred, to ensure stability under extreme conditions when particular levels of softening active are used. The surfactant concentration aids are typically selected from the group consisting of (1) individual long chain alkyl cationic surfactants; (2) nonionic surfactants; (3) amine oxides; (4) fatty acids and (5) mixtures thereof.

These auxiliaries are described in WO 94/20597, specifically on page 14, line 12 to page 20, line 12, which is incorporated in the present invention for reference. When said dispersion capacity auxiliaries are present, the total level is from 0.1% to 20%, preferably from 0.2% to 10%, more preferred from 0.5% to 5% and even more preferred from 1% to 2% by weight of the composition. These materials can be added either as part of the raw material of the active softener, (I), for example, the long-chain alkyl cationic surfactant and / or the fatty acid which are reactants used to form the softening active of biodegradable fabrics as described above in the present invention, or are added as a separate component. The total dispersion capacity auxiliary level includes any quantity that may be present as part of the component (I). Inorganic viscosity control / dispersion-ability agents that can also act the same or increase the effect of surfactant concentration aids, include water-soluble ionizable salts that can also be optionally incorporated into the compositions of the present invention. A wide variety of ionizable salts can be used. Examples of suitable salts are the metal halides of groups IA and HA of the Periodic Table of the Elements, for example, calcium chloride, magnesium chloride, sodium chloride, potassium bromide and lithium chloride. The available salts are particularly useful during the process of mixing the ingredients to make the compositions of the present invention, and then to obtain the desired viscosity. The amount of ionizable salts used depends on the amount of active ingredients used in the compositions and can be adjusted in accordance with the wishes of the formulator. Typical levels of the salts used to control the viscosity of the composition are from about 20 to about 20,000 parts per million (ppm), preferably from about 20 to about 11,000 ppm, by weight of the composition. Alkylene polyammonium salts can be incorporated into the composition to obtain viscosity control in addition to, or in place of, the above water-soluble ionizable salts. In addition, these agents can act as scavengers, forming ion pairs with the anionic detergent entrained from the main wash, in the rinse and on the fabrics, and can improve the yield of softness. These agents can stabilize the viscosity over a wider temperature range, especially at low temperatures, compared to inorganic electrolytes. Specific examples of alkylene polyammonium salts include L-lysine monohydrochloride and 2-methylpentan-1,5-diammonium dihydrochloride. (3) Stabilizers Stabilizers may be present in the compositions of the present invention. The term "stabilizer", such as it is used in the present invention, includes antioxidants and reducing agents. These agents are present at a level of 0% to about 2%, preferably from about 0.01% to about 0.2%, more preferred from about 0.035% to about 0.1% for antioxidants, and most preferably from about 0.01% to approximately 0.2% for reducing agents.

FORM OF COMPOSITION AND COMPOSITIONS The composition or its individual components can be provided in any suitable form such as spray, foam, gel or any other suitable form for liquid compositions.

Method of use A method for the treatment of fabrics is provided, in particular to provide permanent ironing on the fabric, that is to provide fabrics resistant to wrinkling, comprising the steps of contacting the fabrics with a compound or composition of crosslinking the invention, as defined above in the present invention, and curing the composition subsequently, using a domestic process. By "contacting", it is meant any of the steps that is appropriate to provide a contact of the composition with the fabric. This may include soaking, washing, rinsing and / or sprinkling as well as using a dryer sheet on which the composition is adsorbed. Preferably contacting occurs in the course of a laundry process, preferably a rinse step of a laundry process, which preferably occurs in a temperature range below 30 ° C, preferably between 30 ° C and 30 ° C. and 25 ° C. The domestic curing of the fabric can be caused by the heat used to dry the fabric, for example, by rotary drum drying. Ironing is also particularly advantageous for curing the fabric. Without being limited to the theory, it is believed that the shorter time or the low temperatures used to cure the crosslinking components domestically means that the fabrics become resistant to wrinkling without changing their tactile properties, or folding. Yet another advantage of the present invention is that when epichlorohydrin adducts of polyamine type resins, polyethylene imine type resins, cationic starch or polydiallyldimethylammonium chloride, such as Kymene compounds in particular, are used, domestic curing may be room temperature, that is from 15 to 30 ° C.

Yet another advantage of the aforementioned epichlorohydrin adducts is their potential for use in industrial treatment. Accordingly, a method is also provided for the treatment of fabrics comprising the steps of contacting the fabrics with an epichlorohydrin adduct of polyamine type resins, polyethylene imine type resins, cationic starch or polydiallyldimethylammonium chloride, or mixtures thereof, and after that cure the fabrics. In the preferred method, curing is what is conventionally known in industrial processes as impregnation. The composition of the present invention can also be used as an ironing aid. An effective amount of the composition can be sprayed onto the fabric, wherein said composition should not be sprayed until saturated. The fabric can be ironed at the normal temperature at which s should iron. Even another preferred way of treating fabrics is when the fabric can be sprinkled with an effective amount of the composition, allowing it to dry and then iron, or sprinkle and immediately iron.

EXAMPLE OF SYNTHESIS 1 Preparation of PEI 1800 E? Step A) The ethoxylation is carried out in a 7.5 liter stainless steel autoclave with agitator, equipped for temperature measurement and control, pressure measurement, vacuum and inert gas purging, sampling, and for the introduction of ethylene oxide. as a liquid. A cylinder of -9.06 kg net of ethylene oxide (ARC) is installed to supply ethylene oxide as a liquid by means of a pump to the autoclave with the cylinder placed on a scale to be able to monitor the changes in weight of the cylinder. A 750 g portion of polyethylenimine (PEI) (Nippon Shokubai, Epomin SP-018 having an average listed molecular weight of 1800, equivalent to 0.417 moles of polymer and 17.4 is added to the autoclave. moles of nitrogen functional groups). The autoclave is then sealed and purged of air (applying vacuum to minus 711 mm Hg followed by pressurization with nitrogen at 17.57 kg / cm ^, then ventilating at atmospheric pressure). The contents of the autoclave are heated to 130 ° C while vacuum is applied. After about one hour, the autoclave is charged with nitrogen at approximately 17.57 kg / cm2 while the autoclave is cooled to approximately 105 ° C. Ethylene oxide is then added to the autoclave in increments over time while carefully monitoring the pressure, temperature and flow rate of ethylene oxide in the autoclave. The ethylene oxide pump is turned off and cooling is applied to limit any increase in temperature that results from any reaction exotherm. The temperature is maintained between 100 and 110 ° C while the total pressure is allowed to gradually increase during the course of the reaction. After a total of 750 grams of ethylene oxide has been charged into the autoclave (almost equivalent to one mole of ethylene oxide per PEI nitrogen functional group), the temperature is increased to 110 ° C and the autoclave is left Shake for one more hour. At this point, vacuum is applied to remove any residual ethylene oxide that has not reacted.

Step B) The reaction mixture is then deodorized by passing about 2,831 crr? 3 of inert gas (argon or nitrogen) through a Porous glass for gas dispersion and through the reaction mixture while stirring and heating the mixture to 130 ° C. The final reaction product is cooled slightly and collected in glass containers purged with nitrogen. In other preparations, neutralization and deodorization are achieved in the reactor before discharging the product.

EXAMPLE OF SYNTHESIS 2 Preparation of PEI 1200 Ei Step A) The ethoxylation is carried out in a stainless steel autoclave with stirrer, of 7.56 liters, equipped for measurement and temperature control, pressure measurement, vacuum and inert gas purging, sampling, and for the introduction of ethylene oxide. as a liquid. A cylinder of ~ 9.06 kg net of ethylene oxide (ARC) is installed to supply ethylene oxide as a liquid by means of a pump to the autoclave placing the cylinder on a scale to be able to monitor the changes in weight of the cylinder. A 750 g portion of polyethylenimine (PEI) (having a listed average molecular weight of 1200, equivalents to 0. 625 moles of polymer and 17.4 moles of nitrogen functional groups). The autoclave is then sealed and purged of air (applying vacuum to minus 711 mm Hg followed by application of nitrogen pressure at 17.57 kg / cm ^, then ventilating at atmospheric pressure). The contents of the autoclave are heated to 130 ° C while vacuum is applied. After about an hour, the autoclave is charged with nitrogen at approximately 17.57 kg / cm2 while the autoclave is cooled to approximately 105 ° C. Ethylene oxide is then added to the autoclave in increments over time while carefully monitoring the pressure, temperature and flow rate of ethylene oxide in the autoclave. The ethylene oxide pump is turned off and cooling is applied to limit any increase in temperature that results from any reaction exotherm. The temperature is maintained between 100 and 110 ° C while the total pressure is allowed to gradually increase during the course of the reaction. After a total of 750 grams of ethylene oxide has been charged into the autoclave (almost equivalent to one mole of ethylene oxide per PEI nitrogen functional group), the temperature is increased to 110 ° C and the autoclave is left shake for an additional hour. At this point, vacuum is applied to remove any residual ethylene oxide that did not react.

Step B) The reaction mixture is then deodorized by passing about 2.831 cm3 of inert gas (argon or nitrogen) through a porous glass for gas dispersion and through the reaction mixture while stirring and heating the mixture to 130 ° C. .

The final reaction product is cooled slightly and collected in glass containers purged with nitrogen. In other preparations, neutralization and deodorization are achieved in the reactor before discharging the product. If a PEI 1200 E7 is desired, the next step of catalyst addition between Step A and B will be included. Vacuum is applied continuously while the autoclave is cooled to approximately 50 ° C by introducing 376 g of a sodium methoxide solution to 25% in methanol (1.74 moles, to achieve a catalyst load of 10% based on the functional nitrogen groups of PEI). The methoxide solution is sucked into the autoclave under vacuum and then the programming point of the autoclave temperature controller is increased to 130 ° C. A device is used to monitor the energy consumed by the agitator. The power of the agitator is monitored together with the temperature and pressure. The stirrer power and temperature values increase gradually as the methanol is removed from the autoclave, and the viscosity of the mixture increases and stabilizes in about one hour indicating that most of the methanol has been removed. The mixture is heated and further stirred under vacuum for an additional 30 minutes. The vacuum is removed and the autoclave is cooled to 105 ° C while charging with nitrogen at 17.57 kg / cm ^ and then ventilated at ambient pressure. The autoclave is charged to 14.06 kg / cm ^ with nitrogen. Ethylene oxide is added again to the autoclave in increments as mentioned above, carefully monitoring the pressure, temperature and flow velocity of ethylene oxide in the autoclave, while maintaining the temperature between 100 and 110 ° C and limiting any increase in temperature due to the exotherm of the reaction. After achieving the addition of 4,500 g of ethylene oxide (resulting in a total of 7 moles of ethylene oxide per mole of PEI nitrogen functional group) for several hours, the temperature is increased to 110 ° C and the mixture it is stirred for an additional hour. The reaction mixture is then collected in nitrogen-purged containers and optionally transferred to a 22-liter, three-necked ball flask equipped with heating and stirring. The strong alkaline catalyst is neutralized by adding 167 g of methanesulfonic acid (1.74 moles). Other preferred examples such as PEI 1200 E2, PEI 1200 E3, PEI 1200 E15 and PEI 1200 E20 can be prepared by the above method by adjusting the reaction time and the relative amount of ethylene oxide used in the reaction. The invention is illustrated in the following non-limiting examples, in which all percentages are on a weight basis unless indicated otherwise.
