Description

The present patent application relates the reinforcement the cleaning performance of detergents when washing textiles through the use of a combination of dirt-releasing cellulose derivative and hygroscopic polymer.

In addition to the ingredients that are indispensable for the washing process, such as surfactants and builder materials, detergents generally contain other ingredients, which can be summarized under the term washing aids and which include such different active ingredient groups as foam regulators, graying inhibitors, bleaching agents, bleach activators and color transfer inhibitors. Such auxiliary substances also include substances which impart dirt-repellent properties to the laundry fiber and which, if present during the washing process, support the dirt-removing ability of the other detergent components. The same applies analogously to cleaning agents for hard surfaces. Such soil release agents are often referred to as "soil release" actives or because of their ability to make the treated surface, for example the fiber, dirt repellent, "soil repellents". For example, from the US patent US 4 136 038 known the dirt-releasing effect of methyl cellulose. The European patent application EP 0 213 729 discloses the reduced redeposition when using detergents which contain a combination of soap and nonionic surfactant with alkyl-hydroxyalkyl-cellulose.

The U.S. patent US 4,000,093 discloses detergents which contain 0.1% by weight to 3% by weight of alkyl cellulose, hydroxyalkyl cellulose or alkyl hydroxyalkyl cellulose and 5% by weight to 50% by weight of surfactant, the surfactant component essentially consists of C ₁₀ to C ₁₃ alkyl sulfate and has up to 5% by weight of C _{1 4} alkyl sulfate and less than 5% by weight of alkyl sulfate with alkyl radicals of C ₁₅ and higher. The U.S. patent US 4,174,305 discloses detergents which contain 0.1% by weight to 3% by weight of alkyl cellulose, hydroxyalkyl cellulose or alkyl hydroxyalkyl cellulose and 5% by weight to 50% by weight of surfactant, the surfactant component essentially consists of C ₁₀ - to C _{1 2} -alkylbenzenesulfonate and has less than 5% by weight of alkylbenzenesulfonate with alkyl radicals of C _{1 3} and higher. The European patent application EP 0 634 481 relates to a detergent containing alkali percarbonate and one or more nonionic cellulose derivatives. Are disclosed expressly latter only hydroxyethyl cellulose, hydroxypropyl cellulose and methyl cellulose, as well as - in the examples - the methyl hydroxyethyl cellulose Tylose ^® MH50, the hydroxypropyl methyl cellulose Methocel ^® F4M, and hydroxybutyl methylcellulose. The European patent specification EP 0 271 312 (P&G) relates to dirt-releasing active ingredients, among them cellulose alkyl ether and cellulose hydroxyalkyl ether (with DS 1.5 to 2.7 and molecular weights from 2000 to 100000) such as methyl cellulose and ethyl cellulose, which are mixed with peroxygen bleach in a weight ratio (based on the active oxygen content of the bleach) of 10: 1 to 1:10 should be used. From the European patent specification EP 0 948 591 B1 a detergent in liquid or granular form is known which gives fabrics and textiles which are washed therewith, textile appearance advantages such as Pi11 / lint reduction, anti-color fading, improved abrasion resistance and / or increased softness and the 1 to 80% by weight surfactant, 1 to Contains 80 wt .-% organic or inorganic builder, 0.1 to 80 wt .-% of a hydrophobically modified nonionic cellulose ether with a molecular weight of 10,000 to 2,000,000, the modification in the presence of optionally oligomerized (degree of oligomerization up to 20 ) Ethyleneoxy or 2-propyleneoxy ether units and of C _8-24 alkyl substituents and the alkyl substituents must be present in amounts of 0.1-5 wt .-%, based on the cellulose ether material.

Because of their chemical similarity particularly effective for polyester fibers in textiles made from this material active substances capable of releasing dirt are copolyesters, the Dicar acid units, Contain alkylene glycol units and polyalkylene glycol units. Soil-removing copolyesters the type mentioned as well as their use in detergents have been known for a long time.

For example, the German published specification DT 16 17 141 a washing process using polyethylene terephthalate-polyoxyethylene glycol copolymers. The German publication DT 22 00 911 relates to detergents which contain nonionic surfactant and a copolymer of polyoxyethylene glycol and polyethylene terephthalate. In the German patent application DT 22 53 063 acidic textile finishing agents are mentioned which contain a copolymer of a dibasic carboxylic acid and an alkylene or cycloalkylene polyglycol and optionally an alkylene or cycloalkylene glycol. Polymers made from ethylene terephthalate and polyethylene oxide terephthalate, in which the polyethylene glycol units have molecular weights from 750 to 5000 and the molar ratio of ethylene terephthalate to polyethylene oxide terephthalate is 50:50 to 90:10, and their use in detergents are described in the German patent DE 28 57 292 described.

The European patent EP 066 944 relates to textile treatment agents which contain a copolyester of ethylene glycol, polyethylene glycol, aromatic dicarboxylic acid and sulfonated aromatic dicarboxylic acid in certain molar ratios. From the European patent EP 185 427 are known methyl- or ethyl group-end-capped polyesters with ethylene and / or propylene terephthalate and polyethylene oxide terephthalate units and detergents which contain such a soil release polymer. The European patent EP 241 984 relates to a polyester which, in addition to oxyethylene groups and terephthalic acid units, also contains substituted ethylene units and glycerol units. From the European patent EP 241 985 Polyesters are known which, in addition to oxyethylene groups and terephthalic acid units, contain 1,2-propylene, 1,2-butylene and / or 3-methoxy-1,2-propylene groups and glycerol units and are end-capped with C ₁ -C ₄ -alkyl groups are. The European patent specification EP 253 567 relates to soil-release polymers with a molecular weight of 900 to 9000 made of ethylene terephthalate and polyethylene oxide terephthalate, the polyethylene glycol units having molecular weights of 300 to 3000 and the molar ratio of ethylene terephthalate to polyethylene oxide terephthalate being 0.6 to 0.95. From the European patent application EP 272 033 are known at least partly by C _1-4 alkyl or acyl residues end-capped polyesters with polypropylene terephthalate and polyoxyethylene terephthalate units.

From the German patent specification DE 28 46 984 Detergents are known which contain a reaction product of a polyester with a prepolymer containing terminal isocyanate groups, obtained from a diisocyanate and a hydrophilic nonionic macrodiol, as the dirt-removing polymer.

The majority of this extensive Polymers known in the prior art have the disadvantage that they are Textiles that are not or at least not predominantly made of polyester exist, have no or insufficient effectiveness. On greater Part of today's textiles, however, consists of cotton or cotton-polyester blends the existence Need for greasy soiling on such textiles more effective soil release polymers consists.

Surprisingly it has now been found that the dirt-removing effect of cellulose derivatives can be improved when combined with hygroscopic polymer.

The object of the invention is therefore the use of a combination of soil release cellulose derivative, the available is by alkylation and hydroxyalkylation of cellulose, and hygroscopic polymer to enhance cleaning performance of detergents when washing textiles.

Preferred cellulose derivatives are those which are alkylated with C ₁ to C ₁₀ groups, in particular C ₁ to C ₃ groups, and additionally carry C ₂ to C ₁₀ hydroxyalkyl groups, in particular C ₂ to C ₃ hydroxyalkyl groups. These can be obtained in a known manner by reacting cellulose with appropriate alkylating agents, for example alkyl halides or alkyl sulfates, and then reacting with corresponding alkylene oxides, such as ethylene oxide and / or propylene oxide. In a preferred embodiment of the invention, the cellulose derivative contains on average 0.5 to 2.5, in particular 1 to 2, alkyl groups and 0.02 to 0.5, in particular 0.05 to 0.3, hydroxyalkyl groups per anhydroglycosomer monomer unit. The average molecular weight of the cellulose derivatives used according to the invention is preferably in the range from 10,000 D to 150,000 D, in particular from 40,000 D to 120,000 D and particularly preferably in the range from 80,000 D to 110,000 D. The degree of polymerization or the molecular weight is determined of the dirt-releasing cellulose derivative is based on the determination of the intrinsic viscosity of sufficiently dilute aqueous solutions using an Ubbelohde capillary viscometer (capillary 0c). Using a constant [H. Staudinger and F. Reinecke, "About molecular weight determination on cellulose ethers", Liebigs Annalen der Chemie 535, 47 (1938)] and a correction factor [F. Rodriguez and LAGoettler, "The Flow of Moderately Concentrated Polymer Solutions in Water", Transactions of the Society of Rheology VIII, 3 17 (1964)] can be used to calculate the degree of polymerization and the corresponding molecular weight, taking into account the degrees of substitution (DS and MS).

Hygroscopic is the term for the property of many substances to attract air humidity when stored in air for a long time. In contrast to substances that accumulate water (and form hydrates), hygroscopic substances are normally decomposed when stored in the air for a long time. Examples of hygroscopic polymers are sugar alcohols (e.g. starch), polypeptides (e.g. gelatin, polyaspartate), polyvinylpyrrolidone, polyvinyl alcohol, polyacrylic acid and derivatives of polyacrylic acid or polymers of derivatives of acrylic acid, such as poly (acrylic acid) sodium salt, poly (hydroxyacrylic acid), poly (acrylic acid-co-allyl alcohol), poly (4-methoxytetramethylene-1,2-dicarboxylic acid), poly (tetramethylene-1,2-dicarboxylic acid), polyacrylic acid-co-maleic acid sodium salt, poly (acrylic acid-co-ethylene glycol diglycidyl ether , N, N'-methylenebisacrylamide-sodium acrylate copolymer with hexaphosphonic acid and polyalkylene glycols, particularly in the latter case the hygroscopic character is a function of the hydroxyl groups and decreases with increasing Molecular weight and increasing number of ether bonds (e.g. polyethylene glycol dimethylacrylate). So-called hydrogels, ie hydrophilic polymers, which absorb water but are largely insoluble in water due to their three-dimensional network, can also be used as hygroscopic polymers. Examples of such hydrogels are agarose, the polymerization products of dimethylacrylamide or glycerol methacrylate, the copolymerization products of hydrophilic monomers such as hydroxyethyl methacrylate and hydroxypropyl methacrylate with very hydrophilic ionic monomers such as methacrylic acid, crosslinked polyoxazolines, crosslinked polyesters from fumaric acid and polyethylene glycol with N-vinylpyrrolidone, sulfonate. Other examples of hygroscopic polymers are ε-caprolactam-polyethylene glycol-terephthalic acid block copolymers, unsaturated amide-substituted ether compounds and polyphosphoric diesters and triesters. The hygroscopic polymer is preferably selected from polyvinylpyrrolidone, polyvinyl alcohol, the polyalkylene glycols and / or the homopolymers of acrylic acid, methacrylic acid and maleic acid and copolymers thereof, polyacrylic acids being particularly preferred. The molar masses of these are preferably in the range from 500,000 D to 700,000 D, in particular from 550,000 D to 650,000 D.
