Description

 "Textile Care Agent with Amine Group-Containing Cellulose Ether"

The invention relates to a fabric care composition containing an amine-modified cellulose ether and a washing method for washing textiles using this laundry detergent in a household washing machine. Furthermore, the invention relates to the use of the textile detergent for reducing the creasing, improving the ironing properties and improving the elasticity.

The modern textile cleaning makes high demands on the laundry to be cleaned. For example, the frequent washing of garments in a washing machine and the subsequent drying in a tumble dryer is associated with a high mechanical stress on the fabric. The frictional forces often lead to damage to the textile fabric, recognizable by a fluff and pilling. With each washing or drying cycle, but also by wearing the garments, a further abrasion and / or breakage of tiny fibers takes place on the surface of the textile surface fabrics. The conventional textile cleaners are unable to prevent this damage to the fabric or merely try to eliminate already incurred textile damage.

International patent application WO 99/16956 Al proposes the removal of lint or pills by the use of cellulases. The cellulases thereby break off the microfibers protruding from the textile fabrics and thus ensure a smooth and therefore pilling-free textile surface.

Another major disadvantage of the mechanical stress on textile fabrics is the formation of unwanted wrinkled textile surfaces from the consumer and the formation of rough surfaces. Both the rough textile surfaces as well as the resulting creasing of the fabrics lead to a significant deterioration of the sliding properties of irons or other Textilplättungsvorrichtungen. The cost of flattening rough and wrinkled textiles is not just higher Strengthening effort, but also to see in a considerable time overhead. In the prior art, solutions for improving the ironing properties of laundered textiles are found mainly in the field of aftertreatment agents. For example, International Patent Application WO 00/77134 discloses the use of oxidized polyolefins in softener formulations to improve ironing properties.

The use of celluloses, hydrogels and acrylic acid polymers as lint reduction components in textile treatment agents is known from the German patent application DE 102 03 192 AI.

US Pat. No. 3,472,840 describes quaternary nitrogen-containing cellulose ethers of the general formula (I)

((RO-) ₃ R _C ell) y (I)

in the a and b independently of one another 2 or 3, c 1, 2 or 3, m and p independently of one another an integer from 0 to 10, n an integer from 0 to 3, q 0 or 1, X ^" an anion, which is present in its number in proportion to its charge to balance the positive charges of the quaternary nitrogens, and R 'is hydrogen, a carboxylic acid group, or a sodium, potassium or ammonium carboxylate group, provided that R' is hydrogen when q The compounds of the formula I can be obtained, as described there, by reacting customary or previously specially prepared nonionic cellulose ethers with quaternary halohydrins or quaternary epoxides. Similarly obtained from cellulose ethers by reaction with halogenated alkylamines, epoxyalkylamines or by reaction with Epoxyalkylhalogeniden (eg epichlorohydrin) and subsequent reaction with amines corresponding amine-substituted derivatives in which the nitrogen atoms in the substituent are not quaternized.

Surprisingly, it has now been found that the use of the last-mentioned amine-substituted derivatives without quaternary nitrogen atom in the washing process leads to a significant improvement in the fiber and textile properties.

The present invention therefore relates in a first embodiment to a textile care composition containing nitrogen-containing cellulose ethers of the general formula (I),

((RO-) ₃ R _Ce ") _y (I)

in the Rc _e ii is an anhydroglucose radical (C ₆ Hι ₀ O ₅ ), the degree of polymerization y is a number from 80 to 65 000 and each of the radicals R corresponds to the general formula (II),

- (C _a H _2a -O) _m - (CH ₂ -CH-O) _n - (C _b H _2b -O) _p - (C _c H _2c ) _q -R ³ I (II) CH ₂ -NR ^! R ²

in which a and b are independently 2 or 3, c is 1, 2 or 3, m and p are independently an integer from 0 to 10, n is an integer from 0 to 3, q is 0 or 1, R ¹ and R ² are independently hydrogen or a Cι- ₄ alkyl and R ³ is hydrogen, -NR R, a carboxylic acid group or a sodium, potassium or ammonium carboxylate group, with the proviso that R ³ is hydrogen when q is 0, and the further proviso that in at least one of the radicals R, the number n is greater than 0 or in at least one of the radicals R is the group -R is -NR R.

As stated above, such amine-modified cellulose ethers can be prepared in a simple manner by reaction of at least one hydroxyl group of cellulose and / or hydroxyl-containing cellulose ethers, for example alkyl, hydroxyalkyl or Alkylhydroxyalkylcelluloseethers, with halogenated alkylamines, epoxyalkylamines or first with Epoxyalkylhalogeniden (eg epichlorohydrin) and subsequent reaction with amines, are obtained. In particular, trialkylamines come into consideration as haloalkylamines in which an alkyl group carries a halogen atom, in particular chlorine. Among them, l-diethylamino-2-chloroethane is particularly preferred. As Epoxyalkylhalogenid is in particular epichlorohydrin into consideration, in which case the subsequent reaction with diethylamine is particularly preferred. To avoid a nucleophilic reaction of the amine nitrogen when using halogenated alkylamines or epoxy-alkylamines, this may be in the usual manner in salt form, for example as hydrochloride, so that a neutralization must follow, before the free amines of the general Formula (I) receives.

In the context of this invention, textile care products are understood as meaning both washing and cleaning agents and pretreatment agents and agents for conditioning textile fabrics, such as mild detergents and post-treatment agents, such as fabric softeners. Conditioning is to be understood as the avivating treatment of textile fabrics, fabrics, yarns and fabrics. The purpose of the conditioning is to impart positive properties to the textiles, such as, for example, improved softening, increased gloss and color brilliance, refreshment of fragrances and reduction of creasing behavior and static charge.

When using agents according to the invention in particular the wrinkling of textiles is prevented by the washing and / or drying process, the ironing properties of the textile are improved and the "Ausleiem" of the textiles during washing is considerably reduced. In addition, especially with synthetic fibers, which are otherwise hardly able to absorb moisture such as sweat, for example, the water-holding ability is significantly increased by the use of the agents according to the invention and thus the wearing feeling of the textiles is considerably more pleasant.

The textile care agents according to the invention can be either in solid form, for example as a powder, granules, extrudate, pressed and / or molten molded articles such as tablets, or in liquid form, for example as dispersion, suspension, emulsion, Solution, microemulsion, gel or paste. In a preferred embodiment of the invention, they are liquid. The agents according to the invention preferably comprise 0.1% by weight to 5% by weight, in particular 0.1% by weight to 1% by weight, of amine-modified cellulose ether of the general formula (I). In the compounds of the formula (I), y is preferably in the range from 200 to 35,000, in particular in the range from 800 to 30,000. For each anhydroglucose unit Rc _e ιι, n is preferably 0.01 to 1, in particular 0.1 to 0 , 8, or corresponding numbers of residues R, belonging to the grouping -NR ^! R ² , are present, that is, averaged over the entire cellulose ether is preferably substituted every one-hundredth to each, in particular every tenth to every eighth of tens of Anydroglucose units with a nitrogen atom-bearing group. The sum of m, n, p and q per anhydroglucose unit Rc _e ii is preferably 0.01 to 4, in particular 0.1 to 2 and particularly preferably 0.8 to 2 as the mean value.

In addition to the groups bearing the nitrogen atom, the cellulose ethers to be used according to the invention preferably contain methyl, ethyl, propyl, hydroxyethyl and / or hydroxypropyl groups. These groups represent part of the radicals R and / or are part of the group bearing the nitrogen atom as a subgroup - (CH _2b -O) p- (CcH 2 _C ) q R ³ .

The average molecular weight M w of the cellulose ethers to be used according to the invention is preferably above 5000, more preferably above 10 000, in particular between 30 000 and 1 000 000, advantageously between 50 000 and 800 000 g / mol and most preferably between 200 000 and 600 000 g / mol. The molecular weight can be determined by gel permeation chromatography against standardized polyacrylic acid standards.

In a preferred embodiment of the present invention, the fabric care agents contain complexing agents in addition to the amine-modified cellulose ether. It has surprisingly been found that in particular organic, advantageously water-soluble, complexing agents can be incorporated particularly well into the textile care compositions according to the invention and in particular together with the cellulose ether to be used according to the invention gives the textile care agent, including, in particular the liquid preparations, increased stability. The complexing agents improve the stability of the agents and protect, for example, against the heavy metals catalyzed decomposition of certain ingredients of washing active formulations. Together with the cellulose ether to be used according to the invention, they contribute to the inhibition of incrustations. The group of complexing agents includes, for example, the salts, in particular the alkali metal salts of nitrilotriacetic acid (NTA) and derivatives thereof, and alkali metal salts of anionic polyelectrolytes, such as polymaleates and polysulfonates. Furthermore, citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, sugar acids, aminocarboxylic acids and their derivatives as well as mixtures of these are suitable. Particularly preferred compounds include organophosphonates such as, for example, 1-hydroxyethane-1,1-diphosphonic acid (HEDP), aminotri (methylenephosphonic acid) (ATMP), diethylenetriaminepenta (methylenephosphonic acid) (DTPMP or DETPMP) and 2-phosphonobutane-1,2, 4-tricarboxylic acid (PBS-AM), which are mostly used in the form of their ammonium or alkali metal salts. Particularly preferred in the context of the present invention is the citric acid and / or its alkali metal salts, for example sodium citrate and / or potassium citrate. In a preferred embodiment, the textile care agents contain complexing agents in an amount of up to 20% by weight, preferably from 0.01 to 15% by weight, more preferably from 0.1 to 10 and in particular from 0.3 to 5.0% by weight. -%, Advantageously from 1.5 to 3 wt .-%, each based on the total agent.

In a preferred embodiment, the textile care agents according to the invention additionally comprise nonionic surfactants. The use of nonionic surfactants not only increases the washing performance of the compositions according to the invention, but additionally supports the dispersion and homogeneous distribution of the cellulose ether to be used according to the invention.

As nonionic surfactants are preferably alkoxylated, advantageously ethoxylated and / or propoxylated, in particular primary alcohols having preferably 8 to 18 carbon atoms and an average of 1 to 12 moles of ethylene oxide (EO) and / or 1 to 10 mol Propylene oxide (PO) per mole of alcohol used. Particularly preferred are C ₈ -Cι ₆ - alcohol alkoxylates, advantageously ethoxylated and / or propoxylated C ₁₀ -Ci5 alcohol alkoxylates, in particular -C ₂ -Cι ₄ -Alkoholalkoxylate, with a degree of ethoxylation between 2 and 10, preferably between 3 and 8, and / or a degree of propoxylation between 1 and 6, preferably between 1.5 and 5. The alcohol radical may preferably be linear or more preferably methyl-branched in the 2-position or contain linear and methyl-branched radicals in the mixture, as they are usually present in Oxoalkoholresten. In particular, however, alcohol ethoxylates with linear radicals of alcohols of natural origin having 12 to 18 carbon atoms, for example of coconut, palm, tallow or oleyl alcohol, and on average 2 to 8 EO per mole of alcohol are preferred. The preferred ethoxylated alcohols include, for example Cπ-u-alcohols with 3 EO or 4 EO, C -π-alcohol with 7 EO, C ₁₃ -ι ₅ - alcohols with 3 EO, 5 EO, 7 EO or 8 EO, C _{2 8-} alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of C ₁₂ -i ₄ - alcohol with 3 EO and C ₁₂ -ι ₈ - alcohol with 5 EO. The indicated degrees of ethoxylation and propoxylation represent statistical averages which may be an integer or a fractional number for a particular product. Preferred alcohol ethoxylates and propoxylates have a narrow homolog distribution (narrow ranks ethoxylates / propoxylates, NRE / NRP). In addition to these nonionic surfactants, fatty alcohols with more than 12 EO can also be used. Examples of these are tallow fatty alcohol with 14 EO, 25 EO, 30 EO or 40 EO.

Also suitable are alkoxylated amines, advantageously ethoxylated and / or propoxylated, in particular primary and secondary amines having preferably 1 to 18 C-atoms per alkyl chain and an average of 1 to 12 moles of ethylene oxide (EO) and / or 1 to 10 moles of propylene oxide (PO ) per mole of amine.

As particularly advantageous, especially for use in non-aqueous formulations according to the invention, the end-capped alkoxylated fatty amines and fatty alcohols have been found. The terminal hydroxy groups of the fatty alcohol alkoxylates and fatty amine alkoxylates are end-capped Fatty alcohol alkoxylates and fatty amine alkoxylates by -CC ₂₀ - alkyl groups, preferably methyl or ethyl groups, etherified.

In addition, as further nonionic surfactants and alkyl glycosides of the general formula RO (G) _X; For example, be used as compounds, especially with anionic surfactants, in which R is a primary straight-chain or methyl-branched, especially in the 2-position methyl-branched aliphatic radical having 8 to 22, preferably 12 to 18 carbon atoms and G is the symbol for a glycose unit with 5 or 6 C atoms, preferably for glucose. The degree of oligomerization x, which indicates the distribution of monoglycosides and oligoglycosides, is any number between 1 and 10; preferably x is 1.2 to 1.4.

Another class of preferred nonionic surfactants used either as the sole nonionic surfactant or in combination with other nonionic surfactants are alkoxylated, preferably ethoxylated or ethoxylated and propoxylated fatty acid alkyl esters, preferably having from 1 to 4 carbon atoms in the alkyl chain, especially fatty acid methyl esters as they are for example, in Japanese Patent Application JP 58/217598, or which are preferably prepared according to the method described in International Patent Application WO-A-90/13533.

Other suitable surfactants are so-called gemini surfactants. These are generally understood as meaning those compounds which have two hydrophilic groups and two hydrophobic groups per molecule. These groups are usually separated by a so-called "spacer". This spacer is usually a carbon chain that should be long enough for the hydrophilic groups to be spaced sufficiently apart for them to act independently of each other. Such surfactants are generally characterized by an unusually low critical micelle concentration and the ability to greatly reduce the surface tension of the water. In exceptional cases, however, the term gemini surfactants is understood to mean not only dimeric but also trimeric surfactants. Suitable gemini surfactants are, for example, sulfated hydroxy mixed ethers according to the German patent application DE-A-43 21 022 or dimer alcohol bis- and trimer alcohol tris sulfates and ether sulfates according to the international patent application WO-A-96/23768. End-capped dimeric and trimeric mixed ethers according to the German patent application DE-A-195 13 391 are distinguished in particular by their bi-and multifunctionality. Thus, said end-seal encapsulated surfactants have good wetting properties and are low foaming, so that they are particularly suitable for use in machine washing or cleaning processes.

However, it is also possible to use gemini-polyhydroxy fatty acid amides or poly-polyhydroxy-hydroxy fatty acid amides as described in international patent applications WO-A-95/199595, WO-A-95/19954 and WO-A-95/19955.

Further suitable surfactants are polyhydroxy fatty acid amides of the following formula

^RJ

R ⁴ -CO-N- [Z]

in which R is CO for an aliphatic acyl radical having 6 to 22 carbon atoms, R is hydrogen, an alkyl or hydroxyalkyl radical having 1 to 4 carbon atoms and [Z] is a linear or branched polyhydroxyalkyl radical having 3 to 10 carbon atoms and 3 to 10 hydroxyl groups. The polyhydroxy fatty acid amides are known substances which can usually be obtained by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride.

The group of polyhydroxy fatty acid amides also includes compounds of the following formula

R-O-R '

R ⁵ -CO-N- [Z] in the R ^{5 is} a linear or branched alkyl or alkenyl radical having 7 to 12 1 ohlenstoffatomen, R is a linear, branched or cyclic alkyl radical or an aryl radical having 2 to 8 carbon atoms and R ^{7 is} a linear, branched or cyclic alkyl radical or an aryl radical or an oxy-alkyl radical having 1 to 8 carbon atoms, where Cι- ₄ - alkyl or phenyl radicals are preferred and [Z] is a linear polyhydroxyalkyl radical whose alkyl chain is substituted with at least two Hydroxylgmppen, or alkoxylated, preferably ethoxylated or propoxylated derivatives of this residue. [Z] is preferably obtained by reductive amination of a reduced sugar, for example glucose, fructose, maltose, lactose, galactose, mannose or xylose. The N-alkoxy- or N-aryloxy-substituted compounds can then be converted into the desired polyhydroxy fatty acid amides according to the teaching of international patent application WO-A-95/07331, for example, by reaction with fatty acid methyl esters in the presence of an alkoxide as catalyst.

For the fabric care compositions according to the invention, it has proved to be advantageous if nonionic surfactants selected from the group of alkoxylated fatty alcohols and / or alkyl glycosides, in particular mixtures of alkoxylated fatty alcohols and alkyl glycosides, are used.

In the textile care agents according to the invention are in a preferred embodiment, nonionic surfactants in amounts of up to 35 wt .-%, preferably from 5 to 25 wt .-%, particularly preferably from 10 to 20 wt .-%, each based on the total agent ,

Furthermore, the textile care agents according to the invention may additionally or instead of the nonionic surfactants also contain anionic surfactants. Through the use of anionic surfactants, the soil release behavior of the compositions according to the invention is markedly increased during the washing process, without significantly impairing the effect of the cellulose ethers to be used according to the invention, despite their cationic charge, as a lint reduction component and anti-crease component. As anionic surfactants, for example, those of the sulfonate type and sulfates are used. Preferred surfactants of the sulfonate type are C 1 -C ₃ -alkylbenzenesulfonates, olefinsulfonates, ie mixtures of alkene and hydroxyalkanesulfonates and also disulfonates, such as are obtained, for example, from C ₂ . ₁₈ -Monoolefmen with terminal or internal double bond by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation obtained. Also suitable are alkanesulfonates, which are obtained from Cι ₂ -ι _8- alkanes, for example by sulfochlorination or sulfoxidation with subsequent hydrolysis or neutralization. Likewise, the esters of α-sulfo fatty acids (ester sulfonates), for example the α-sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids are also suitable.

Further suitable anionic surfactants are sulfated fatty acid glycerol esters. Fatty acid glycerol esters are the mono-, di- and triesters and mixtures thereof, as obtained in the preparation by esterification of a monoglycerol with 1 to 3 moles of fatty acid or in the transesterification of triglycerides with 0.3 to 2 moles of glycerol become. Preferred sulfated fatty acid glycerol esters are the sulfonation products of saturated fatty acids having 6 to 22 carbon atoms, for example caproic acid, caprylic acid, capric acid, myristic acid, lauric acid, palmitic acid, stearic acid or behenic acid.

Alk (en) ylsulfates are the alkali metal salts and, in particular, the sodium salts of the sulfuric acid half esters of the C ₂ -C ₈ -fatty alcohols, for example of coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or the C ₁ -C ₂₀ -oxo alcohols and those half-esters of secondary alcohols of these chain lengths are preferred. Also preferred are alk (en) ylsulfates of said chain length, which contain a synthetic, produced on a petrochemical basis straight-chain alkyl radical, which have an analogous degradation behavior as the adequate compounds based on oleochemical raw materials. From washing technical interest are the -C ₂ -Cι ₆ alkyl sulfates and -C ₂ -Cι ₅ alkyl sulfates and -C -C ₅ alkyl sulfates are preferred. In addition, 2,3-alkyl sulfates, which are produced for example according to patents US 3,234,258 or US 5,075,041 and can be obtained as commercial products from Shell Oil Company under the name DAN ^®, are suitable anionic surfactants. Also, the Schwefelsäuremonoester with 1 to 6 moles of ethylene ethoxylated straight-chain or branched C - ₂ ι-alcohols such as 2-methyl-branched C ₉ -n alcohols containing on average 3.5 mol ethylene oxide (EO) or Cι ₂ -ι ₈ 1 to 4 EO fatty alcohols, referred to as fatty alcohol ether sulfates, are suitable and particularly preferred anionic surfactants within the scope of this invention.

Further suitable anionic surfactants are also the salts of alkylsulfosuccinic acid, which are also referred to as sulfosuccinates or as sulfosuccinic acid esters and the monoesters and / or diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and in particular ethoxylated fatty alcohols. Preferred sulfosuccinates contain C ₈ _ι ₈ fatty alcohol radicals or mixtures of these. Particularly preferred sulfosuccinates contain a fatty alcohol residue derived from ethoxylated fatty alcohols, which by themselves are nonionic surfactants. Again, sulfosuccinates whose fatty alcohol radicals are derived from ethoxylated fatty alcohols with a narrow homolog distribution are particularly preferred. Likewise, it is also possible to use alk (en) ylsuccinic acid having preferably 8 to 18 carbon atoms in the alk (en) yl chain or salts thereof.

As further anionic surfactants are particularly soaps into consideration. Suitable examples are the saturated fatty acid soaps, such as the salts of lauric acid, myristic acid, palmitic acid, stearic acid, hydrogenated erucic acid and behenic acid and in particular from natural fatty acids, e.g. Coconut, palm kernel or tallow fatty acids, derived soap mixtures.

The anionic surfactants including the soaps may be in the form of their sodium, potassium or ammonium salts, as well as soluble salts of organic bases such as mono-, di-triethanolamine. The anionic surfactants are preferably present in the form of their sodium or potassium salts, in particular in the form of the sodium salts. For the nonaqueous liquid detergents according to the invention, however, the ammonium salts, in particular the salts of organic bases, such as, for example, isopropylamine, are preferred. Another class of anionic surfactants is the class of ether carboxylic acids obtainable by reaction of fatty alcohol ethoxylates with sodium chloroacetate in the presence of basic catalysts. They have the general formula: R ¹⁰ O- (CH ₂ -CH ₂ -O) _p -CH ₂ -COOH with R ¹⁰ = -CC] ₈ and p = 0.1 to 20. Ethercarboxylic acids are water hardness insensitive and have excellent surfactant properties on. Production and use are for example in soaps, oils, fats, waxes 101, 37 (1975); 115, 235 (1989) and surfactants Deterg. 25, 308 (1988).

In a preferred embodiment, the textile cleaners according to the invention contain anionic surfactants, preferably selected from the group of fatty alcohol sulfates and / or fatty alcohol ether sulfates and / or alkylbenzenesulfonates and / or soaps.

Depending on the intended use of the textile care agents according to the invention, the content of anionic surfactants can vary considerably. If the textile care agents are present as mild-wash or after-treatment agents, for example as fabric softeners, the amounts are normally below 10% by weight, preferably below 5% by weight and in particular below 1% by weight, based in each case on the entire composition ,

If the textile care agents are present as solid or liquid heavy-duty detergents, for example as nonaqueous liquid detergents, anionic surfactants may be used in amounts of up to 65% by weight, preferably in amounts of up to 50% by weight, more preferably in amounts of from 5 to 35% by weight. -%, in each case based on the total mean, be included.

Furthermore, the textile care agents according to the invention may additionally contain enzymes in a preferred embodiment.

Enzymes support the washing processes in a variety of ways, especially in the removal of poorly bleachable impurities, such as protein stains. The incorporation of enzymes in Waschmittelformuliemngen, especially in liquid fabric care products but often causes problems because it may lead to incompatibilities with other detergent ingredients, which in turn can cause a loss of activity of the enzymes. Surprisingly, it was found that through the use the copolymers to be used according to the invention the stability of the enzymes in wash liquor or textile care formulation, in particular in liquid fabric care formulations, can be improved.

Suitable enzymes are, in particular, those from the classes of the hydrolases, such as the proteases, esterases, lipases or lipolytic enzymes, amylases, cellulases or other glycosyl hydrolases and mixtures of the enzymes mentioned. All of these hydrolases in the wash contribute to the removal of stains such as proteinaceous, greasy or starchy stains and graying. In addition, cellulases and other glycosyl hydrolases may contribute to color retention and to enhancing the softness of the fabric by removing pilling and microfibrils. Oxireductases can also be used for bleaching or inhibiting color transfer. Particularly suitable are enzymatic active substances obtained from bacterial strains or fungi such as Bacillus subtilis, Bacillus licheniformis, Streptomyceus griseus and Humicola insolens. Preferably, subtilisin-type proteases and in particular proteases derived from Bacillus lentus are used. In this case, enzyme mixtures, for example from protease and amylase or protease and lipase or lipolytic enzymes or protease and cellulase or from cellulase and lipase or lipolytic enzymes or from protease, amylase and lipase or lipolytic enzymes or protease, lipase or lipolytic enzymes and cellulase, but in particular protease and / or lipase-containing mixtures or mixtures with lipolytic enzymes of particular interest. Examples of such lipolytic enzymes are the known cutinases. Peroxidases or oxidases have also proved suitable in some cases. Suitable amylases include in particular α-amylases, iso-amylases, pullulanases and pectinases. As cellulases are preferably cellobiohydrolases, endoglucanases and ß-glucosidases, which are also called cellobiases, or mixtures thereof used. Since different cellulase types differ by their CMCase and avicelase activities, the desired activities can be set by targeted mixtures of the cellulases. The enzymes may be adsorbed or coated on carriers to protect against premature degradation.

In a preferred embodiment, the textile care agents according to the invention contain enzymes, preferably selected from the group of proteases and / or amylases and / or cellulases.

If the textile care agents according to the invention are present as mild detergents or post-treatment agents, for example as fabric softeners, they can, in a preferred embodiment, comprise cellulase, preferably in an amount of from 0.005 to 2% by weight, particularly preferably from 0.01 to 1% by weight, in particular from 0.02 to 0.5 wt .-%, each based on the total agent included.

Preferred liquid fabric care agents in one preferred embodiment contain one or more nonaqueous, water-miscible solvents.

Solvents which can be used in the water-containing agents according to the invention are derived, for example, from the group of monohydric or polyhydric alcohols, alkanolamines or glycol ethers, provided they are miscible with water in the concentration range desired for use. The solvents are preferably selected from ethanol, n- or i-propanol, butanols, glycol, propane or butanediol, glycerol, diglycol, propyl- or butyldiglycol, hexylene glycol, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol propyl ether,

Some glycol ethers are available under the trade names Arcosolv ^® (Arco Chemical Co.) or Cellosolve ^®, carbitol ^® or Propasol ^® (Union Carbide Corp.); this includes for example ButylCarbitol® ^®, hexyl carbitol ^®, MethylCarbitol® ^®, and carbitol ^® itself, (2- (2-ethoxy) ethoxy) ethanol. The choice of glycol ether can be readily made by one skilled in the art on the basis of its volatility, water solubility, weight percent of the total agent, and the like. Pyrrolidone solvents, such as N-alkylpyrrolidones, for example N-methyl-2-pyrrolidone or NC ₈ -C ₂ -alkylpyrrolidone, or 2-pyrrolidone, can also be used. Further preferably, alcohols can be used. These include low molecular weight liquid polyethylene glycols, for example polyethylene glycols having a molecular weight of 200, 300, 400 or 600. Further suitable other alcohols are, for example, lower alcohols such as ethanol, propanol, isopropanol and n-butanol, C ₂ -C ₄ - Polyols, such as diols or triols, for example ethylene glycol, propylene glycol, glycerol or mixtures thereof.

The textile care agents according to the invention, if present in liquid form, in a preferred embodiment contain up to 95% by weight, particularly preferably 20 to 90% by weight and in particular 50 to 80% by weight of one or more solvents, preferably water-soluble Solvent and especially water.

In a preferred Ausführangsform of the invention, the fabric care agents additionally contain plasticizer components, preferably cationic surfactants. In particular, when the textile care agents according to the invention are present as mild or textile aftertreatment agents, for example as fabric softeners, the use of additional plasticizer components has proven to be extremely advantageous. In particular, when washing delicate textiles, such as silk, wool or linen, which are washed and ironed at low temperatures, the use of plasticizer components has proven itself. The plasticizer components facilitate, in addition to the In addition to using cellulose ethers to iron the textiles and reduce the static charge of the textile materials.

Examples of fabric softening components are quaternary ammonium compounds, cationic polymers and emulsifiers, such as those used in hair care products and also in textile saliva.

Suitable examples are quaternary ammonium compounds of the formulas (III) and (IV),

The agents according to the invention may contain builders. All builders conventionally used in detergents and cleaning agents can be incorporated into the compositions according to the invention, in particular zeolites, silicates, carbonates, organic cobuilders and, if there are no ecological prejudices against their use, also the phosphates.

Suitable crystalline, layered Νatriumsilikate have the general formula ΝaMSi _x O _{2x +} ι • y H ₂ O, wherein M is sodium or hydrogen, x is a number of 1.9 to 4 and y is a number from 0 to 20 and preferred values for x are 2, 3 or 4. Such crystalline sheet silicates are described, for example, in European Patent Application EP-A-0 164 514. Preferred crystalline layered silicates of the formula given are those in which M is sodium and x assumes the values 2 or 3. Particularly Both .beta.- and δ-sodium disilicates Na ₂ Si ₂ O ₅ • y H ₂ O are preferred, with beta-sodium disilicate, for example, obtained by the method / described in the international patent application WO-A-91 08,171th

The dissolution delay compared to conventional amorphous sodium silicates may have been caused in various ways, for example by surface treatment, compounding, compaction / compaction or by overdrying. In the context of this invention, the term "amorphous" is also understood to mean "X-ray amorphous". This means that the silicates do not yield sharp X-ray reflections typical of crystalline substances in X-ray diffraction experiments, but at most one or more maxima of the scattered X-rays having a width of several degrees of diffraction angle. However, it can very well lead to particularly good building properties if the silicate particles provide washed-out or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline regions of size 10 to a few hundred nm, values of up to max. 50 nm and in particular up to max. 20 nm are preferred. Such so-called X-ray amorphous silicates, which likewise have a dissolution delay compared with the conventional water glasses, are described, for example, in German patent application DE-A-44 00 024. Particularly preferred are compacted / compacted amorphous silicates, compounded amorphous silicates and overdried X-ray amorphous silicates.

Suitable zeolites have an average particle size of less than 10 μm (volume distribution, measuring method: Coulter Counter) and preferably contain 18 to 22% by weight, in particular 20 to 22% by weight, of bound water. The zeolites can also be used as overdried zeolites with lower water contents and then, due to their hygroscopicity, are suitable for removing unwanted residual traces of free water.

Other suitable builders are polymeric polycarboxylates, for example the alkali metal salts of polyacrylic acid or of polymethacrylic acid, for example those having a relative molecular weight of 500 to 70,000 g / mol.

The molecular weights stated here for polymeric polycarboxylates are weight-average molar masses M _{w of} the particular acid form which can in principle be determined by means of gel permeation chromatography (GPC), a UV detector being used. The measurement is carried out against an external standard, for example against a polyacrylic acid standard, which provides realistic molecular weight values due to its structural relationship with the polymers investigated. This information often differs significantly from the molecular weight data in which polystyrene sulfonic acids are used as standard. The molar masses measured against polystyrenesulfonic acids are generally much higher. Suitable polymers are in particular polyacrylates, which preferably have a molecular weight of 2,000 to 20,000 g / mol.

Copolymers of acrylic acid with maleic acid which contain 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid have proven to be particularly suitable. Their relative molecular weight, based on free acids, is generally from 2,000 to 70,000 g / mol, preferably from 20,000 to 50,000 g / mol and in particular from 30,000 to 40,000 g / mol. The (co) polymeric polycarboxylates can be used either as an aqueous solution or, preferably, as a powder.

The oxidized derivatives of such dextrins are their reaction products with oxidizing agents which are capable of oxidizing at least one alcohol function of the saccharide ring to the carboxylic acid function. Such oxidized dextrins and processes for their preparation are known, for example, from European Patent Applications EP-A-0 232 202, EP-A-0 427 349, EP-A-0 472 042 and EP-A-0 542496 and International Patent Applications WO-A No. 92/18542, WO-A-93/08251, WO-A-93/16110, WO-A-94/28030, WO-A-95/07303, WO-A-95/12619 and WO-A-95 / 20608 known.

The compositions according to the invention may contain additional anti-wrinkling agents to support the corresponding action of the cellulose ether to be used, since textile fabrics, in particular of rayon, wool, cotton and their mixtures, may tend to wrinkle, because the individual fibers are resistant to bending, buckling, pressing and crushing transversely to the Fiber direction are sensitive. These include, for example, synthetic products based on fatty acids, Fatty acid esters, fatty acid amides, -alkylolestem, -alkylolamiden or fatty alcohols, which are usually reacted with ethylene oxide, or products based on lecithin or modified phosphoric acid ester.

The agents according to the invention may contain grayness inhibitors. These have the task to keep suspended from the fiber debris suspended in the fleet and so prevent the re-raising of the dirt. Water-soluble colloids of mostly organic nature are suitable for this purpose, for example glue, gelatine, salts of ether sulfonates of starch or of cellulose or salts of acidic sulfuric acid esters of cellulose or starch. Also, water-soluble, acid Grappen containing polyamides are suitable for this purpose. Furthermore, soluble starch preparations and other than the above-mentioned starch products can be used, e.g. degraded starch, aldehyde levels, etc. Also polyvinylpyrrolidone is useful. However, preference is given to anionic or nonionic cellulose ethers such as carboxymethylcellulose (Na salt), methylcellulose, hydroxyalkylcellulose and mixed ethers such as methylhydroxyethylcellulose, methylhydroxypropylcellulose and / or methylcarboxymethylcellulose.

In a particularly preferred embodiment, the textile care agents according to the invention, preferably liquid detergents, are present as a portion in a completely or partially water-soluble coating. Portioning makes it easier for the consumer to dose.

The textile care agents can be packed in foil bags, for example. Pouches made of water-soluble film make it unnecessary for the consumer to tear open the packaging. In this way, convenient dosing of a single portion sized for a wash is by inserting the pouch directly into the washing machine or by throwing the pouch into a certain amount of water, for example in a bucket, bowl or hand basin. possible. The film bag surrounding the washing portion dissolves without residue when it reaches a certain temperature. Detergents packaged in bags of water-soluble film are described in large numbers in the prior art. So revealed the German patent application DE 198 31 703 a portioned detergent or cleaner preparation in a bag of water-soluble film, in particular in a bag of (optionally acetalized) polyvinyl alcohol (PVAL), wherein at least 70 wt .-% of the particles of detergent or cleaning agent Preparation particle sizes> 800 microns have.

Numerous processes for the preparation of water-soluble detergent portions, which are basically also useful in the context of the present invention, already exist in the prior art. The best known methods are the tubular film processes with horizontal and vertical sealing seams. Also suitable for the production of film bags or dimensionally stable detergent portions is the thermoforming process (deep drawing process), as described for example in WO-Al 00/55068. However, the water-soluble envelopes need not necessarily consist of a film material, but can also represent dimensionally stable containers that can be obtained for example by means of an injection molding process. A known process for producing water-soluble injection molded hollow bodies containing detergents and / or cleaning agents is described, for example, in WO-Al 01/36290.

Furthermore, processes for the preparation of water-soluble capsules of polyvinyl alcohol or gelatin are known in the prior art, which in principle offer the possibility to provide capsules with a high degree of filling. The methods are based on introducing the water-soluble polymer into a shaping cavity. The filling and sealing of the capsules takes place either synchronously or in successive steps, in which case the filling of the capsules takes place through a small opening in the latter case. Processes in which the filling and sealing run in parallel are described, for example, in WO 97/35537. The filling of the capsules is carried out by a Befüllkeil, which is above two mutually rotating drums, which have ball half shells on its surface, is arranged. The drums carry polymer bands that cover the ball half-shell cavities. At the positions where the polymer band of one drum coincides with the polymer tape of the opposite drum, a seal takes place. In parallel, the filling material is injected into the forming capsule, the Injektionsdmck the BefüUflüssigkeit the polymer tapes pressed into the Kugelhalbschalenkavitäten. A process for the preparation of water-soluble capsules, in which first the filling and then the sealing takes place, is disclosed in WO 01/64421. The manufacturing process is based on the so-called Bottle-Pack ^® method, as described for example in German Offenlegungsschrift DE 14 114 69. In this case, a tubular preform is guided into a two-part cavity. The cavity is closed, the lower tube portion is sealed, then the tube is inflated to form the capsule shape in the cavity, filled and finally sealed.

The shell material used for the preparation of the water-soluble portion is preferably a water-soluble polymeric thermoplastic, more preferably selected from the group (optionally partially acetalized) polyvinyl alcohol, polyvinyl alcohol copolymers, polyvinylpyrrolidone, polyethylene oxide, gelatin, cellulose and derivatives thereof, starch and derivatives thereof, blends and ^" composites, inorganic salts and mixtures of said materials, preferably Hydroxypropylrnethylcellulose and / or polyvinyl alcohol blends.

In one embodiment of the invention, the wrapping material may consist entirely or partially of the cellulose ethers to be used according to the invention in the textile care agent.

The polyvinyl alcohols described above are commercially available, for example under the trade name Mowiol ^® (Clariant). In the present invention, particularly suitable polyvinyl alcohols are, for example, Mowiol ^® 3-83, Mowiol ^® 4-88, Mowiol ^® 5-88, Mowiol ^® 8-88 and Clariant L648.

Another object of the invention is the use of a cellulose ether to be used according to the invention in a textile care agent for ironing relief of textile fabrics.

Surprisingly, it has also been found that the cellulose ethers to be used according to the invention not only reduce crease formation and ensure a smooth textile surface, but also significantly improve the soft feel of the treated textiles.

Another object of the invention is therefore the use of a cellulose ether to be used according to the invention in a textile care product for crease reduction, smoothing and improving the soft feel of textile fabrics.

Another object of the invention is a Konditioniersubstrat, which is a substrate which is impregnated with the fabric care agent according to the invention and / or impregnated.

The substrate material is made of porous materials capable of reversibly feeding and dispensing an impregnating liquid. In question come for it both three-dimensional structures, such as sponges, but preferably porous, sheet-like cloths. They may consist of a fibrous or cellular flexible material which has sufficient thermal stability for use in the dryer and which can retain sufficient amounts of impregnating or coating agent to effectively condition fabrics without significant bleeding or bleeding of the composition during storage he follows. These wipes include cloths of woven and non-woven synthetic and natural fibers, felt, paper or foam, such as hydrophilic polyurethane foam.

Preferably, conventional cloths of nonwoven material (nonwovens) are used here. Nonwovens are generally defined as adhesively bonded fibrous products having a mat or layered fibrous structure, or those comprising fibrous mats in which the fibers are randomly or randomly distributed. The fibers may be of natural origin, such as wool, silk, jute, hemp, cotton, linen, sisal or ramie; or synthetically produced, such as rayon, Cellulose esters, polyvinyl derivatives, polyolefins, polyamides, viscose or polyester. In general, any fiber diameter or titer is suitable for the present invention. Preferred conditioning substrates according to the invention consist of a nonwoven material which contains cellulose. The nonwoven fabrics employed herein tend not to rupture or disintegrate due to the random or random arrangement of fibers in the nonwoven material which impart excellent strength in all directions when used, for example, in a domestic tumble dryer. Examples of nonwoven fabrics suitable as substrates in the present invention are known, for example, from WO 93/23603. Preferred porous and flat conditioning cloths consist of one or different fiber materials, in particular of cotton, refined cotton, polyamide, polyester or mixtures of these. The conditioning substrates in fabric form preferably have a 9 9

Another object of the invention is a conditioning method for conditioning wet textiles by means of the conditioning substrate according to the invention.

The conditioning process is carried out by using the conditioning substrate according to the invention together with moist textiles, for example obtained from a previous washing process, in a textile drying process. The textile drying process usually takes place in a device for drying textiles, preferably in a household laundry drier.

Further objects of the invention are methods for reducing linting, reducing pilling, ironing, creasing, smoothing and / or improving the soft feel of textile fabrics by contacting textile sheets with a fabric care composition according to the invention and / or a conditioning substrate according to the invention in a textile cleaning process and / or textile drying process.

The textile care agents according to the invention can be added in their conditioning aspect directly with the wet laundry in a household dryer and / or a washing machine.

The textile care compositions according to the invention can be prepared by simple mixing and stirring of the individual components familiar to the person skilled in the art. The cellulose ethers to be used according to the invention can be admixed as a solution or slurry, preferably in aqueous form, to a particular liquid agent and / or can be compounded or granulated, mixed or tableted or pelletized as a dried powder, preferably as a carrier on a detergent component.

Examples

Example 1: Composition

Table 1 shows the liquid formulation according to the invention M1 and the comparative formulation VI. All information is given in weight percent, in each case based on the total mean.

Table 1

^w Hydroxyethyl cellulose reacted with diethylaminoethylene chloride

The test textiles indicated in Table 2 below were washed with 120 g of the respective composition [water hardness: 16 ° dH] (Miele W308, standard program 40 ° C.) and then dried (hanging for 2 days on a line in a climatic chamber at 20 ° C.) 65% humidity).

The washing and drying cycles were repeated 9 times each (ie a total of 10 wash / dry cycles). The textile to be tested was stretched in a dynamometer (Hounsfield H5KS) for 1 minute by 8.0% of the original length, then relaxed for 3 minutes and then measured the remaining residual strain. Table 2 below shows the residual elongation of the non-washed textile (U) and the residual elongation determined by the use of the agent M1 or VI.
