Description

The present invention relates to detergents or cleaners containing polycarbonate, polyurethane and / or polyurea polyorganosiloxane compounds as color transfer inhibiting agents in the washing and / or cleaning of textiles.

Detergents and cleaners in addition to the indispensable for the washing and cleaning process ingredients such as surfactants and builders usually other ingredients that can be summarized under the term washing aids and the so different drug groups include foam regulators, graying inhibitors, bleach, bleach activators and enzymes. Such auxiliaries also include substances which are intended to prevent dyed textile fabrics from causing a changed color impression after washing. This color impression change washed, i. cleaner, textiles can be based on the fact that dye components are removed by the Waschbeziehungsweise cleaning process from the textile ("fading"), on the other hand, from other colored textiles detached dyes on the textile precipitate ("discoloration"). The discoloration aspect may also play a role in undyed laundry items when washed together with colored laundry items. In order to avoid these unwanted side effects of removing dirt from textiles by treatment with usually surfactant-containing aqueous systems, detergents, especially if they are provided as so-called color or colored laundry detergents for colored textiles, contain active ingredients that prevent the detachment of dyes from the textile or At least the deposition of detached, located in the wash liquor to avoid dyes on textiles. However, many of the commonly used polymers have such a high affinity for dyes that they draw more of them from the dyed fiber, resulting in loss of color when used.

From the patent US 5 534 182 A are color transfer inhibiting detergent compositions comprising 0.1 to 20 wt .-% polyethoxylated urethane or acrylamide polymer having a molecular weight of about 2000 to 50,000 as a color transfer inhibitor and 99.9 to 80 wt .-% additive (water, solvent, builder, surfactant, Fabric softener).

Surprisingly, it has now been found that certain polycarbonate, polyurethane and / or polyurea polyorganosiloxane compounds lead to unexpectedly high color transfer inhibition when used in detergents. Particularly pronounced is the prevention of dyeing of white or other colored fabrics by washed out of textiles dyes. It is conceivable that the below defined in more detail Apply compounds during washing on the textiles and thereby on the one hand effectively prevent a detachment of the dyes from the textiles and on the other hand repellent effect on already in the fleet located dye molecules.

The term acid addition compound means a salt-like compound which can be obtained by protonation of basic groups in the molecule, such as in particular the optionally present amino groups, for example by reaction with inorganic or organic acids. The acid addition compounds may be used as such or may optionally form under conditions of use of the compounds defined above. If the polycarbonate, polyurethane and / or polyurea-polyorganosiloxane compound contains moieties - (N ⁺ R ² R ³ ) -, common counter anion ions, such as halide, hydroxide, sulfate, carbonate, are present in order to ensure charge neutrality.

When in the polycarbonate, polyurethane and / or polyurea-polyorganosiloxane compounds present polyorganosiloxane structural element is preferably the structure - (SiR ⁴ ₂ O) _p - (SiR ⁴ ₂₎ -, wherein R ⁴ is a straight chain, cyclical or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 20 carbon atoms, and p = 1 to 999.

The mentioned active ingredients contribute to both previously mentioned aspects of color constancy, that is to say they reduce both discoloration and fading, although the effect of preventing staining, especially when washing white textiles, is most pronounced. Further disclosed is therefore the use of a corresponding active ingredient to avoid the change in the color impression of textiles in their washing in particular surfactant-containing aqueous solutions. By changing the color impression is by no means the difference between dirty and clean textile to understand, but the color difference between each clean textile before and after the washing process.

Another object of the invention is a process for washing dyed textiles in surfactant-containing aqueous solutions, which is characterized in that one uses a surfactant-containing aqueous solution containing an active ingredient as defined above. In such a method, it is possible to wash white or undyed textiles together with the dyed textile without the white or undyed textile being dyed.

However, it is also possible to use enzymatic systems comprising a peroxidase and hydrogen peroxide or a substance which produces hydrogen peroxide in water. The addition of a mediator compound for the peroxidase, for example an acetosyringone, a phenol derivative or a phenotiazine or phenoxazine, is preferred in this case, whereby also above-mentioned polymeric Farbübertragungsinhibitorwirkstoffe can be used. Polyvinylpyrrolidone preferably has an average molecular weight in the range from 10 000 to 60 000, in particular in the range from 25 000 to 50 000, for use in compositions according to the invention. Among the copolymers, those of vinylpyrrolidone and vinylimidazole in a molar ratio of 5: 1 to 1: 1 having an average molecular weight in the range of 5,000 to 50,000, especially 10,000 to 20,000 are preferred.

The detergents according to the invention, which may be in the form of homogeneous solutions or suspensions, especially in powdered solids, in densified particle form, may in principle contain, in addition to the active ingredient used in accordance with the invention, all known ingredients customary in such agents. The agents according to the invention may in particular be builders, surface-active surfactants, bleaches based on organic and / or inorganic peroxygen compounds, bleach activators, water-miscible organic solvents, enzymes, sequestering agents, electrolytes, pH regulators and other auxiliaries, such as optical brighteners, grayness inhibitors, foam regulators and colorants Contain fragrances.

Suitable nonionic surfactants are in particular alkyl glycosides and ethoxylation and / or propoxylation of alkyl glycosides or linear or branched alcohols each having 12 to 18 carbon atoms in the alkyl moiety and 3 to 20, preferably 4 to 10 alkyl ether groups. Furthermore, corresponding ethoxylation and / or propoxylation of N-alkyl-amines, vicinal diols, fatty acid esters and fatty acid amides, which correspond to said long-chain alcohol derivatives with respect to the alkyl part, as well as of alkylphenols having 5 to 12 carbon atoms in the alkyl radical.

Vorzugsweise leiten sich die Polyhydroxyfettsäureamide von reduzierenden Zuckern mit 5 oder 6 Kohlenstoffatomen, insbesondere von der Glucose ab. Zur Gruppe der Polyhydroxyfettsäureamide gehören auch Verbindungen der Formel (VII),

in der R³ für einen linearen oder verzweigten Alkyl- oder Alkenylrest mit 7 bis 12 Kohlenstoffatomen, R⁴ für einen linearen, verzweigten oder cyclischen Alkylenrest oder einen Arylenrest mit 2 bis 8 Kohlenstoffatomen und R⁵ für einen linearen, verzweigten oder cyclischen Alkylrest oder einen Arylrest oder einen Oxy-Alkylrest mit 1 bis 8 Kohlenstoffatomen steht, wobei C₁-C₄-Alkyl- oder Phenylreste bevorzugt sind, und [Z] für einen linearen Polyhydroxyalkylrest, dessen Alkylkette mit mindestens zwei Hydroxylgruppen substituiert ist, oder alkoxylierte, vorzugsweise ethoxylierte oder propoxylierte Derivate dieses Restes steht. [Z] wird auch hier vorzugsweise durch reduktive Aminierung eines Zuckers wie Glucose, Fructose, Maltose, Lactose, Galactose, Mannose oder Xylose erhalten. Die N-Alkoxy- oder N-Aryloxy-substituierten Verbindungen können dann beispielsweise durch Umsetzung mit Fettsäuremethylestern in Gegenwart eines Alkoxids als Katalysator in die gewünschten Polyhydroxyfettsäureamide überführt werden. Eine weitere Klasse bevorzugt eingesetzter nichtionischer Tenside, die entweder als alleiniges nichtionisches Tensid oder in Kombination mit anderen nichtionischen Tensiden, insbesondere zusammen mit alkoxylierten Fettalkoholen und/oder Alkylglykosiden, eingesetzt werden, sind alkoxylierte, vorzugsweise ethoxylierte oder ethoxylierte und propoxylierte Fettsäurealkylester, vorzugsweise mit 1 bis 4 Kohlenstoffatomen in der Alkylkette, insbesondere Fettsäuremethylester. Auch nichtionische Tenside vom Typ der Aminoxide, beispielsweise N-Kokosalkyl-N,N-dimethylaminoxid und N-Talgalkyl-N,N-dihydroxyethylaminoxid, und der Fettsäurealkanolamide können geeignet sein. Die Menge dieser nichtionischen Tenside beträgt vorzugsweise nicht mehr als die der ethoxylierten Fettalkohole, insbesondere nicht mehr als die Hälfte davon. Als weitere Tenside kommen sogenannte Gemini-Tenside in Betracht. Hierunter werden im Allgemeinen solche Verbindungen verstanden, die zwei hydrophile Gruppen pro Molekül besitzen. Diese Gruppen sind in der Regel durch einen sogenannten "Spacer" voneinander getrennt. Dieser Spacer ist in der Regel eine Kohlenstoffkette, die lang genug sein sollte, dass die hydrophilen Gruppen einen ausreichenden Abstand haben, damit sie unabhängig voneinander agieren können. Derartige Tenside zeichnen sich im Allgemeinen durch eine ungewöhnlich geringe kritische Micellkonzentration und die Fähigkeit, die Oberflächenspannung des Wassers stark zu reduzieren, aus. In Ausnahmefällen werden unter dem Ausdruck Gemini-Tenside nicht nur derartig "dimere", sondern auch entsprechend "trimere" Tenside verstanden. Geeignete Gemini-Tenside sind beispielsweise sulfatierte Hydroxymischether oder Dimeralkohol-bis- und Trimeralkohol-tris-sulfate und -ethersulfate. Endgruppenverschlossene dimere und trimere Mischether zeichnen sich insbesondere durch ihre Bi- und Multifunktionalität aus. So besitzen die genannten endgruppenverschlossenen Tenside gute Netzeigenschaften und sind dabei schaumarm, so dass sie sich insbesondere für den Einsatz in maschinellen Wasch- oder Reinigungsverfahren eignen. Eingesetzt werden können aber auch Gemini-Polyhydroxyfettsäureamide oder Poly-Polyhydroxyfettsäureamide. Geeignet sind auch die Schwefelsäuremonoester der mit 1 bis 6 Mol Ethylenoxid ethoxylierten geradkettigen oder verzweigten C₇-C₂₁-Alkohole, wie 2-Methylverzweigte C₉-C₁₁-Alkohole mit im Durchschnitt 3,5 Mol Ethylenoxid (EO) oder C₁₂-C₁₈-Fettalkohole mit 1 bis 4 EO. Zu den bevorzugten Aniontensiden gehören auch die Salze der Alkylsulfobernsteinsäure, die auch als Sulfosuccinate oder als Sulfobernsteinsäureester bezeichnet werden, und die Monoester und/oder Diester der Sulfobernsteinsäure mit Alkoholen, vorzugsweise Fettalkoholen und insbesondere ethoxylierten Fettalkoholen darstellen. Bevorzugte Sulfosuccinate enthalten C₈- bis C₁₈-Fettalkoholreste oder Mischungen aus diesen. Insbesondere bevorzugte Sulfosuccinate enthalten einen Fettalkoholrest, der sich von ethoxylierten Fettalkoholen ableitet, die für sich betrachtet nichtionische Tenside darstellen. Dabei sind wiederum Sulfosuccinate, deren Fettalkohol-Reste sich von ethoxylierten Fettalkoholen mit eingeengter Homologenverteilung ableiten, besonders bevorzugt. Ebenso ist es auch möglich, Alk(en)ylbernsteinsäure mit vorzugsweise 8 bis 18 Kohlenstoffatomen in der Alk(en)ylkette oder deren Salze einzusetzen. Als weitere anionische Tenside kommen Fettsäure-Derivate von Aminosäuren, beispielsweise von N-Methyltaurin (Tauride) und/oder von N-Methylglycin (Sarkoside) in Betracht. Insbesondere bevorzugt sind dabei die Sarkoside beziehungsweise die Sarkosinate und hier vor allem Sarkosinate von höheren und gegebenenfalls einfach oder mehrfach ungesättigten Fettsäuren wie Oleylsarkosinat. Als weitere anionische Tenside kommen insbesondere Seifen in Betracht. Geeignet sind insbesondere gesättigte Fettsäureseifen, wie die Salze der Laurinsäure, Myristinsäure, Palmitinsäure, Stearinsäure, hydrierten Erucasäure und Behensäure sowie insbesondere aus natürlichen Fettsäuren, zum Beispiel Kokos-, Palmkern- oder Talgfettsäuren, abgeleitete Seifengemische. Zusammen mit diesen Seifen oder als Ersatzmittel für Seifen können auch die bekannten Alkenylbernsteinsäuresalze eingesetzt werden.The nonionic surfactants used are preferably alkoxylated, advantageously ethoxylated, in particular primary, alcohols having preferably 8 to 18 carbon atoms and on average 1 to 12 moles of ethylene oxide (EO) per mole of alcohol, in which the alcohol radical can be linear or preferably methyl-branched in the 2-position or may 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, C ₁₂ -C ₁₄ -alcohols with 3 EO or 4 EO, C ₉ -C ₁₁ -alcohols with 7 EO, C ₁₃ -C ₁₅ -alcohols with 3 EO, 5 EO, 7 EO or 8 EO, C ₁₂ -C ₁₈ -alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of C ₁₂ -C ₁₄ -alcohol with 3 EO and C ₁₂ -C ₁₈ -alcohol with 7 EO. The degrees of ethoxylation given represent statistical means which, for a particular product, may be an integer or a fractional number. Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE). In addition to these nonionic surfactants, fatty alcohols with more than 12 EO can also be used. Examples include (tallow) fatty alcohols with 14 EO, 16 EO, 20 EO, 25 EO, 30 EO or 40 EO. In particular, agents for use in mechanical processes usually extremely low-foam compounds are used. These include preferably C ₁₂ -C ₁₈ -Alkylpolyethylenglykolpolypropylenglykolether each with at 8 mol ethylene oxide and propylene oxide in the molecule. However, it is also possible to use other known low-foam nonionic surfactants, such as, for example, C ₁₂ -C ₁₈ -alkyl polyethylene glycol-polybutylene glycol ethers having in each case up to 8 mol of ethylene oxide and butylene oxide units in the molecule and end-capped alkylpolyalkylene glycol mixed ethers. Also particularly preferred are the hydroxyl-containing alkoxylated alcohols, as described in the European patent application EP 0 300 305 are described, so-called Hydroxymischether. The nonionic surfactants also include alkyl glycosides of the general formula RO (G) _x in which R is a primary straight-chain or methyl-branched, in particular 2-methyl-branched aliphatic radical having 8 to 22, preferably 12 to 18 carbon atoms and G represents a glycose unit having 5 or 6 C atoms, preferably glucose. The degree of oligomerization x, which indicates the distribution of monoglycosides and oligoglycosides, is any number - the size to be determined analytically as well can take broken values - between 1 and 10; preferably x is 1.2 to 1.4. Also suitable are polyhydroxy fatty acid amides of the formula (VI) in which R ¹ CO is an aliphatic acyl radical having 6 to 22 carbon atoms, R ^{2 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 preferably derived from reducing sugars having 5 or 6 carbon atoms, in particular from glucose. The group of polyhydroxy fatty acid amides also includes compounds of the formula (VII)

in the R ^{3 is} a linear or branched alkyl or alkenyl radical having 7 to 12 carbon atoms, R ^{4 is} a linear, branched or cyclic alkylene radical or an arylene radical having 2 to 8 carbon atoms and R ^{5 is} a linear, branched or cyclic alkyl radical or a Aryl radical or an oxy-alkyl radical having 1 to 8 carbon atoms, wherein C ₁ -C ₄ alkyl or phenyl radicals are preferred, and [Z] is a linear polyhydroxyalkyl radical whose alkyl chain is substituted with at least two hydroxyl groups, or alkoxylated, preferably ethoxylated or propoxylated derivatives of this group. [Z] is also obtained here preferably by reductive amination of a sugar such as 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, for example by reaction with fatty acid methyl esters in the presence of an alkoxide as catalyst. Another class of preferred nonionic surfactants used either as the sole nonionic surfactant or in combination with other nonionic surfactants, in particular together with alkoxylated fatty alcohols and / or alkyl glycosides, are alkoxylated, preferably ethoxylated or ethoxylated and propoxylated fatty acid alkyl esters, preferably from 1 to 4 carbon atoms in the alkyl chain, especially fatty acid methyl ester. Nonionic surfactants of the amine oxide type, for example N-cocoalkyl-N, N-dimethylamine oxide and N-tallowalkyl-N, N-dihydroxyethylamine oxide, and the fatty acid alkanolamides may also be suitable. The amount of these nonionic surfactants is preferably not more than that of the ethoxylated fatty alcohols, especially not more than half thereof. Other suitable surfactants are so-called gemini surfactants. These are generally those Understood compounds having two hydrophilic groups per molecule. These groups are usually separated by a so-called "spacer". This spacer is typically 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, the term gemini surfactants not only such "dimer", but also corresponding to "trimeric" surfactants understood. Suitable gemini surfactants are, for example, sulfated hydroxy mixed ethers or dimer alcohol bis and trimer alcohol tris sulfates and ether sulfates. End-capped dimeric and trimeric mixed ethers are characterized in particular by their bi- and multi-functionality. Thus, the end-capped surfactants mentioned 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 fatty acid amides. Also suitable are the sulfuric acid monoesters of straight-chain or branched C ₇ -C ₂₁ -alcohols ethoxylated with from 1 to 6 mol of ethylene oxide, such as 2-methyl-branched C ₉ -C ₁₁ -alcohols having on average 3.5 mol of ethylene oxide (EO) or C ₁₂ - C ₁₈ -fatty alcohols with 1 to 4 EO. The preferred anionic surfactants also include 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 to C ₁₈ fatty alcohol residues or mixtures of these. Particularly preferred sulfosuccinates contain a fatty alcohol residue derived from ethoxylated fatty alcohols, which by themselves are nonionic surfactants. Sulfosuccinates, whose fatty alcohol residues are derived from ethoxylated fatty alcohols with a narrow homolog distribution, are again 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. Suitable further anionic surfactants are fatty acid derivatives of amino acids, for example N-methyltaurine (Tauride) and / or N-methylglycine (sarcosides). Particularly preferred are the sarcosides or the sarcosinates and here especially sarcosinates of higher and optionally monounsaturated or polyunsaturated fatty acids such as oleyl sarcosinate. As further anionic surfactants are particularly soaps into consideration. Particularly suitable are 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, soap mixtures derived from natural fatty acids, for example coconut, palm kernel or tallow fatty acids. Together with these soaps or as a substitute for soaps, it is also possible to use the known alkenylsuccinic acid salts.

The anionic surfactants, including soaps, may be in the form of their sodium, potassium or ammonium salts and as soluble salts of organic bases, such as mono-, di- or 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.

Surfactants are present in detergents according to the invention in proportions of preferably from 5% by weight to 50% by weight, in particular from 8% by weight to 30% by weight.

An agent according to the invention preferably contains at least one water-soluble and / or water-insoluble, organic and / or inorganic builder. The water-soluble organic builder substances include polycarboxylic acids, in particular citric acid and sugar acids, monomeric and polymeric aminopolycarboxylic acids, in particular methylglycinediacetic acid, nitrilotriacetic acid and ethylenediaminetetraacetic acid and polyaspartic acid, polyphosphonic acids, in particular aminotris (methylenephosphonic acid), ethylenediaminetetrakis (methylenephosphonic acid) and 1-hydroxyethane-1,1-diphosphonic acid, polymeric hydroxy compounds such as dextrin and also polymeric (poly) carboxylic acids, in particular the polycarboxylates obtainable by oxidation of polysaccharides or dextrins, polymeric acrylic acids, methacrylic acids, maleic acids and copolymers thereof, which may also contain polymerized small amounts of polymerizable substances without carboxylic acid functionality. The molecular weight of the homopolymers of unsaturated carboxylic acids is generally between 3,000 and 200,000, of the copolymers between 2,000 and 200,000, preferably 30,000 to 120,000, each based on the free acid. A particularly preferred acrylic acid-maleic acid copolymer has a molecular weight of from 30,000 to 100,000. Commercially available products are, for example, Sokalan® CP 5, CP 10 and PA 30 from BASF. Suitable, although less preferred, compounds of this class are copolymers of acrylic or methacrylic acid with vinyl ethers, such as vinylmethyl ethers, vinyl esters, ethylene, propylene and styrene, in which the acid content is at least 50% by weight.

Examples Example 1: Color transfer inhibition

The following table shows the compositions of a washing or cleaning agent E1 according to the invention and those of a comparative example V1: Table 1: V1 E1 C _12-18 fatty alcohol with 7 EO 10 10 C _12-14 alkylpolyglycoside 3 3 Polyacrylate thickener 0.2 0.2 ethanol 3 3 citric acid 5 5 phosphonic 0.4 0.4 active substance - 0.4 PVP / PVI 0.1 - Caustic soda (50%) 3.2 3.2 propylene glycol 9 9 boric acid 1 1 Silicone antifoam 0,003 0,003 Perfume 1.5 1.5 Enzymes *, dye + + water Ad 100 Ad 100 * Mixture of cellulase, amylase and protease

All detergent or cleaning compositions were stable and showed no precipitates.

To determine the color transfer inhibiting properties of the individual detergents or cleaning agents, a staining scale rating (SSR), which is based on ISO 105A04, was performed. For this purpose, two white fabrics (so-called accompanying fabric) were washed with a colored fabric using in each case one of the abovementioned detergent or cleaner compositions in a Lini tester (ex Atlas) at 60 ° C, then rinsed with water and dried hanging at room temperature. Subsequently, the degree of discoloration of the two accompanying tissues was determined spectrophotometrically.

The degree of discoloration was then given in values from 1 (strong discoloration) to 5 (no discoloration).

It became clear from the SSR that the composition according to the invention has better dye-transfer-inhibiting properties with respect to several textile dyes than the comparison formulation.

Example 2: color retention

The agents mentioned in Example 1 were tested on the dyed testicles under conditions otherwise similar to Example 1:

Washing conditions:

• Cooking / color washing program, 60 ° C / Miele W 985
• Number of wash / dry cycles: 5
• Water hardness: 16 ° dH
• Dosage: 75g

Test textiles:

• Dyed textiles:
• Red textile
• Yellow textile
• Black textile

Measurement and evaluation of the results:

The color changes of the textiles are measured with a Spectraflash device (with UV without luster) and the dL, da, db, dE values are converted into GSC values; Scale 1 - 5 (1 = bad, 5 = no change)

The use of the agent E1 according to the invention, when comparing the averages of all five test textiles, resulted in a number that is at least 1 value higher than the use of the agent V1.
