Definitions
- the present invention relates to aqueous dispersions which contain fatty substances and emulsifiers as fabric softeners, which are characterized by a high positive zeta potential of the dispersion.
- Textile treatment agents that have a softening effect on laundry are well known. you will be usually used in the last rinse of a machine wash and give the laundry a pleasant, soft feel, as they have a pronounced sorption capacity on a wide variety of fiber surfaces.
- the coating of the fiber with the long-chain molecules leads to a sliding effect between the fibers and prevents the water or dry rigidity that is responsible for the hard grip of the fabric.
- the adsorption mechanism for the drawing up of softening materials consists in the electrostatic attraction between the e.g. due to washing alkali negatively charged fiber surface and positively charged plasticizer particles.
- Water-insoluble quaternary ammonium compounds containing two long chain alkyl or alkenyl radicals are used. Commonly used connections are Ditallow dimethyl ammonium chloride or distearyl dimethyl ammonium chloride. Because such connections but as ecological are of concern, increasingly used difatty acid trialkanolamine ester salts by reaction a trialkanolamine with technical fatty acids and subsequent quaternization can be obtained, such as Methyl-N- (2-hydroxyethyl) -N, N-di (talgacyloxyethyl) ammonium methosulfate.
- fabric softeners are offered in the form of aqueous dispersions.
- EP 043 622 B1 proposed an aqueous stable dispersion which contains 8 to 22% by weight of a water-insoluble cationic fabric softener, and a viscosity-regulating system containing 0.5 to 6% by weight C 10-24 hydrocarbons, C 10-24 fatty acids or C 10-24 fatty acid esters from fatty acids with short-chain alcohols or C 10-24 fatty alcohols and 0.05 to 1% by weight of a water-soluble cationic polymer.
- the addition of polymers for viscosity control often leads to reduced performance of the fabric softener. Agents without polymeric viscosity regulators are described in DE 36 02 089 C2.
- the compositions contain a fatty alcohol with 10 to 24 carbon atoms, the weight ratio between cationic softeners to fatty alcohols being between 3.5: 1 and 6: 1.
- Ethoxylated amines are used as emulsifiers.
- Solid agents are known from German patent application 42 32 448 A1 which contain quaternary difatty acid trialkanolamine ester salts and a hydroxy compound selected from the group of fatty alcohols, fatty alcohol polyglycol ethers, polyol fatty acid partial esters and carbohydrates and which are suitable for the production of liquid, aqueous plasticizer compositions (with 1 to 50% by weight). -% active substance).
- the weight ratio between quaternary esteramine salt and hydroxy compound should be between 9: 1 and 1: 1.
- a disadvantage of these agents is that relatively large amounts of ecologically unsatisfactory nitrogen-containing compounds are still used.
- EP 497 769 A2 proposes acidic, aqueous fabric softeners which contain pentaerythritol esters as a softening component in amounts between 1 and 25% by weight and 0.1 to 10% by weight of a nonionic emulsifier and are therefore ecologically harmless.
- the object of the invention was therefore to provide stable, aqueous textile plasticizer dispersions To produce the basis of largely biodegradable ingredients with advantageous ecotoxicological properties. It has now been found that combinations of biodegradable, water-insoluble fatty substances with emulsifiers in certain quantitative ratios leads to efficient means when the zeta potential of the aqueous Dispersions exceeds a certain value.
- the invention therefore relates to fabric softeners in the form of an aqueous dispersion of an anti-aging component, wherein the finishing component, based on the weight of the fabric softener, is from 0.5 to 20 %
- the finishing component based on the weight of the fabric softener, is from 0.5 to 20 %
- the weight ratio between fat and emulsifiers is between 10: 1 and 0.5: 1 and the proviso that the zeta potential the aqueous dispersion at a pH of 7 and a temperature of 25 ° C at least + 30 mV is.
- zeta potential is a common method for characterizing solid / liquid dispersions (RJ Hunter, Zeta Potential in Colloid Science, pages 150 to 162, Academic Press, New York 1981).
- Dispersed particles can become electrically charged, for example by adsorption of ions on their surface.
- An electrical double layer forms on the surface of these electrically charged particles, which is firmly connected to the particles and causes an apparent increase in volume.
- This solid layer is enveloped by a movable and diffuse ion layer.
- the potential ⁇ 0 on the particle surface now drops linearly within the solid ion layer with the thickness ⁇ to the value ⁇ ⁇ in order to decrease exponentially to the value 0 in the diffuse layer.
- the potential difference between the inner solid ion layer ⁇ ⁇ and the point within the diffuse ion layer at which the potential has decreased to 1 / e • ⁇ ⁇ is called the zeta potential.
- the rate of migration is measured depending on the size of the particles to be examined either by means of light microscopic observation or, especially for smaller particles, by means of laser correlation spectroscopy (W. Demtröder, laser spectroscopy: basics and techniques, 2nd edition, Springer-Verlag, Berlin 1991, chapters 12.7 to 12.7.2).
- the high positive zeta potential of the dispersions means that the dispersed particles completely can pull up the negatively charged fibers and by completely covering the fibers with hydrophobic, long-chain alkyl residues a good softening effect is achieved.
- Means are particularly suitable here have the highest possible zeta potential over a wide pH range, as is present in the wash liquor.
- Dispersions according to the invention which not only have a zeta potential of not only at a pH of 7 are particularly preferred have at least + 30 mV, but also at a pH of 8, which is often in the wash liquor during reached in the rinse cycle, still show at least a zeta potential of + 25 mV (temperature in each case 25 ° C.).

It is essential that the weight ratio between fat and Emulsifier is between 10: 1 and 0.5: 1 and the amounts of the ingredients are adjusted so that the zeta potential the dispersion at a pH of 7 and 25 ° C is at least + 30 mV.
