Definitions
- the present invention relates to aqueous dispersions, the fatty substances and emulsifiers contain, as a fabric softener, which is characterized by a high positive zeta potential Mark dispersion.
- Textile treatment agents that have a softening effect on laundry are well known. They are usually used in the last rinse of a machine wash and give the laundry a pleasant, soft feel, as it is a distinctive one Have sorption capacity on a wide variety of fiber surfaces. The occupancy the fiber with the long-chain molecules leads to a sliding effect between the fibers and thus prevents the water or dry rigidity required for the hard grip of the fabric responsible for.
- a possible adsorption mechanism for drawing up softening Materials consist in the electrostatic attraction between the e.g. by Alkaline wash negatively charged fiber surface and positively charged plasticizer particles.
- Statements about the size and the sign of the surface charge can be obtained by measuring the so-called zeta potential, which is the galvanic voltage at the diffuse electrochemical double layer at the phase boundary between the surface of a solid, for example a dispersed plasticizer, and a liquid, for example the washing liquor.
- zeta potential is the galvanic voltage at the diffuse electrochemical double layer at the phase boundary between the surface of a solid, for example a dispersed plasticizer, and a liquid, for example the washing liquor.
- Water-insoluble quaternaries are usually used as fabric softening agents
- Ammonium compounds containing two long chain alkyl or alkenyl radicals are used. Commonly used compounds are ditallow dimethyl ammonium chloride or distearyl dimethyl ammonium chloride. Because such connections are ecologically questionable apply, increasingly used di-fatty acid trialkanolamine salts by reaction a trialkanolamine with technical fatty acids and subsequent quaternization are obtained, such as methyl-N- (2-hydroxyethyl) -N, N-di (tallow acyloxyethyl) ammonium methosulfate.
- fabric softeners are offered in the form of aqueous dispersions.
- the problem arises that the viscosity of the dispersion increases with an increasing proportion of active substance, which makes handling by the consumer more difficult, and furthermore the stability of such products is insufficient.
- 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 preparation 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 invention therefore relates to fabric softeners in the form of an aqueous dispersion a finish component, the finish component, based on the weight of the fabric softener, from 0.5 to 20% by weight of at least one nonionic Fat and 0.2 to 10 wt .-% of a water-soluble and / or water-insoluble cationic Emulsifier and 0 to 10 wt .-% of a nonionic emulsifier, wherein the weight ratio between fat and emulsifiers between 10: 1 and 0.5: 1 and the proviso that the zeta potential of the aqueous dispersion at a pH of 7 and a temperature of 25 ° C is at least + 30 mV.
- 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 bonded 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 patient to be examined Particles either by means of light microscopic observation or, in particular for smaller particles, using laser correlation spectroscopy (W. Demtröder, laser spectroscopy: Basics and techniques, 2nd edition, Springer-Verlag, Berlin 1991, chapter 12.7 to 12.7.2).
- the high positive zeta potential of the dispersions leads to the dispersed particles completely on the negatively charged fibers and by the full Wrapping the fibers with hydrophobic, long-chain alkyl residues is a good thing softening effect is achieved.

- 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 of the dispersion at one pH of 7 and 25 ° C is at least + 30 mV. Only then is it possible that in sufficient Put a lot of softening substances on the textile fibers to get a to achieve a good softening effect.
