Abstract

The invention describes a stable liquid washing agent or liquid cleaning agent having a yield point and very good dispersing properties. The agents contain anionic and nonionic surfactants as well as inorganic salt and cosurfactant. The invention also relates to the use of the liquid washing agent or liquid cleaning agent, and to a method for manufacturing it.

First claim

What is claimed is:

1. A liquid washing or cleaning agent having a yield point, comprising:
5 to 20 wt % anionic surfactant selected from the group consisting of sulfonate surfactants, sulfate surfactants, and mixtures thereof;
1 to 15 wt % nonionic surfactant selected from the group consisting of alkoxylated fatty alcohols having a degree of alkoxylation ≧4, alkoxylated fatty acid alkyl esters, fatty acid amides, alkoxylated fatty acid amides, polyhydroxy fatty acid amides, alkyl phenol polyglycol ethers, amine oxides, alkylpolyglucosides, and mixtures thereof;
0.5 to 10 wt % of an inorganic salt; and
0.5 to 5 wt % of a cosurfactant selected from the group consisting of 1-hexanol, 1-heptanol, 1-octanol, 1,2-octandiol, glycerol monostearate, and mixtures thereof.

2. The liquid washing or cleaning agent according to claim 1 , wherein the anionic surfactant is selected from the group consisting of C 9-13 alkylbenzenesulfonates, olefinsulfonates, C 12-18 alkanesulfonates, ester sulfonates, alk(en)yl sulfates, fatty alcohol ether sulfates, and mixtures thereof.

3. The liquid washing or cleaning agent according to claim 2 , wherein the anionic surfactant comprises C 9-13 alkylbenzenesulfonates and fatty alcohol ether sulfates.

4. The liquid washing or cleaning agent according to claim 1 , wherein the inorganic salt is selected from the group consisting of sodium chloride, potassium chloride, sodium sulfate, sodium carbonate, potassium sulfate, potassium carbonate, sodium hydrogen carbonate, potassium hydrogen carbonate, calcium chloride, magnesium chloride, and mixtures thereof.

5. The liquid washing or cleaning agent according to claim 1 , wherein the cosurfactant is a C 12 to C 18 fatty alcohol having a degree of alkoxylation ≦3.

6. The liquid washing or cleaning agent according to claim 1 , wherein the liquid washing or cleaning agent contains dispersed particles.

7. The liquid washing or cleaning agent according to claim 6 , wherein the dispersed particles are capsules, abrasive substances, and/or insoluble constituents of the washing or cleaning agents.

8. The liquid washing or cleaning agent according to claim 1 , wherein the washing or cleaning agent is free of thickening agents.

9. The liquid washing or cleaning agent according to claim 1 , wherein the washing or cleaning agent additionally contains a C 12 to C 18 fatty acid.

10. The liquid washing or cleaning agent according to claim 1 , wherein it further comprises at least one enzyme.

11. The liquid washing or cleaning agent according to claim 1 , wherein it is free of borax, boric acids, boronic acids, or salts or esters thereof.

12. The liquid washing or cleaning agent according to claim 1 , wherein it contains no glycerol and/or 1,2-propylene glycol.
