Abstract

The present invention relates to a stable liquid washing or liquid cleaning agent comprising an anti-graying polysaccharide. The invention further relates to the use of the liquid washing or liquid cleaning agent and to a method for the production thereof.

Claims

1. A liquid washing or cleaning agent comprising:

a. from 0.1 to 60 wt. % surfactant;

b. from 0.1 to 5 wt. % of a graying-inhibiting polysaccharide;

c. from 0.05 to 1 wt. % of a thickener; and

d. from 1 to 20 wt. % of an inorganic salt.

2. The liquid washing or cleaning agent of claim 1, wherein said graying-inhibiting polysaccharide is selected from the group consisting of carboxymethyl cellulose, ether sulfonic acid salts of starch, ether sulfonic acid salts of cellulose, acidic sulfuric acid ester salts of cellulose, acidic sulfuric acid ester salts of starch, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, methyl hydroxyethyl cellulose, methyl carboxymethyl cellulose, ethyl hydroxyethyl cellulose, and mixtures thereof.

3. The liquid washing or cleaning agent of claim 2, wherein said polysaccharide is carboxymethyl cellulose.

4. The liquid washing or cleaning agent of claim 2, wherein said polysaccharide is sodium carboxymethyl cellulose.

5. The liquid washing or cleaning agent of claim 1, wherein said 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.

6. The liquid washing or cleaning agent of claim 1, wherein said thickener is selected from the group consisting of xanthan, guar, carrageenan, agar agar, gellan, pectin, locust bean flour, and mixtures thereof.

7. The liquid washing or cleaning agent of claim 6, wherein said thickener is xanthan.

8. The liquid washing or cleaning agent of claim 1, further comprising a cellulase.

9. The liquid washing or cleaning agent of claim 1, further comprising an acrylic polymer.

10. Use of the washing or cleaning agent of claim 1 for the washing or cleaning of textile fabrics.

11. A method for producing a micro phase separation in a liquid washing or cleaning agent, said method comprising the step of adding from 0.05 to 1 wt % of a thickener and from 1 to 20 wt % of an inorganic salt to said liquid washing or cleaning agent.

12. The method of claim 11, wherein said liquid washing or cleaning agent comprises a graying-inhibiting polysaccharide.

13. A process for manufacturing a micro two-phase liquid washing or cleaning agent comprising:

0.1 to 60 wt % surfactant;

0.1 to 5 wt % of a graying-inhibiting polysaccharide; and

, 0.05 to 1 wt % of a thickener, said method comprising the step of;

adding from 1 to 20 wt % of an inorganic salt to said liquid washing or cleaning agent.
