Abstract

A description is given of compositions comprising a) one or more substances selected from the group consisting of hydrogen peroxide and hydrogen peroxide donor substances, b) water, c) one or more polymers having thickening properties and d) one or more substances selected from the group consisting of hydroxypyridones and salts thereof. The compositions are notable more particularly for their advantageous shelf lives.

First claim

b) water;
c) at least one polymer having at least one thickening property and having a molecular weight of more than 5000 g/mol; and
d) 0.5 to 1000 ppm of at least one substance selected from the group consisting of compounds of the formula (I) and salts thereof

in which R1 is H or a C 1 -C 4 alkyl radical and R2 is H, an unsubstituted or halogen-substituted, branched or unbranched C 1 -C 20 alkyl radical, an unsubstituted or halogen-substituted C 5 -C 8 cycloalkyl radical, an unsubstituted or halogen-substituted C 6 -C 10 aryl radical or an unsubstituted or halogen-substituted, branched or unbranched C 7 -C 20 aralkyl radical;
wherein the viscosity of the composition is 50 to 100000 mPa·s at 20° C., and wherein the pH of the composition is in the range of 2-7, and wherein the substance selected from the group consisting of compounds of the formula (I) and salts thereof is present in an amount such that the composition exhibits a viscosity stability over 4 weeks from formulation at 40° C. of at least 68%.

2. The composition as claimed in claim 1 , wherein the at least one substance of component a) is selected from the group consisting of hydrogen peroxide, urea peroxide, perborates, persulfates and mixtures thereof.

3. The composition as claimed in claim 1 , wherein the substance of component a) is hydrogen peroxide.

4. The composition as claimed in claim 1 , wherein the at least one polymer having at least one thickening property of component c) is selected from the group consisting of polymers having a C—C backbone, biopolymers, modified biopolymers, associative thickeners and polyalkylene glycols.

5. The composition as claimed in claim 4 , wherein the at least one polymer having at least one thickening property of component c) is selected from the group consisting of polymers having a C—C backbone.

6. The composition as claimed in claim 5 , wherein the at least one polymer having a C—C backbone is a partly or fully neutralized polymer containing sulfo groups.

7. The composition as claimed in claim 6 , wherein the at least one partly or fully neutralized polymer containing sulfo groups is selected from the group consisting of homo- or copolymers of acrylamidomethylpropanesulfonic acid and salts thereof.

8. The composition as claimed in claim 4 , wherein the at least one polymer having at least one thickening property of component c) is selected from the group consisting of biopolymers and modified biopolymers.

9. The composition as claimed in claim 4 , wherein the at least one-polymer having at least one thickening property of component c) is selected from the group consisting of associative thickeners.

10. The composition as claimed in claim 9 , wherein the at least one associative thickener is selected from the group consisting of phosphoric esters.

11. The composition as claimed in claim 4 , wherein the at least one polymer having at least one thickening property of component c) is selected from the group consisting of polyalkylene glycols.

12. The composition as claimed in claim 1 , wherein the at least one compound of component d) is present in the form of the acid or in the form of the alkali metal, alkaline earth metal or amine salt thereof or a salt thereof with a polymeric counterion.

13. The composition as claimed in claim 1 , wherein, in the at least one compound of the formula (I) or in the salt thereof, R1 is methyl and R2 is cyclohexyl or 2,4,4-trimethylpentyl.

14. The composition as claimed in claim 1 , wherein R1 and R2 in the at least one compound of the formula (I) or in the salt thereof are each H.

15. The composition as claimed in claim 1 , which comprises the at least one substance of component d) in an amount of 0.1 ppm to 2% by weight, based on the total weight of the composition.

16. The composition as claimed in claim 1 , which has a pH of 2.5-4.5.

17. A composition for bleaching and/or coloring of hair or a permanent wave formulation, comprising at least one composition according to claim 1 .

18. An oxidative cleanser formulation, comprising at least one composition according to claim 1 .

19. A stain removal gel for pretreatment of laundry, a prewash spray, a stain remover, a surface cleaner, a toilet cleaner, a multifunctional stain removal gel or a bleaching gel, comprising at least one composition according to claim 1 .

20. A method for stabilization of at least one polymer having at least one thickening property in a composition as claimed in claim 1 , comprising the step of adding at least one substance selected from the group consisting of compounds of the formula (I) and salts thereof to the composition.

21. The method as claimed in claim 20 , wherein the at least one polymer having at least one thickening property is a partly or fully neutralized polymers containing sulfo groups.

22. The method as claimed in claim 21 , wherein the at least one partly or fully neutralized polymers containing sulfo groups are selected from the group consisting of homo- or copolymers of acrylamidomethylpropanesulfonic acid and salt thereof.

23. A composition according to claim 1 , in the form of a bleach composition for hair, a developer for a hair dye, or a permanent wave formulation.

24. A composition according to claim 1 , in the form of a bleach composition for teeth or a household cleaner.

25. A composition according to claim 1 , having wherein the viscosity of the composition is 150 to 5000 mPa·s at 20° C.

26. A composition comprising
a) 1% to 10% by weight of at least one substance selected from the group consisting of hydrogen peroxide and hydrogen peroxide-releasing substances;
