Abstract

The invention relates to compositions containing a) one or more substances selected from the group of hydrogen peroxide and substances releasing hydrogen peroxide, b) water, d) one or more substances selected from the group consisting of hydroxypyridones and the salts thereof, characterized in that said compositions do not comprise polymers having thickening properties. The compositions are particularly characterized by the advantageous storage stability thereof.

First claim

The invention claimed is:

1. A composition comprising
a) at least one substance selected from the group consisting of hydrogen peroxide and hydrogen peroxide-releasing substances,
b) water, and
d) 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 composition further comprises active antimicrobial ingredients in amounts from 0.001% to 5.0% by weight, based on the total weight of the composition,
with the proviso that the composition does not comprise any polymer having thickening properties.

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 and the hydrogen peroxide is present in the composition in amounts of 0.5 to 20% by weight based on the total weight of the composition.

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

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

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

7. The composition as claimed in claim 6 , which comprises the at least one substance of component d) in amounts of 0.5 to 100 ppm, based on the total weight of the composition.

8. The composition as claimed in claim 1 , which has a pH of 2 to 11.

9. The composition as claimed in claim 8 , which has a pH of 7 to 11.

10. An oxidative cleaner formulation comprising at least one composition according to claim 1 .

11. A composition for oxidative bleaching of fibers or textiles comprising at least one composition according to claim 1 .
