Abstract
The present invention relates to an anhydrous solid composition for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising a particular chemical oxidizing agent and a polymer comprising at least one heterocyclic vinyl monomer. The present invention also relates to a packaging article containing said composition. The present invention also relates to processes for dyeing keratin fibres using said composition or said packaging article. Finally, the present invention relates to the use of said composition or of said packaging article for dyeing keratin fibres, and in particular human keratin fibres such as the hair.
Claims21
An anhydrous solid composition for dyeing keratin fibres comprising:
- (a) one or more oxidation bases,
- (b) one or more chemical oxidizing agents chosen from alkali metal percarbonates, alkaline-earth metal percarbonates and mixtures thereof,
- (c) one or more polymers comprising at least one heterocyclic vinyl monomer, and
- (d) optionally one or more oxidation couplers,
- wherein the composition does not comprise any additional chemical oxidizing agent that is different from the one or more chemical oxidizing agents (b).
A packaging article comprising:
- i) an envelope defining at least one cavity, the envelope comprising water-soluble and/or liposoluble fibres;
- and
- ii) an anhydrous solid dyeing composition comprising:
- (a) one or more oxidation bases,
- (b) one or more chemical oxidizing agents chosen from alkali metal percarbonates, alkaline-earth metal percarbonates and mixtures thereof,
- (c) one or more polymers comprising at least one heterocyclic vinyl monomer, and
- (d) optionally one or more oxidation couplers;
- it being understood that the anhydrous solid dyeing composition is in one of the cavities defined by the envelope i).
