Anhydrous composition comprising at least one oxidation dye, at least one complex of hydrogen peroxide, and a specific polymer, and a coloring process using the same

Abstract

A subject-matter of the present invention is an anhydrous composition in the form of a paste or in the pulverulent form for the colouring of human keratinous fibres comprising at least one oxidation dye, at least one complex of hydrogen peroxide and of a specific polymer and at least one alkaline agent. A subject-matter of the invention is likewise a method for colouring keratinous fibres in which the following stages are carried out: the above mentioned anhydrous composition is mixed with an aqueous composition, advantageously devoid of hydrogen peroxide, and the resulting composition is applied to the keratinous fibres, the composition is left to stand, the fibres are rinsed.
