Abstract: Process for dyeing keratin fibres using a cosmetic composition comprising propane-1,3-diol and a dyeing composition The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising the application to said fibres of an extemporaneous mixture of at least one cosmetic composition comprising propane-1,3-diol and at least one dyeing composition. The invention also relates to a multi-compartment device comprising at least one first compartment containing the cosmetic composition comprising propane-1,3-diol and at least one second compartment containing the dyeing composition.

Abstract: The present invention relates to a non-colouring composition comprising: one or more sulfureous reducing agents, the sulfureous reducing agent(s) being present in proportions ranging from 1.0% to 50.0% by weight relative to the total weight of the composition; one or more phosphoric surfactants; one or more nonionic surfactants other than the phosphoric surfactants; and at least 5.0% by weight of non-liquid fatty substance relative to the total weight of the composition. The invention also relates to a process for permanently reshaping keratin fibres using the composition.

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 coloring of the keratinous human fibers comprising at least one oxidation dye, at least one complex of hydrogen peroxide and a specific polymer and at least one alkaline agent. A subject-matter of the invention is likewise a method for coloring keratinous fibers 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 fibers, the composition is left to stand and the fibers are rinsed.
