Oxidation dye composition in the subject-matter comprising one or more ether (s) cationic cellulose (s), one or more derivative (s) of diaminopyrazolone, and one or more other (s) of the oxidation dye (s).

摘要

Composition for dyeing keratin fibers, preferably human keratin fibers such as hair, comprises, in a medium, a cationic cellulose ether having 4000-10000 anhydroglucose units having at least one substituent of amine compounds (a) or (b), 2,3-diaminopyrazolone derivatives and/or their addition salts (compounds (A)), and one or more second oxidation dyes (compounds (A)). Composition for dyeing keratin fibers, preferably human keratin fibers such as hair, comprises, in a medium, cationic cellulose ether having 4000-10000 anhydroglucose units having at least one substituent of amine compounds of formula (R 4R 5R 6R 9N +) (X 2 -) (a) or (R 1R 2R 3R 8N +) (X 1 -) (b), 2,3-diaminopyrazolone derivatives and/or their addition salts (compounds (A)), and one or more second oxidation dyes (compounds (A)). R 1-R 5methyl or ethyl; R 68-24C alkyl or aralkyl of which the alkyl part is 8-24C; R 9divalent group, which allows the connection to anhydroglucose group, -(B 1) q-CH 2-CHOH-CH 2- or -CH 2CH 2-; R 8divalent group, which allows the connection to anhydroglucose group, -(A) p-CH 2-CHOH-CH 2- or -CH 2CH 2-; p, q : 0 or 1; A, B 1-(CH 2CH 2O) n-; n, n1 : 1-100; and X 1 -, X 2 -anion. Independent claims are included for: (1) a process for oxidation coloring of keratin fibers comprising applying the composition on the fibers; and (2) a device with several compartments comprising at least a first compartment containing the coloring composition and at least a second compartment comprising at least an oxidizing agent.
