DYE COMPOSITION COMPRISING A HETEROCYCLIC OXIDATION BASE AND AN INDOLE COUPLER

The subject of the present invention is dye composition for keratin fibres, comprising, in suitable dyeing medium, a coupler of formula (I) or addition salts thereof with an acid a particular cationic or noncationic aminopyrazolopyridine derivative. The composition of the present invention makes it possible in particular to obtain a colouring with varied, intense and/or chromatic, aesthetic and relatively nonselective shades which are highly resistant to the various attacks to which the hair may be subjected.

COMPOSITION FOR THE OXIDATION DYEING OF KERATIN FIBERS COMPRISING AT LEAST ONE NONIONIC DERIVATIVE OF CELLULOSE WITH AT LEAST ONE HYDROPHOBIC SUBSTITUENT, AT LEAST ONE OXIDATION BASE OF DIAMINODIAZACYCLOPENTENE TYPE, AND AT LEAST ONE OXIDATION COUPLER, AN OXIDATION DYEING PROCESS, AND KIT

The present disclosure relates to a dye composition for keratin fibers, such as keratin fibers, for example the hair, comprising, in a medium suitable for dyeing: at least one nonionic derivative of cellulose comprising at least one hydrophobic substituent containing from 8 to 30 carbon atoms; at least one oxidation base chosen from diaminodiazacyclopentene derivatives; and at least one oxidation coupler; and a process for dyeing keratin fibers using such a composition.

Composition for dyeing keratin fibers, comprising at least one diamino-N,N-dihydropyrazolone derivative, at least one coupler, and at least one surfactant

Disclosed herein is a composition for dyeing keratin fibers, for example, human keratin fibers such as the hair, comprising at least one oxidation base chosen from diamino-N,N-dihydropyrazolones and the addition salts thereof, at least one coupler, and at least one surfactant chosen from (C8-C30)alkyl ether carboxylic acids and salts thereof, (C12-C30)alkyl polyglucosides, monoglycerolated surfactants, and polyglycerolated surfactants. Also disclosed herein is a method for dyeing keratin fibers comprising applying a composition in accordance with the present disclosure to the keratin fibers. The compositions and methods of the present disclosure may makes it possible to obtain fast coloration of keratin fibers that is resistant to light and/or to washing.
