Abstract
Disclosed herein is a dye composition comprising water in an amount greater than or equal to 40% by weight, relative to the total weight of the composition, and a process for dyeing keratin fibers, for example, human keratin fibers, using such a composition. This dye composition additionally comprise at least one dye chosen from oxidation dye precursors and direct dyes; at least one surfactant chosen from nonionic surfactants and anionic surfactants; at least one nonionic cellulose modified with at least one group comprising saturated and unsaturated, linear and branched C6-C30 hydrocarbon chains, and at least one cationic associative polymer. Also disclosed herein is a multi-compartment device or kit separately comprising the dye composition and an oxidizing composition.
