Abstract
The present disclosure relates to a dye composition comprising water in an amount of at least 40% by weight, relative to the total weight of the dye composition. The present disclosure also relates to a process for dyeing keratin fibers, such as human keratin fibers, using the dye composition as disclosed herein. The dye composition also comprises at least one dye chosen from oxidation dye precursors and direct dyes; at least one surfactant chosen from nonionic and anionic surfactants; at least one hydroxyethylcelluloses; at least one fatty substance; wherein the weight ratio of the total amount of surfactants to the total amount of the at least one fatty substance is greater than or equal to 1.75; and also comprising at least one cationic associative polymer. The present disclosure also relates to a multi-compartment kit comprising a first compartment comprising at least one dye composition as disclosed herein, and a second compartment comprising at least one, oxidizing composition.
