Abstract
The present disclosure relates to a dye composition comprising at least one dye, at least one nonionic surfactant, at least one anionic surfactant, at least one fatty alcohol and at least one non-ethoxylated fatty acid ester; the weight ratio of the total amount of fatty alcohols to the total amount of nonionic and anionic surfactants being greater than 0.5 and the water content comprising at least 55% by weight. The disclosure similarly relates to a process for dyeing keratin fibers, for example human keratin fibers, using such a composition, and also to a multi-compartment device comprising the dye composition in the first compartment, and an oxidizing composition in the second compartment.
