Abstract
The present disclosure relates to a dye composition comprising at least one dye, at least one fatty alcohol, at least one fatty acid ester, at least one surfactant chosen from non-ionic surfactants and anionic surfactants and at least one non-ionic associative polymer, wherein water is present in the dye composition in an amount greater than or equal to 55% by weight. The present disclosure further relates to a process for dyeing keratin fibers, including human keratin fibers, using such a composition and also to a multi-compartment kit separately comprising the dye composition and an oxidizing composition.
