摘要

Dyeing composition in a medium, preferably water comprises at least a dye comprising direct dyes or dye precursors and propylene glycol derivative. Dyeing composition in a medium, preferably water comprises at least a dye comprising direct dyes or dye precursors and propylene glycol derivative of formula R 1(OC 3H 6) nOR 2, where the moiety OC 3H 6is optionally branched. R 1H, 1-6C alkyl or 2-6C acyl; R 22-6C alkyl or 6-30C aryl; and n : 1-6. Independent claims are included for: (1) a process of applying the composition on the keratinous fibers for a sufficient time to obtain desired color, followed by rinsing; and (2) an kit for dyeing comprising the composition and a composition containing an oxidizing agent.
