Abstract
The present invention relates to a composition for dyeing keratin fibres, comprising: a) one or more liquid fatty substances; b) one or more amphoteric surfactants of formula (I) below: R a'-C(O)—NH—CH—(CH2)—N(B)(B′)(I) in which: B represents the group —CH—CH—O—X′; B′ represents the group —(CH)Y′< with z=1 or 2; X′ represents the group —CH—C(O)OH, —CH—C(O)OZ′, —CH—CH—C(O)OH or —CH—CH—C(O)OZ′, or a hydrogen atom; Y′ represents the group —C(O)OH, —C(O)OZ″, —CH—CH(OH)—SOH or the group —CH2-CH(OH)—SO-Z″; Z′ and Z″ represent, independently of each other, a cationic counterion derived from an alkali metal or alkaline-earth metal, such as sodium, an ammonium ion or an ion derived from an organic amine; Rrepresents a C-Calkyl or alkenyl group derived from an acid R—C(O)OH, which is preferably present in copra oil or in hydrolysed linseed oil, an alkyl group, especially a Cgroup and its iso form, or an unsaturated Cgroup and n represents an integer ranging from 1 to 10 and preferably from 1 to 5, or quaternized forms thereof; c) one or more thickening polymers chosen from polymers bearing sulfonic unit(s), polymers bearing sugar unit(s) and mixture thereof; d) one or more oxidation dye precursors and e) one or more chemical oxidizing agents, The present invention also relates to a process using this composition.
