Japanese Patent JP6208123

B2

A subject-matter of the present invention is a composition for dyeing keratin fibers, in particular human keratin fibers such as the hair, comprising: i) at least one non-ionic ether of polyoxyalkylenated fatty alcohols of formula (I), and also the optical isomers and geometrical isomers thereof; in which formula (I): R denotes a saturated or unsaturated and linear or branched C10-C30 hydrocarbon radical, R′ denotes a saturated or unsaturated and linear or branched C10-C30 hydrocarbon radical, which may be substituted by a hydroxyl radical, n is an integer between (1) and approximately (100) inclusive, and Alk represents a linear or branched, preferably linear, (C1-C6) alkylene group such as ethylene or propylene, preferably ethylene, ii) at least one fatty substance, iii) optionally at least one surfactant other than i), iv) at least one direct dye and/or at least one oxidation dye, v) optionally at least one basifying agent, vi) optionally at least one chemical oxidizing agent, and the fatty substance content of the composition representing in total at least 25% by weight relative to the total weight of the composition. The present invention also relates to a method using this composition and to a multi-compartment device that is suitable for the use of said method. R—(O-Alk)n-O—R′  (I)
