Composition used for e.g. dyeing keratin fibers (hair), comprises non-ionic ether of polyoxyalkylenated fatty alcohols, fatty substance e.g. silicones, surfactant, direct dye or oxidation dye, basifying agent and chemical oxidizing agent
Composition comprises: (a) at least one non-ionic ether of polyoxyalkylenated fatty alcohols (I)； (b) at least 25 wt.% of at least one fatty substance； (c) optionally at least one surfactant other than (I)； (d) at least one direct dye and/or at least one oxidation dye； (e) optionally at least one basifying agent； and (f) optionally at least one chemical oxidizing agent. Composition comprises: (a) at least one non-ionic ether of polyoxyalkylenated fatty alcohols of formula (R-(O-A1) n-O-R1)) (I)； (b) at least 25 wt.% of at least one fatty substance； (c) optionally at least one surfactant other than (I)； (d) at least one direct dye and/or at least one oxidation dye； (e) optionally at least one basifying agent； and (f) optionally at least one chemical oxidizing agent. R : 10-30C hydrocarbyl； R1 : 10-30C hydrocarbyl (optionally substituted by OH)； n : 1-100； and A1 : (1-6C)alkylene comprising ethylene (preferred) or propylene. Independent claims are also included for: (1) dyeing keratin fibers, preferably human keratin fibers (hair), comprising applying the composition to the fibers； and (2) multi-compartment device comprising either a first compartment with composition (A2) and at least a second compartment with composition (B1), where the compositions of the compartments are mixed before application to give a composition ((A2)+(B1)) or the first compartment with composition (A3), the second compartment with composition (B3) and at least a third compartment with composition (C1), where the compositions of the compartments are mixed before application to give a composition ((A3)+(B2)+(C1)).La présente invention a pour objet une composition de coloration des fibres kératiniques, en particulier de fibres kératiniques humaines tels que les cheveux, comprenant : i) au moins un éther non ionique d'alcools gras polyoxyalkyléné, de formule (I) : R-(O-Alk) -O-R' (I), ainsi que leurs isomères optiques, isomères géométriques ； formule (I) dans laquelle : - R désigne un radical hy
