Abstract:
A composition for the oxidation dyeing of keratinous fibers, comprising:(a) at least one enzyme of the laccase type; (b) at least one conditioning agent insoluble in aqueous media, chosen from poly-&agr;-olefins, fluorinated oils, vegetable oils, natural waxes, fluorinated waxes, fluorinated gums, fatty acid esters chosen from ethyl and isopropyl palmitates, 2-ethylhexyl palmitate, 2-octyidecyl palmitate, butyl, cetyl and 2-octyidodecyl myristates, hexyl stearate, butyl stearate, dioctyl maleate, hexyl laurate, 2-hexyldecyl laurate and isononyl isononanate, silicones, and amide compounds comprising at least one fatty chain chosen from those of the formula (1): â€ƒin which: R1 is chosen from saturated and unsaturated, linear and branched, C9-C30 hydrocarbon groups, it being possible for these groups to be substituted with at least one substituent chosen from hydroxyl groups optionally esterified with an acid chosen from saturated and unsaturated C16-C30 fatty acids, and Râ€³â€”(NRâ€”CO)nâ€”Râ€²â€” groups in which n is equal to 0 or 1, R is chosen from a hydrogen atom and hydroxyethyl groups, Râ€² and Râ€³ are identical or different and are each chosen from hydrocarbon groups, optionally substituted, in which the sum of the carbon atoms varies from 9 to 30, Râ€² being a divalent group; R2 is chosen from a hydrogen atom, (glycosyl)n groups, (galactosyl)m groups and sulphogalactosyl groups in which n is an integer varying from 1 to 4 and m is an integer varying from 1 to 8; R3 is chosen from a hydrogen atom, saturated and unsaturated C15-C27 hydrocarbon groups, it being possible for these groups to be substituted with at least one C1-C14 alkyl group; R3 may also be chosen from C15-C26 &agr;-hydroxyalkyl groups, wherein the hydroxyl group of said &agr;-hydroxyalkyl group is optionally esterified with an acid chosen from C16-C30 &agr;-hydroxy acids; R4 is chosen from a hydrogen atom, saturated and unsaturated C16-C27 hydrocarbon groups, optionally substituted, and â€”CH2â€”CHOHâ€”CH2â€”Oâ€”R6 groups in which R6 is chosen from C10-C26 hydrocarbon groups, optionally substituted; R5 is chosen from a hydrogen atom and mono- and polyhydroxylated C1-C4 hydrocarbon groups; and (c) at least one oxidation dye.
