Abstract
The invention relates to the use of a composition comprising at least one conductive polymer in a cosmetically acceptable medium, said polymer being in soluble form in said medium, as, or for the manufacture of, cosmetic products for giving a visual effect to human keratin fibers and more particularly the hair, and also, when said conductive polymer absorbs in the visible region, as, or for the manufacture of, cosmetic products intended to color said fibers. The invention also relates to the corresponding treatment process.
Claims19
The use of a composition comprising at least one conductive polymer in a cosmetically acceptable medium, said polymer being in soluble form in said medium, as an agent for giving a visual effect to human keratin material and more particularly to human keratin fibers.
The use of a composition comprising at least one conductive polymer in a cosmetically acceptable medium, said polymer being in soluble form in said medium, for the manufacture of cosmetic products for giving a visual effect to human keratin material, more particularly to keratin fibers.
The use as claimed in one of the preceding claims, characterized in that the conductive polymer corresponds to formula (III) or (IIIbis), in which at least one radical R1 to R4 of formula (IIIa) or R1 or R2 of formula (IIIb) or (IIIbis) represents a solubilizing group of the carboxylic acid type, in neutralized or normeutralized form, optionally linked to the ring via a spacer, preferably a linear or branched C1-C20 alkyl radical, the other radical(s) representing a hydrogen atom.
The use as claimed in any one of the preceding claims, characterized in that the conductive polymer(s) is(are) present in proportions of at least 0.001% by weight, more particularly of at least 0.01% by weight, preferably of at least 0.1% by weight and even more preferably of at least 0.5% by weight relative to the total weight of the composition.
The use as claimed in any one of the preceding claims, characterized in that the conductive polymer(s) is(are) present in proportions of at most 50% by weight, more particularly at most 30% by weight, preferably at most 10% by weight, relative to the total weight of the composition.
The use as claimed in any one of the preceding claims, characterized in that the cosmetically acceptable medium is chosen from the group formed by water and a water/solvent mixture.
The use as claimed in any one of the preceding claims, characterized in that it also comprises at least one nonionic, anionic, cationic, amphoteric or zwitterionic surfactant.
The use as claimed in any one of the preceding claims, characterized in that the composition is applied to the wet or dry fibers, and then in evaporating the composition medium or leaving the composition medium to evaporate at between 20 and 120° C., preferably between 20 and 80° C., until the fibers are dry.
A composition for dyeing human keratin fibers and more particularly the hair, characterized in that it comprises an effective amount of at least one conductive polymer in a cosmetically acceptable medium, said polymer being in soluble form in said medium, absorbing in the visible spectrum and chosen from the group formed by homopolymers and copolymers comprising:
