Abstract:
1. A cosmetic composition comprising, in a cosmetically acceptable medium, at least one fluorescent dye that is soluble in the medium and at least one non-associative thickening polymer chosen from: (i) crosslinked acrylic acid homopolymers; (ii) crosslinked 2-acrylamido-2-methylpropanesulphonic acid homopolymers and the partially or totally neutralized acrylamide crosslinked copolymers thereof; (iii) ammonium acrylate homopolymers or copolymers of ammonium acrylate and of acrylamide; (iv) dimethylaminoethyl methacrylate homopolymers quaternized with methyl chloride; and copolymers of dimethylaminoethyl methacrylate quaternized with methyl chloride and of acrylamide; (v) nonionic guar gums; (vi) biopolysaccharide gums of microbial origin; (vii) gums derived from plant exudates; (viii) hydroxypropyl and carboxymethyl celluloses; (ix) pectins; and (x) alginates; wherein the at least one fluorescent dye is chosen from dyes of formula F1 and F3  wherein: R R R optionally interrupted with at least one hetero atom; R X is chosen from: a being equal to 0 or 1; Y n is an integer at least equal to 2 and at most equal to the number of cationic charges present in the fluorescent compound; wherein the composition does not comprise, as the at least one fluorescent dye, 2-[2-(4-dialkylamino)phenylethenyl]-1-alkylpyridinium wherein the alkyl radical of the pyridinium nucleus represents a methyl or ethyl radical, the alkyl radical of the benzene nucleus represents a methyl radical, and wherein the counterion is a halide.
