Abstract
Disclosed are cosmetic compositions and methods for making up keratinous tissue using the compositions, as well as methods of making the compositions. The compositions contain a photoluminescent polymer (PLP) which is an oligomeric polyester synthesized from a multifunctional monomer and a diol, and which has grafted thereon an amino acid or an amino acid derivative. The compositions achieve a colorizing and/or UV-protectant effect when applied to keratinous tissue.

A cosmetic composition, comprising a) a photoluminescent polymer (PLP) which is a polyester synthesized from a multifunctional monomer containing two carboxylic acid groups and a functional moiety comprising a carboxylic acid group or a hydroxyl group, and a diol, wherein the photoluminescent polymer has grafted thereon or incorporated into the polymer backbone, an amino acid or an amino acid derivative which is S-benzyl-L-cysteine, b) a solvent and c) at least one additional cosmetically acceptable ingredient comprising a structuring agent, a gelling agent, a powder, a filler, an emulsifier, a liquid fatty phase or a combination of two or more thereof, wherein the composition is selected from the group consisting of a non-compressed foundation powder or stick, a compressed foundation powder or stick, a cosmetic paste, mascara, lipstick, lip gloss, lip balm, a cosmetic lotion, a cosmetic cream, and a hair care product.
A method of making up keratinous tissue, comprising applying to keratinous tissue a cosmetic composition, comprising a) a photoluminescent polymer (PLP) which is a polyester synthesized from a multifunctional monomer containing two carboxylic acid groups and a functional moiety comprising a carboxylic acid group or a hydroxyl group, and a diol, wherein the photoluminescent polymer has grafted thereon or incorporated into the polymer backbone, an amino acid or an amino acid derivative which is S-benzyl-L-cysteine, b) a solvent and c) at least one additional cosmetically acceptable ingredient comprising a structuring agent, a gelling agent, a powder, a filler, an emulsifier, a liquid fatty phase or a combination of two or more thereof, wherein the composition is selected from the group consisting of a non-compressed foundation powder or stick, a compressed foundation powder or stick, a cosmetic paste, mascara, lipstick, lip gloss, lip balm, a cosmetic lotion, a cosmetic cream, and a hair care product.
A method of preparing a cosmetic composition for making up keratinous tissue, comprising formulating a) a photoluminescent polymer (PLP) which is a polyester synthesized from a multifunctional monomer containing two carboxylic acid groups and a functional moiety comprising a carboxylic acid group or a hydroxyl group, and a diol, wherein the photoluminescent polymer has grafted thereon or incorporated into the polymer backbone, an amino acid or an amino acid derivative which is S-benzyl-L-cysteine, b) a solvent and c) at least one additional cosmetically acceptable ingredient comprising a structuring agent, a gelling agent, a powder, a filler, an emulsifier, a liquid fatty phase or a combination of two or more thereof, wherein the composition is selected from the group consisting of a non-compressed foundation powder or stick, a compressed foundation powder or stick, a cosmetic paste, mascara, lipstick, lip gloss, lip balm, a cosmetic lotion, a cosmetic cream, and a hair care product.
