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.

First claim

The invention claimed is:

1. 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.

2. The cosmetic composition of claim 1 , wherein the multifunctional monomer comprises citric acid or a derivative thereof which is triethyl citrate.

3. The cosmetic composition of claim 1 , wherein the multifunctional monomer further comprises an unsaturated dicarboxylic monomer.

4. The cosmetic composition of claim 3 , wherein the unsaturated dicarboxylic monomer is selected from the group consisting of vinyl-containing maleic acid, maleic anhydride, fumaric acid, fumaryl chloride, and acroylchloride.

5. The cosmetic composition of claim 1 , wherein the diol comprises a saturated or unsaturated C3-C12 diol.

6. The cosmetic composition of claim 1 , wherein the diol is selected from the group consisting of 1,8-octanediol, ethylene diol, propylene diol, poly(ethylene glycol), poly(propylene glycol), 1,3-propanediol, ethanediol, and cis-1,2-cyclohexanediol.

7. The cosmetic composition of claim 1 , wherein the amino acid is selected from the group consisting of cysteine, serine, threonine, histidine, phenylalanine, tryptophan and tyrosine, or a derivative thereof which is S-benzyl-L-cysteine.

8. The cosmetic composition of claim 1 , wherein the multifunctional monomer comprises citric acid, the diol comprises 1,8-octanediol, and the amino acid is selected from the group consisting of the L-amino acids Alanine (Ala), Arginine (Arg), Asparagine (Asn), Aspartic acid (Asp), Cysteine (Cys), Glutamic acid (Glu), Glutamine (Gln), Glycine (Gly), Histidine (His), Isoleucine (Ile), Leucine (Leu), Lysine (Lys), Methionine (Met), Phenylalanine (Phe), Proline (Pro), Serine (Ser), Threonine (Thr), Tryptophan (Trp), Tyrosine (Tyr) and Valine (Val).

9. The cosmetic composition of claim 1 , wherein the PLP is further polymerized or crosslinked.

10. The cosmetic composition of claim 1 , wherein the composition is anhydrous.

11. The cosmetic composition of claim 10 , wherein the at least one additional cosmetically acceptable ingredient is selected from the group consisting of the structuring agent, the gelling agent which is a hydrophobic gelling agent, the powder, the filler, or a combination of two or more thereof.

12. The cosmetic composition of claim 11 , wherein the composition is in the form of the non-compressed powder, the compressed powder or stick, the cosmetic paste, the mascara which is water-proof mascara, the lipstick or the lip gloss.

13. The cosmetic composition of claim 1 , wherein the solvent comprises water as major ingredient of the composition, and wherein the at least one additional cosmetically acceptable ingredient comprises the gelling agent which is a hydrophilic gelling agent.

14. The cosmetic composition of claim 1 , wherein the composition is in the form of the mascara, wherein the mascara comprises washable mascara, the lipstick, the lip gloss, the lip balm, the cosmetic lotion, the cosmetic cream, or the hair care product, wherein the hair care product comprises a gel, shampoo or a conditioner.

15. The cosmetic composition of claim 1 , wherein the composition is multi-phasic and comprises the liquid fatty phase, water as the solvent, or a combination of the liquid fatty phase and water, and the at least one additional cosmetically acceptable ingredient comprises the emulsifier.

16. The cosmetic composition of any of claims 11 , 13 and 15 , wherein the at least one additional cosmetically acceptable ingredient further comprises a colorant, photoprotective agent, secondary film-former, a cosmetically active agent or a cosmetic adjuvant, wherein the cosmetic adjuvant is selected from the group consisting of emollients, moisturizers, fibers, preservatives, chelators, fragrances, neutralizing agents, and combinations of two or more thereof.

17. The cosmetic composition of claim 1 , wherein the solvent comprises water, a water-miscible compound, an ester, oil, a fatty alcohol, or a combination of two or more thereof.

18. 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.

19. 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.
