Abstract

The present invention provides a composition that comprises at least one peptide with a sequence length of 6-12 amino acids, where 2-5 of those amino acids are cysteines for the treatment of the hair, including animal and human hair, without the use of chemicals harmful to the hair fiber and consumer health and uses of said compositions in shampoo, lotion, serum, cream, conditioner, foam, elixir, oil, aerosol or mask.

Claims (10)

1. A peptide composition for hair treatment comprising: at least one peptide sequence consisting essentially of SEQ ID NO: 412 or SEQ ID NO: 409 provided that the at least one peptide sequence does not comprise SEQ ID NO: 951 or SEQ ID NO: 432; at least one excipient suitable for dermatological use; wherein the at least one peptide sequence comprises at least 15% cysteine amino acid content; and wherein the peptide composition is a lotion or cream.

2. The peptide composition of claim 1 , wherein the concentration of the at least one peptide is between about 0.001% and about 20% (w/w).

3. The peptide composition of claim 1 , further comprising at least one excipient selected from the group consisting of anionic surfactant, amphoteric surfactant, cationic surfactant, non-ionic surfactant, preservative, thickener, naturally -derived polymer, humectant, silicone, organic oil, protein, fragrance, vitamin, emollient ester, alkanolamide, amine, buffer, pH adjustor, salt, aliphatic alcohol, UV filter, amine oxide, chelate, fatty acid, antimicrobial agent, antibacterial agent, PEG material, polymer, anti-static agent, and alcohol.

4. The peptide composition of claim 1 , further comprising at least one compound selected from the group consisting of preservative, thickener, naturally -derived polymer, humectant, silicone, organic oil, protein, fragrance, vitamin, emollient ester, alkanolamide, amine, buffer, pH adjustor, salt, aliphatic alcohol, UV filter, amine oxide, chelate, fatty acid, antimicrobial agent, antibacterial agent, PEG material, polymer, anti-static agent, alcohol, and mixtures thereof.

5. The peptide composition of claim 1 , further comprising a fragrance, an oil or a mixture thereof.

6. The peptide composition of claim 1 , further comprising a dying agent, or a dye linked to the N or C terminal of the at least one peptide sequence.

7. A hair treatment composition comprising the peptide composition of claim 1 .

8. The peptide composition of claim 1 , wherein the concentration of the at least one peptide is between 0.01% and 5% (w/w).

9. The peptide composition of claim 1 , wherein the at least one excipient suitable for dermatological use is selected from the group consisting of cetearyl alcohol, dicaprylic ether, cetyl esters, behentrimonium chloride, polysorbate 20, hydrolyzed wheat protein, hydrolyzed wheat starch, citric acid, tocopherol, phenoxyethanol, potassium sorbate, benzyl alcohol, potassium hydroxide, and a crosslinked polymer C 10-30 alkyl acrylate.
