Abstract: Oligopeptides according to formula (I) and/or (II), R1-Tyr-Pro-Trp-Phe-NH2 (I, SEQ ID NO:1); R1-Tyr-Pro-PhePhe-NH2 (II, SEQ ID NO:2), wherein R1 is linked to the NH2-group of the amino-terminal part of Tyr and is selected from the group consisting of —H; a linear saturated or unsaturated or branched saturated or unsaturated acyl group having 1 to 24 carbon atoms, which may be functionalized by a —OH, —SH, —COOH or —CONH+ group; a sterol or a sphingolipid group which is linked to the amino terminal part of Tyr via a bifunctional linker are disclosed. Cosmetic compositions containing the oligopeptides are also disclosed.

Claim: 1. A method for reducing skin discomfort and/or pain due to an irritating cosmetic agent in a cosmetic composition comprising administering to skin in need thereof a cosmetic composition which comprises a) an oligopeptide according to formula (I) and/or (II): [table included] wherein R1 is linked to the NH2-group of the amino-terminal portion of Tyr and is selected from the group consisting of: (i) —H; (ii) a linear saturated or unsaturated or branched saturated or unsaturated acyl group having 1 to 24 carbon atoms, which acyl group can be functionalized by a —OH, —SH, —COOH or —CONH2 group; and (iii) a sterol or a sphingolipid group which is linked to the amino terminal portion of Tyr by a bifunctional linker; b) an irritating cosmetic agent; and c) optionally, an additive or auxiliary suitable for use in a cosmetic composition; wherein the oligopeptide is present in the composition in an amount sufficient to reduce discomfort and/or pain due to the irritating cosmetic agent when the cosmetic composition is administered cutaneously.
Claim: 2. The method of claim 1, wherein the oligopeptide has a sequence N-Acetyl-Tyr-Pro-Trp-Phe-NH2 (SEQ ID NO:3) or N-Acetyl-Tyr-Pro-Phe-Phe-NH2 (SEQ ID NO:4.
Claim: 3. The method of claim 1, wherein the oligopeptide is present in an amount of from about 0.001 to 1,000 ppm based by weight of the composition.
Claim: 4. The method of claim 3, wherein the oligopeptide is present in an amount of about 0.05 to 500 ppm.
Claim: 5. The method of claim 4, wherein the oligopeptide is present in an amount of about 0.5 to 100 ppm.
Claim: 6. The method of claim 1, wherein the composition is administered to reduce thermal sensitivity of the skin.
Claim: 7. The method of claim 1, wherein the composition is administered to prevent symptoms of skin discomfort and/or pain due to an irritating cosmetic agent.
Claim: 8. The method of claim 1, wherein the composition is administered to ameliorate existing symptoms of skin discomfort and/or pain due to an irritating cosmetic agent.
Claim: 9. The method of claim 1, wherein the composition is administered to sensitive skin.
Claim: 10. The method of claim 1 wherein the irritating cosmetic agent is an alpha-hydroxy or beta-hydroxy acid or a salt or ester thereof.
Claim: 11. The method of claim 10, wherein the alpha-hydroxy acid is selected from C2 to C12 alpha-hydroxy acids and esters thereof with a C2 to C24 alcohol.
Claim: 12. The method of claim 10, wherein the beta-hydroxy acid is selected from C2 to C12 beta-hydroxy acids and esters thereof with a C2 to C24 alcohol.
Claim: 13. The method of claim 10, wherein the acid is selected from the group consisting of lactic acid, citric acid, glycolic acid, gentisic acid, salicylic acid, gluconic acid and heptonic acid.
Claim: 14. The method of claim 1 wherein the irritating cosmetic agent is a retinoid.
Claim: 15. The method of claim 14, wherein the retinoid is selected from the group consisting of retinol, retinal, retinoic acid, retinyl acetate, retinyl palmitate and retinyl ascorbate.
Claim: 16. A cosmetic composition which comprises: a) an oligopeptide according to formula (I) and/or (II) of: [table included] wherein R1 is linked to the NH2-group of the amino-terminal portion of Tyr and is selected from the group consisting of: (i) —H; (ii) a linear saturated or unsaturated or branched saturated or unsaturated acyl group having 1 to 24 carbon atoms, which acyl group can be functionalized by a —OH, —SH, —COOH or —CONH2 group; and (iii) a sterol or a sphingolipid group which is linked to the amino terminal portion of Tyr by a bifunctional linker. b) an irritating cosmetic agent; and c) optionally, an additive or auxiliary suitable for use in a cosmetic composition; wherein the oligopeptide is present in the composition in an amount sufficient to reduce discomfort and/or pain due to the irritating cosmetic agent when the cosmetic composition is administered cutaneously.
Claim: 17. The cosmetic composition of claim 16, wherein the oligopeptide has a sequence N-Acetyl-Tyr-Pro-Trp-Phe-NH2 (SEQ ID NO:3) or N-Acetyl-Tyr-Pro-Phe-Phe-NH2 (SEQ ID NO:4.
Claim: 18. The cosmetic composition of claim 16, wherein the irritating cosmetic agent is an alpha-hydroxy or beta-hydroxy acid or a salt or ester thereof.
Claim: 19. The cosmetic composition of claim 16, wherein the irritating cosmetic agent is a retinoid.
Claim: 20. The cosmetic composition of claim 16, wherein the oligopeptides is present in an amount of from about 0.5 to 100 ppm.
