- 10. A method according to claim 9, wherein said alkanolamine is selected from the group consisting of ethylaminoethanol, methylaminoethanol, dimethylaminoethanol-amine, isopropanolamine, triethanolamine, isopropanoldimethylamine, ethylethanol-amine, 2-butanolamine, choline and serine.
- 11. A method according to claim 2, wherein said alkanolamine is dimethylamino-ethanol.
- 12. A method according to claim 1, wherein said at least one compound is present in an amount of from about 0.1 to about 10% by weight of the composition.
- 13. A method according to claim 4, wherein said composition comprises a mixture of from about 1 to about 5% by weight of alkanolamine and from about 1 to about 5% by weight of tyrosine.
- 14. A method according to claim 1, wherein said composition further comprises a skin irritating ingredient.
- 15. A method according to claim 1, wherein the irritating ingredient is selected from a retinoid, benzyol peroxide, alpha-hydroxyacids and derivatives thereof, salicylic acid, surfactants, soaps, natural plant extracts, sunscreen actives, urea, preservatives.
- 16. A method according to claim 1, wherein said composition is applied to red or inflamed skin.
- 17. A method according to claim 8, wherein said composition is applied to sun burned skin, wind burned skin, or skin that is red or inflamed due to contact with irritating soaps or cleansers.
- 18. A method according to claim 16, wherein said composition is applied to skin that is red or inflamed due to rosacea, atopic dermatitis, or allergic skin reactions.
- 19. A method for ameliorating the irritating effects of a skin irritating composition comprising adding to said composition an effective amount of a compound selected from the group consisting of an alkanolamine; tyrosine; or a mixture thereof; wherein said alkanolamine has the following general formula:
- 20. A method according to claim 11, wherein said alkanolamine is selected from the group consisting of ethylaminoethanol, methylaminoethanol, dimethylaminoethanol-amine, isopropanolamine, triethanolamine, isopropanoldimethylamine, ethylethanol-amine, 2-butanolamine, choline and senne.
- 21. A method according to claim 20, wherein said alkanolamine is dimethylamino-ethanol.
- 22. A method according to claim 19, wherein said at least one compound is present in an amount of from about 0.1 to about 10% by weight of the composition.
- 23. A method according to claim 19, wherein said composition comprises a mixture of from about 1 to about 5% by weight of alkanolamine and from about 1 to about 5% by weight of tyrosine.
- 24. A method according to claim 19, wherein the skin irritating composition comprises an irritant selected from a retinoid, benzyol peroxide, alpha-hydroxyacids and derivatives thereof, salicylic acid, surfactants, soaps, natural plant extracts, sunscreen actives, urea, and preservatives.
