Cosmetic composition, useful e.g. as caring, cleansing and/or makeup product for skin of body or face, lips, eyebrows, lashes, nails and hair, or antisun or self-tanning products, comprises a new or know lysine derivative in a medium

摘要

Cosmetic composition comprises at least one lysine derivative (I) in a medium. Cosmetic composition comprises at least one lysine derivative of formula R1C(O)NHCH((CH 2) 4Y1)C(O)NHR2NHC(O)CH((CH 2) 4Y2)NHC(O)R1a (I), or its salts, solvates and/or isomers in a medium. R1, R1a : linear 2-30C-alkyl or branched 3-30C-alkyl (both optionally saturated and optionally substituted by one or more groups comprising OH, NH 2or COOH and/or optionally interrupted by one or more nonadjacent oxygen atoms, nonadjacent nitrogen atoms and/or sulfur); R2 : linear 1-20C-alkyl(ene) or branched 3-20C-alkyl(ene) (both optionally saturated and optionally interrupted by one or more nonadjacent oxygen atoms, nonadjacent nitrogen atoms and/or sulfur); Y1, Y2 : -NR3R4 or -N +>(R3)(R4)(R5) (An ->); R3, R4 : linear saturated 1-20C-alkyl or unsaturated 2-20C-alkyl, optionally saturated branched 3-20C-alkyl, or H; R5 : linear saturated 1-20C-alkyl or unsaturated 2-20C-alkyl, optionally saturated branched 3-20C-alkyl (all optionally substituted by one or more hydroxy) or H; and An ->anion or anionic mixture. An independent claim is included for the lysine derivative (I).
