Ornithine derivatives, a process for their preparation, methods of their use and a composition comprising them

摘要

The present invention relates to new compounds, which are N delta -substituted ornithine derivatives, having the formula (I)HOOC-CH(NH2)-(CH2)3-NH-(X)h-(CH2)j-(CHOH)k-(CH2)m-(O)n-(CH2)p-Rin which R represents a hydrocarbon alkyl radical or a perfluorinated alkyl radical, X is a divalent radical chosen from -CO-O-, -CO-NH- and -SO2-, h, j, k, m and n are, independently, zero or 1 and p is zero to 4, a salt of a compound of formula (I), an optical isomer of D or L configuration thereof or a mixture thereof. The invention also relates to a process for the preparation of these compounds, to their use, especially in cosmetics, and to compositions, especially cosmetic compositions, comprising them.
