Abstract
Lysine derivatives, the salts of the derivatives, their optical isomers of D or L configuration, or their mixtures, the derivatives containing an N.sup..epsilon. -alkoxy or N.sup..epsilon. -alkenoxycarbonyl group of formula: ##STR1## in which: R represents a linear or branched C.sub.13 -C.sub.24 alkyl radical, the C.sub.16 radical being branched, or a linear or branched C.sub.8 -C.sub.24 alkenyl radical. The lysine derivatives are used in cosmetic, pharmaceutical hygiene or food compositions.
Claims3
