Abstract
Lysine derivatives, salts of the derivatives, their optical isomers of D or L configuration, or their mixtures, the derivatives containing an Ne-alkoxy or Ne-alkenoxycarbonyl group and having the formula: in which: R represents a linear or branched C13-C24 alkyl radical or alkenyl radicals, are used in cosmetic, pharmaceutical, hygiene or food compositions, particularly compact compositions.
Claims13
A composition comprising from 0.05 to 80% by weight with respect to the total weight of the composition of at least one compound selected from the group consisting of a lysine derivative having the formula:
- in which R′ represents a linear or branched C13-C24 alkyl or C13-C24 alkenyl radical, the salts of said derivative, the optical isomers of D or L configuration and mixtures thereof, and wherein said composition is a cosmetic, pharmaceutical, hygienic or food composition.
A compact cosmetic composition comprising from 0.05 to 80% by weight with respect to the total weight of the composition of at least one compound to facilitate the compaction of the ingredients of said composition, said compound being selected from the group consisting of a lysine derivative having the formula:
- in which R′ represents a linear or branched C13-C24 alkyl or C12-C24 alkenyl radical, the salts of said derivative, the optical isomers of D or L configuration and mixtures thereof.
A compact pharmaceutical composition comprising from 0.05 to 80% by weight with respect to the total weight of the composition of at least one compound to facilitate the compaction of the ingredients of said composition, said compound being selected from the group consisting of a lysine derivative having the formula:
- in which R′ represents a linear or branched C13-C24 alkyl or C13-C24 alkenyl radical, the salts of said derivative, the optical isomers of D or L configuration and mixtures thereof.
