Patent ID: 8709457

Claim:
A composition comprising, in a physiologically acceptable medium, a compound of formula (II): wherein (i) R 1 and R 2 represent a hydrogen atom, or (ii) R 1 represents a hydrogen atom and R 2 represents a saturated C 1 -C 6 or unsaturated C 2 -C 6 linear alkyl group or saturated or unsaturated C 3 -C 6 branched alkyl group, substituted with one or more groups, which may be identical or different, selected from the group consisting of —OH, —SiMe 3 , —CO 2 R 6 and —F; or (iii) R 1 and R 2 represent a saturated C 1 -C 6 or unsaturated C 2 -C 6 linear alkyl group or saturated or unsaturated C 3 -C 6 branched alkyl group, optionally substituted with one or more groups, which may be identical or different, selected from the group consisting of −OR 5 , —SiMe 3 , —CO 2 R 6 and —F; or (iv) R 1 and R 2 form, together with the nitrogen atom which bears them, a saturated heterocycle with 5 to 7 ring members and optionally comprising another heteroatom chosen from sulphur and oxygen, this heterocycle being optionally substituted with 1 to 3 linear C 1 -C 4 or branched C 3 -C 4 alkyl group(s) optionally substituted with one or more OH groups; R 5 representing a hydrogen atom, or a linear C 1 -C 3 or branched C 3 saturated, or C 2 -C 3 unsaturated alkyl group; R 6 representing a hydrogen atom or a linear C 1 -C 4 or branched C 3 -C 4 saturated alkyl group; R 3 represents a hydrogen atom or a linear C 1 -C 6 saturated alkyl group, or —OR 3 represents a phosphate group; it being possible for the two groups R 3 to form, together, an isopropylidene group; R 4 represents a hydrogen atom or —OR 4 represents a phosphate group; with the proviso that 2,3,4-trihydroxybutanamide is excluded, a salt thereof, an isomer thereof, or a salt thereof; and at least one cosmetic ingredient selected from the group consisting of an oil, a wax, a thickener, a film-forming polymer, a preserving agent, a fragrance, a filler, a UV-screening agent, a bactericide, an odour absorber, a dyestuff, a cosmetic active agent, a plant extract, an antioxidant, sand a surfactant.
