<p>The present invention relates to novel dithiolane compounds of formula (I) below: formula (I), in which Y denotes 0, NR1 or S; R1 denotes a hydrogen atom; a saturated linear C1-C20 or branched C3-C20 or unsaturated C2-C20 alkyl hydrocarbon- based group; an aryl group optionally substituted with one or more hydroxyls and/or with one or more C1-C8 alkoxy radicals; R denotes a hydrogen atom; a saturated linear C1-C20 or branched C3-C20 or unsaturated C2-C20 alkyl hydrocarbon- based group; a radical having the following formula (Ia), in which n = 0, 1, 2, 3 or 4; x = 0, 1, 2 or 3 and R3, which may be identical or different, denote a hydrogen atom or a linear or branched C1-C4 alkyl such as methyl, ethyl or isopropyl; the radical 4-methyl dithiolane when Y denotes NH; when Y denotes NHR1 and R1 is other than hydrogen, R and Ri may form a ring. The invention also relates to the uses of these compounds for reinforcing the natural antioxidant protection of the skin against oxidative stress caused especially by UV radiation.</p> |
