摘要

Vitamin complexes, nanoparticles desdit complexes, processes for their preparation, their compositions, their cosmetic uses and cosmetic treatment process Complex consisting of at least one molecule of 5- (1,2-dihydroxy-ethyl) -3,4-dihydroxy -5H-furan -2-one or derivative covalently bound to at least one hydrocarbon radical of formula (A) as follows: wherein: - m = 1, 2, 3, 4, 5 or 6; - m = 0, 1, 2, 3, 4, 5 or 6; and represents the linkage to the 5- (1,2-dihydroxyethyl) -3,4-dihydroxy-5H-furan-2-one or derivative molecule. Nanoparticles of said complex, processes for preparing said complex and said nanoparticles, their compositions, their cosmetic uses as well as a cosmetic treatment method for the skin and / or the face and / or the scalp are also described.
