摘要

"compounds, process for their preparation and use, composition, and process for increasing the production of collagen and / or elastin in human skin and / or for the delay or treatment of skin aging". cosmetically acceptable compounds and salts thereof, which correspond to the general formula (i) where: r ^ 1 ^ represents h, -c (o) -r ^ 6 ^, -so ~ 2 ~ -r ^ 6 ^ or -c (o) -xr ^ 6 ^; r ^ 2 ^ and r ^ 4 ^ = independently of each other, represent (ch ~ 2 ~) ~ n ~, -nh ~ 2 ~ or (ch ~ 2 ~) ~ 3 ~ nhc (nh) nh ~ 2 ~; n = 1-4; r ~ 3 ~ = c ~ 1 ~ -c ~ 4 ~ -line or branched alkyl optionally substituted by hydroxyl; r ^ 5 ^ and ^ 6 ^ = independently of each other, represent hydrogen, (c ~ 1 ~ -c ~ 24 ~) -alkyl optionally substituted, c ~ 2-c ~ 24 ~ -alkenyl optionally substituted, phenyl optionally substituted, optionally substituted phenyl-c ~ 1 ~ -c ~ 4 ~ -alkyl or 9-fluorenylmethyl; x = oxygen (-o-) or -nh-; or xr 5 ^ with x = o also represents the esters of 244 -tocopherol, tocotrienol or retinol, with the proviso that r ^ 1 ^ and r ^ 5 ^ do not represent hydrogen and x does not represent oxygen at the same time; the preparation of the compounds of general formula (i); cosmetically active composition comprising at least one compound of formula (i).
