Abstract:
The present invention relates to dermocosmetic compositions comprising a compound comprising the structural element of the formula I where the radical Z has the following meaning: H, C 1 -C 22 alkyl group, C 6 -C 10 -aryl group, C 1 -C 22 -alkoxy group or a C 6 -C 10 -O-aryl group substituted by a C 1 -C 22 -alkyl or C-C 22 -alkoxy group, and the radicals R 1 to R 6 , independently of one another, have the following meaning: H, C 1 -C 22 -alkyl group, C 6 -C 10 -aryl group, O, OH, C 1 -C 22 -alkoxy group or a C 6 -C 10 -O-aryl group substituted by a C 1 -C 22 -alkyl or C 1 -C 22 -alkoxy group, it being possible for R 5 and R 6 to be bridged in such a way that a five- to eight-membered ring is formed and, in the case of a five-membered ring, this ring may be part of an oligomer as a result of covalent bonds at positions 3 and 4. The invention furthermore relates to the use of said compounds in dermocosmetic formulations and the use of the dermocosmetics according to the invention for reducing skin or hair damage caused by free radicals. The invention furthermore relates to the use of the compounds according to the invention for increasing the stability of dermocosmetic formulations.
