The present invention relates to a process for cosmetic treatment of the skin, comprising the application to the skin of a composition comprising a compound (I) with R, R' and X as defined in the description and S* a monosaccharide or polysaccharide.

Process for treating keratin materials using amide, acid or ester c-glycoside derivatives, and cosmetic composition containing same

The process for preparing 2-hydroxyphenyl alkenyl benzotriazole compounds and the process for preparing siloxane compounds containing 2-hydroxyphenyl benzotriazole function are disclosed.

Process for preparing 2-hydroxyphenyl alkenyl benzotriazole compounds; use of the said compounds obtained via the process in the synthesis of siloxane compounds containing a 2-hydroxyphenylbenzotriazole function

A process for synthesizing para-phenylenediamine derivative compounds containing a pyrolidinyl group, and substituted by a nitrogenous radical, wherein the para-phenylenediamine derivative compounds are chosen from those of formula (I): Intermediates containing a pyrrolidinyl group bearing a nitrogenous radical are also disclosed herein.

Process for preparing pyrrolidinyl-functional para-phenylenediamine derivatives substituted by a nitrogenous radical, and intermediate compounds

The invention concerns novel silicon compounds derived from ascorbic acid consisting of a silicon-containing chain or of silanes, comprising at least a radical A of formula (I) wherein: at least one of the radicals L is a divalent radical for fixing A on the silicon chain. The invention further concerns methods for preparing said compounds, compositions, in particular cosmetic or pharmaceutical, containing them, and their use as antioxidant and/or anti-free radical agent, particularly for treating oxidant stress, for treating the effects of exposure to the sun and for preventing ageing.
