Abstract: The 1-aryl-2-aryloxyethane compounds of Formula 1 in which n and m are zero or equal to 1, provided that n+m=1, R1 and R2 in particular representing hydrogen atoms, R3 and R4 in particular representing hydrogen atoms, halogen atoms, hydroxy or alkoxy groups, and R5 in particular representing hydrogen atoms, hydroxy, alkyl, alkoxy, amino or nitro groups, in cosmetic compositions intended for anti-ageing and/or depigmenting and/or anti-inflammatory and/or wound-healing care.
Abstract: Compounds, ceramide analogues, having a cyclic structure derived from cyclopropane, cyclobutane or cyclopentane, the ring bearing two chains consisting of an amide function. Each amide function is attached to the ring by the nitrogen atom of the function and carries a hydrocarbon chain derived from a fatty acid. The amide functions can be cis or trans relative to one another. Processes for the preparation of these novel compounds as well as pharmaceutical and/or cosmetic compositions containing them.
