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.

Abstract: The invention concerns novel polyunsaturated compounds of formula (I) wherein: R1 represents a R?1, -A-R?1 group, R?1 being selected from —COOH, —COOR3, —CONH2, —CONHR3, —CONR3 R4, —CHO, —CH2OH, —CH2OR5, and A represents a C2-C16 alkylene, alkenylene or alkynylene; R2 represents: an optionally substituted aryl group or an optionally substituted heteroaryl group; a sugar residue or, a fatty acid residue optionally branched and/or substituted preferably at the chain terminus and particularly by hydroxy, acetoxy radical or by an optionally protected amino radical; a —OC —(CH2)n CO-tocopheryl (alpha, beta or gamma or delta) group, with 2 $m(F) n $m(F) 10; a —R?2—O—R6 group, wherein R?2 is an optionally substituted arylene group or an optionally substituted heteroarylene group, and R6 represents a hydrogen atom, a straight or branched optionally substituted C 1-C 16 alkyl, a straight or branched optionally substituted C2-C16 alkenyl, or a straight or branched C2-C16 alkynyl group, an optionally substituted tocophe

Abstract: The invention concerns a method for preparing a compound of formula (I), wherein: R3 and R1 represent in particular H and n is greater than 4, said preparation method including performing a Wittig-Horner reaction with a phosphonate on a lactol, so as to obtain a hydroxyester and, optionally a saponification reaction of said hydroxyester.
