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 tocopheryl radical or the like, an amino acid residue, or a sugar residue. The invention also concerns the compositions, in particular cosmetic and/or dermatological compositions containing at least one compound of formula (I) as well as their use as whitening and/or depigmenting agent, and the cosmetic method using said compositions.
