新規なポリ不飽和化合物、これらの化合物の製造方法、およびこれらの化合物を含む組成物
Document Type and Number:
Japanese Patent JP5306819
Kind Code:
B2
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.
