Abstract (en)

[origin: FR2772607A1] The use of phenolic amides (I) in cosmetic and dermopharmaceutical compositions to depigment or whiten the skin and / or hair. The phenolic amides have the following formula: R = H, 1-24C linear, branched or cyclic, saturated or unsaturated alkyl, (optionally hydroxylated), aryl (optionally substituted by one or more of OH, NH2, COOH, NO2, OR5, COOR6, and NR7R8), or -COR9; R1 and R2 = H, 1-24C linear, branched or cyclic, saturated or unsaturated alkyl, (optionally hydroxylated), aryl (optionally substituted by one or more of OH, NH2, COOH, NO2, OR5, COOR6, NR7R8), OH, OQ1, COQ2, COOQ3, NQ4Q5, CONQ6Q7, SQ8, and CH2OQ9; R3 and R4 = H, 1-24C linear, or branched saturated or unsaturated alkyl, (optionally hydroxylated), 1-24C cyclic saturated or unsaturated alkyl, aryl (optionally substituted by one or more of OH, NH2, COOH, NO2, OR5, COOR6, and NR7R8); R5 = 1-24C alkyl; R6 = 1-24C alkyl; R7 = H or 1-24C alkyl; R8 = H or 1-24C alkyl; R9 = 1-24C linear, branched or cyclic, saturated or unsaturated alkyl, (optionally hydroxylated), aryl (optionally substituted by one or more of OH, NH2, COOH, NO2, OR5, COOR6, and NR7R8); Q1 - Q9 = H, 1-24C linear, branched or cyclic, saturated or unsaturated alkyl, (optionally hydroxylated), aryl (optionally substituted by one or more of OH, NH2, COOH, NO2, OR5, COOR6, and NR7R8), an amino acid residue or a cyclic or non-cyclic carbohydrate residue except for those compounds in which R1 = R2 = R3 = H and R4 = methyl, the OH group being placed para to the amide group.
