Disclosed herein are benzylidene compounds represented by the formula (I): ##STR1## wherein A represents ##STR2## (wherein B represents hydrogen atom or an acetyl group, W represents hydrogen atom or --CH.sub.2 --CH.sub.2 --CO--O--R, X.sup.1, X.sup.2 and X.sup.3 represent independently hydrogen atom, a hydroxyl group or a methoxyl group (two or three of them may be the same or all of them may be different), Y represents oxygen atom or imino group (--NH--), Z represents a methyl group or a phenyl group, and R represents a straight chain alkyl group having 1 to 18 carbon atoms, or branched or cyclic alkyl group having 3 to 18 carbon atoms, provided that when A is ##STR3## R is not an alkyl group having 1 to 2 carbon atoms, and when A is ##STR4## and X.sup.1, X.sup.2 and X.sup.3 are hydrogen atom, R is not an alkyl group having 1 to 2 carbon atoms), a cosmetic composition containing the same and an ultraviolet absorber comprising the same.
本文揭示的是公式(I)所代表的苯甲醛化合物:##STR1## 其中A代表##STR2##(其中B代表氢原子或乙酰基,W代表氢原子或--CH.sub.2 --CH.sub.2 --CO--O--R,X.sup.1、X.sup.2和X.sup.3分别独立地代表氢原子、羟基或甲氧基(其中两个或三个可能相同或全部不同),Y代表氧原子或亚胺基(--NH--),Z代表甲基或苯基,R代表具有1至18个碳原子的直链烷基或具有3至18个碳原子的支链或环状烷基,但当A为##STR3##时,R不是具有1至2个碳原子的烷基,当A为##STR4##且X.sup.1、X.sup.2和X.sup.3为氢原子时,R不是具有1至2个碳原子的烷基),以及含有它的化妆品组合物和包含它的紫外线吸收剂。
