A composition for application to the skin to protect the skin from the long wavelength ultraviolet ray comprises a dibenzoylmethane derivative of the following general formula
in which X represents a hydrogen atom, a monovalent metal cation, an organic cation, a linear or branched alkyl group having from 1 to 24 carbon atoms, or a polyoxyalkylene oxide having 2 or 3 carbon atoms, each Y and each Z independently represent a hydroxyl group, a linear or branched alkyl group having from 1 to 24 carbon atoms, or an alkoxy group having from 1 to 24 carbon atoms, or a polyoxyalkylene oxide group having from 2 to 3 carbon atoms, and m and n are independently an integer of from 0 to 3.
The composition is adjustable so as to have an optimum HLB balance and has good compatibility with various cosmetic bases. Further, it does not irritate the skin, is difficult to be percutaneously absorbed and shows continued skin-protecting effects.
一种应用于皮肤以保护皮肤免受长波紫外线伤害的组合物包括通式如下的二苯甲酰甲烷衍生物
其中 X 代表氢原子、一价金属阳离子、有机阳离子、具有 1 至 24 个碳原子的直 链或支链烷基或具有 2 或 3 个碳原子的聚氧化烯;每个 Y 和每个 Z 独立地代表羟基、具有 1 至 24 个碳原子的直链或支链烷基或具有 1 至 24 个碳原子的烷氧基或具有 2 至 3 个碳原子的聚氧化烯;m 和 n 独立地为 0 至 3 的整数。
