Abstract: The present invention provides a composition for skin or hair which achieves an excellent UV absorption in a wide range of UV wavelength from the UV-A to the UV-B without inhibiting the effect of the alkyl ?,?-diphenylacrylate and the ?-cyano-?,?-diphenylacrylate (e.g. octocrylene) which serve to improve the photostability of dibenzoylmethane derivative. The composition for skin or hair comprises: (a) a dibenzoylmethane derivative, (b) an alkyl ?,?-diphenylacrylate and/or an ?-cyano-?,?-diphenylacrylate (e.g. octocrylene), and (c) a specific benzalmalonate derivative (e.g. di(2-ethylhexyl)-4-methoxybenzalmalonate).

Abstract: The present invention is a sunscreen cosmetic comprising 4-(1,1-dimethylethyl)-4?-methoxydibenzoylmethane, a benzotriazole derivative represented by the following general formula (I), and ethylhexyl 2-cyano-3,3-diphenylacrylate. The present invention is a sunscreen cosmetic comprising hexyl diethylaminohydroxybenzoylbenzoate and a benzotriazole derivative represented by the following general formula (I). (In this formula, R?=a straight chain alkyl group of C1-C6 and R?=a straight chain alkyl group of C1-C3.) The object of the present invention is to provide a sunscreen cosmetic that prevents staining due to secondary adhesion to clothing.
