PROBLEM TO BE SOLVED: To provide a composition for external use in which the light stability of a dibenzoylmethane derivative is improved. A dibenzoylmethane derivative and a benzalmalonate derivative represented by the following formula (1) are blended. [Chemical 1] [In Formula (1), R < 1 >, R < 2 >, R < 3 > and R < 4 > are C1-C20 alkyl groups, respectively. It is preferred that R 2 , R 3 and R 4 are methyl groups. R 1 is preferably a 2-ethylhexyl group. The dibenzoylmethane derivative is preferably 4-tert-butyl-4′-methoxydibenzoylmethane. [Selection figure] None |
