Abstract: A novel long wave UV ray absorber comprising a dibenzoylmethane derivative effectively shuts out UV-A which causes a harmful action on skin. The absorber is insoluble in water, organic solvents, oily substances, sebum and the like, so that percutaneous absorption does hardly take place and the absorber is scarcely removed by water or sweat, thus keeping a high efficacy.
