摘要：
UV absorber compositions are described, comprising (a) from 1 to 99% by weight of a hydroxyphenyltriazine compound of formula (I) wherein R1, R2 and R3 are each independently of the others C1-C18alkyl; C2-C10,alkenyl; or phenyl-C1-C4 alkyl; R4 is hydrogen; or C1-C5alkyl; and (b) from 99 to 1% by weight of a further UV absorber selected from the group of (b) hydroxyphenyltriazines that are different from component (a), (b2) benzotriazoles, (b3) dibenzoylmethane derivatives and (b4) camphor derivatives. The compositions are suitable as UV filters in cosmetic compositions
