Use of amines and amides for the stabilization of organic micronized uv absorbers

A cosmetic composition comprising

• (a) 0.1 to 20% b.w. of a micronized benzophenone UV absorber of formula (1),
• (b) 0.1 to 10% b.w. of a methoxydibenzoylmethane derivative and
• (c) 0.1 to 50% b.w. of an amine or an amide,
• wherein
• R1 and R2 independently from each other are C1-C20alkyl;
• C2-C20alkenyl;
• C3-C10cycloalkyl;
• C3-C10cycloalkenyl;
• or R1 and R2 together with the linking nitrogen atom form a 5- or 6-membered heterocyclic ring;
• n1 is a number from 1 to 4;
• when n1=1,
• R3 is a saturated or unsaturated heterocyclic radical;
• hydroxy-C1-C5alkyl;
• cyclohexyl optionally substituted with one or more C1-C5alkyl;
• or phenyl optionally substituted with a heterocyclic radical, aminocarbonyl or C1-C5alkylcarboxy;
• when n1 is 2,
• R3 is an alkylene-, cycloalkylene, alkenylene or phenylene radical which is optionally interrupted by —O—, —NH—, a carbonyl- or a carboxy group;
• a radical of formula *—CH2—C≡C—CH2—*;
• or R3 together with A forms a bivalent radical of the formula
• wherein
• n2 is a number from 1 to 3;
• when n1 is 3,
• R3 is an alkantriyl radical;
• when n1 is 4,
• R3 is an alkanetetrayl radical;
• A is —O—;
• or —N(R5)—;
• and
• R5 is hydrogen;
• C1-C5alkyl;
• or hydroxy-C1-C5alkyl.
