    • Disclosed is the use of UV absorbers selected from (a 1 ) diphenylacrylates; (a 2 ) hydroxyphenyl triazines of formula (1), in which R 1 , R 2 and R 3 independently of one another, are C 1 -C 18 alkyl; (a 3 ) benzotriazole derivatives of formula (2), wherein R 4 is a random statistical mixture of at least three isomeric branched secondary alkyl groups each having 8 to 30 carbon atoms and having the formula (2a); E 1 is a straight-chain C 1 -C 14 alkyl; E 2 is a straight-chain C 4 -C 15 alkyl; wherein the total number of carbon atoms in E 1 plus E 2 is from 7 to 29; and R 5 is C 1 -C 5 alkyl; and (a 4 ) dialkyl naphthalate; for stabilizing cosmetic compositions comprising (b) symmetrical triazine derivatives of formula (3), wherein A is a radical of formula (3a); or (3b) R 6 and R 10 independently from each other are hydrogen; C 1 -C 18 alkyl; or C 6 -C 12 aryl; R 7 , R 8 and R 9 independently from each other are hydrogen; or a radical of formula (3c), wherein, in formula (3a), at least one of the radicals R 7 , R 8 and R 9 are a radical of formula (3c); R 11 , R 12 , R 13 and R 14 independently from each other are hydrogen; hydroxy; halogen; C 1 -C 18 alkyl; C 1 -C 18 alkoxy; C 6 -C 12 aryl; biphenylyl; C 6 -C 12 aryloxy; C 1 -C 18 alkylthio; carboxy; -COOM; C 1 -C 18 -alkylcarboxyl; aminocarbonyl; mono- or di-C 1 -C 18 alkylamino; C 1 -C 10 acylamino; or -COOH; M is an alkali metal ion; x is 1 or 2; and y is a number from 2 to 10; and a UV-absorber selected from (c 1 ) cinnamic acid derivatives; and (C 2 ) dibenzoylmethane derivatives.
