Abstract
Disclosed is the use of UV absorbers selected from (a) diphenylacrylates; (a) hydroxyphenyl triazines of formula (1), in which R, Rand Rindependently of one another, are C-Calkyl; (a) benzotriazole derivatives of formula (2), wherein Ris 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); Eis a straight-chain C-Calkyl; Eis a straight-chain C-Calkyl; wherein the total number of carbon atoms in Eplus Eis from 7 to 29; and Ris C-Calkyl; and (a) di-alkyl naphthalate; for stabilizing cosmetic compositions comprising (b) symmetrical triazine derivatives of formula (3), wherein A is a radical of formula (3a); or (3b) Rand Rindependently from each other are hydrogen; C-Calkyl; or C-Caryl; R, Rand Rindependently from each other are hydrogen; or a radical of formula (3c), wherein, in formula (3a), at least one of the radicals R, Rand Rare a radical of formula (3c); R, R, Rand Rindependently from each other are hydrogen; hydroxy; halogen; C-Calkyl; C-Calkoxy; C-Caryl; biphenylyl; C-Caryloxy; C-Calkylthio; carboxy; —COOM; C-C-alkylcarboxyl; aminocarbonyl; mono- or di-C-Calkylamino; C-Cacylamino; 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) cinnamic acid derivatives; and (C) dibenzoylmethane derivatives.
