Abstract
Disclosed is the use of a UV filter combination, comprising (a) a first UV filter selected from benzylidene malonates of formula (1), wherein Rmethyl; ethyl; propyl; or n-butyl; if Ris methyl, then R is tert. butyl; formula (II); formula (III); a radical of formula (1a); or a radical of formula (1b); wherein Rand R, independently from each other are hydrogen; or methyl; Ris methyl; ethyl; or n-propyl; Rand Rindependently from each other are hydrogen; or C-Calkyl; if Ris ethyl; propyl; or n-butyl, then R is isopropyl; and (b) a second UV filter selected from (b) Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine; (b) Butyl Methoxydibenzoylmethane; (b)Diethylhexyl Butamido Triazone; (b) Ethylhexyl Triazone; (b) Diethylamino Hydroxy Benzoyl Hexyl Benzoate; (b) Ethylhexyl Methoxycinnamate; (b) Ethylhexyl Salicylate; (b) Homosalate; (b) Octocrylene; (b) micronized Methylene Bis-Benzotriazolyl Tetramethylbutylphenol; (b) Phenylbenzimidazole Sulfonic Acid; (b) Titanium Dioxide; (b) micronized Tris-Biphenyl Triazine; and (b) micronized (2-{4-[2-(4-Diethylamino-2-hydroxy-benzoyl)-benzoyl]-piperazine-1-carbonyl}-phenyl)-(4-diethylamino-2-hydroxy-phenyl)-methanone;(b) benzoicacid,4,4-[[3-[1,3,3,3-tetramethyl-1-[trimethylsilyl)oxy]-1-disiloxanyl]propyl]amino]-1,3,5-triazine-2,4-diyl]diimino]bis-, dibutyl ester wherein the UV filter combination comprises at least 2 UV filters of component (b)-(b); for the protection of human and animal hair and skin against UV radiation.
