Abstract:
Disclosed is the use of a UV filter combination, comprising (a) a first UV filter selected from benzylidene malonates of formula (1), wherein R1 methyl; ethyl; propyl; or n-butyl; if R1 is methyl, then R is tert. butyl; formula (II); formula (III); a radical of formula (1a); or a radical of formula (1b); wherein R2 and R3, independently from each other are hydrogen; or methyl; R4 is methyl; ethyl; or n-propyl; R5 and R6 independently from each other are hydrogen; or C1-C3alkyl; if R1 is ethyl; propyl; or n-butyl, then R is isopropyl; and (b) a second UV filter selected from (b1) Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine; (b2) Butyl Methoxydibenzoylmethane; (b3)Diethylhexyl Butamido Triazone; (b4) Ethylhexyl Triazone; (b5) Diethylamino Hydroxy Benzoyl Hexyl Benzoate; (b6) Ethylhexyl Methoxycinnamate; (b7) Ethylhexyl Salicylate; (b8) Homosalate; (b9) Octocrylene; (b10) micronized Methylene Bis-Benzotriazolyl Tetramethylbutylphenol; (b11) Phenylbenzimidazole Sulfonic Acid; (b12) Titanium Dioxide; (b13) micronized Tris-Biphenyl Triazine; and (b14) micronized (2-{4-[2-(4-Diethylamino-2-hydroxy-benzoyl)-benzoyl]-piperazine-1-carbonyl}-phenyl)-(4-diethylamino-2-hydroxy-phenyl)-methanone;(b15) 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 (b1)-(b14); for the protection of human and animal hair and skin against UV radiation.
