Novel system for solubilising fat-soluble organic sun filters

Abstract

The present invention relates to a cosmetic or dermatological composition in the form of an emulsion, comprising: (a) a fat-soluble photoprotective system consisting of one or more fat-soluble UV filter(s) selected from: (i) hexyl 2-[4-(diethylamino)-2 hydroxybenzoyl]benzoate, (ii) 2,4-bis[4-(2-ethythexyloxy)-2-hydroxyphenyl]-6-(4-methoxyphenyl)-1,3,5-triazine, (iii) butyl methoxydibenzoylmethane, (iv) ethythexyl triazone, and (v) diethylhexyl butamido triazone: (b) a solubilising system of the fat-soluble photoprotective system (a), comprising C12-C15 alkyl benzoate in a quantity greater than or equal to 80% by weight, preferably greater than or equal to 90% by weight, relative to the total weight of the solubilising system; and (c) one or more particulate organic UV filters, which are in particular hydro-dispersed and are selected from: (vi) 5,6,5′,6′-tetraphenyl-3,3′-(1,4-phenylene)-bis[1,2,4]triazine, (vii) methylene bis-benzotriazolyl tetramethylbutylphenol, (viii) tris-biphenyl triazine; characterised in that: —the fat-soluble photoprotective system (a) constitutes between 3% and 19% by weight, preferably between 5% and 15% by weight, relative to the total weight of the composition; —and —the solubilising system (b) constitutes between 15% and 30% by weight, relative to the total weight of the composition; the composition not comprising ethylhexyl salicylate, octocrylene, ethylhexyl methoxycinnamate, isoamyl methoxylcinnamate, homosalate, para-aminobenzoic acid (PABA), octyl dimethyl PABA, 3-methylbenzylidene 30 camphor, 4-methylbenzylidene camphor, benzophenone-3 and/or benzophenone-4.
