NOVEL SYSTEM FOR SOLUBILISING FAT-SOLUBLE ORGANIC SUN FILTERS

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-ethylhexyloxy)-2-hydroxyphenyl]-6-(4-methoxyphenyl)-1,3,5-triazine, (iii) butyl methoxydibenzoylmethane, (iv) ethylhexyl 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. La présente invention a trait à une composition cosmétique ou dermatologique, sous forme d'émulsion, comprenant : (a) un système photoprotecteur liposoluble, consistant en un ou plusieurs filtre(s) UV liposoluble(s) choisi(s) parmi : (i) l'hexyl 2-[4-(diéthylamino)-2-hydroxybenzoyl]benzoate, (ii) la 2,4-bis[4-(2-éthylhexyloxy)-2-hydroxyphényl]-6-(4-méthoxyphényl)-1,3,5- triazine, (iii) le butyl méthoxydibenzoylméthane, (iv) l'éthylhexyl triazone, et (v) la diéthylhexyl butamido triazone; (b) un système solubilisant dudit système photoprotecteur liposoluble (a), comprenant du C12-C15 alkyl benzoate dans une quantité supérieure ou égale à 80 % en poids, de préférence supérieure ou égale à 90 % en poids, par rapport au poids total du système solubilisant; et (c) un ou plusieurs filtre(s) UV organique(s) particulaire(s), en particulier hydrodispersés, choisi(s) parmi :
