PURPOSE: To obtain a light-filtering cosmetic emulsion increased in protection index, screening out UV radiation of wavelengths between 280 and 400nm, thermally and photochemically stable and having good feeling to user. CONSTITUTION: This light-filtering cosmetic emulsion is obtained by compounding 2,4,6-tris[p-(2'-ethylhexyl-1'-oxycarbonyl)anilino]-1,3,5-triazine into an oil phase and compounding partially or completely neutralized benzene 1, 4-[3-methylidenecamphormethylsulphonic)]acid represented by the formula A is H, an alkali metal, N(R)4 <+> (R is H or a 1-4C alkyl or hydroxyalkyl) or M<n+> /n group [M<n+> is polyvalent metal cation in which (n) is 2, 3 or 4, preferably Ca<2+> , Z<2+> , Mg<2+> , Ba<2+> , Al<3+> or Zr<4+> ]} into an aqueous phase, preferably in an amount of 0.1-10wt.%, preferably 1-6wt.%, respectively, based on the acid. The emulsion is free from stickiness and exhibits remarkable perpetuity without leaving whitish thin film on skin after application.
