摘要: A cosmetic composition comprising titanium oxide coated with one or both of silica and alumina or zinc oxide coated with one or both of silica and alumina, and a thickening polymer having a carboxyl group in the side chain, preferably a carboxyvinyl polymer, wherein when 10% by mass of silica- and/or alumina-coated titanium oxide or silica- and/or alumina-coated zinc oxide is dispersed in an aqueous solution containing 0.133% by mass of a carboxyvinyl polymer, the viscosity after the passing of 100 hours is 50% or more of the initial viscosity. A cosmetic composition comprising titanium oxide coated with one or both silica and alumina or zinc oxide coated with one or both of silica and alumina, and a thickening polymer having a carboxyl group in the side chain of the invention, can maintain emulsion stability by thickening of polymer for a long period of time and can be widely and suitably used for ultraviolet shielding cosmetic materials or the like having preparation form stability.

摘要: To provide a cosmetic composition having excellent ultraviolet protection against both UVB and UVA, causing neither unpleasant whitening to the applied skin nor skin irritation, and ensuring good feeling on use and high safety and high stability without causing decomposition of the ingredients blended in the cosmetic material, such as organic ultraviolet absorber. A cosmetic composition obtained by using fine particulate titanium oxide and fine particulate zinc oxide each surface-treated with silica, alumina or alumina/silica and having a primary particle size of 0.01 to 0.2 μm in combination and blending titanium oxide and zinc oxide at a mass ratio of 1:4 to 2:3, wherein SPF is maintained as compared with the case where the mass ratio of titanium oxide to zinc oxide is 1:0, and when applied to a thickness of 10 μm, the whiteness W value measured using the CIE color specification system is 20 or less.
