Abstract: A water-in-oil emulsion cosmetic, in which an ultraviolet scattering agent is uniformly dispersed in a base, an excellent ultraviolet protective effect is stably imparted, and whitishness is suppressed. A water-in-oil emulsion cosmetic is described, comprising the following components (a), (b), (c), and (d): (a) titanium dioxide surface-treated with a fatty acid and/or an alkylalkoxysilane; (b) an amphiphilic substance which is solid at normal temperature; (c) a linear silicone oil; and (d) a volatile hydrocarbon oil.

Abstract: A cosmetic composition in the form of a W/O emulsion includes: (A) 1 to 20% by weight of a plate-like powder which has been surface-treated with an alkylalkoxysilane; (B) 0.1 to 10% by weight of an oil that is solid at temperature of 25° C.; (C) 0.5 to 60% by weight of an oil selected from the group consisting of a hydrocarbon oil, an ester oil, and an ether oil, having a viscosity at 25° C. of 500,000 mPa·s or less; and (D) water, wherein a weight ratio of the component (B) to the component (A), (B)/(A), is 0.01 to 5.
