Summary:An objective of the present invention is to provide a solid water-in-oil emulsion cosmetic that significantly improves stability at high temperatures, while maintaining an excellent feeling in use (a smooth and watery texture) that is obtained by blending a powder into an internal water phase. The present invention relates to a solid water-in-oil emulsion cosmetic containing an internal water phase in which an internal phase powder, including hydrophilic titanium oxide, is dispersed in an aqueous medium, and an external oil phase that is thickened or solidified with a wax and/or a gelling agent, wherein the solid water-in-oil emulsion cosmetic contains a cationic dispersant and/or an amphoteric dispersant for dispersing the internal phase powder; and the internal phase powder contains 5.0% by mass or more of the hydrophilic titanium oxide relative to the total amount of the cosmetic.
