Abstract
An object of the present invention is to provide a porous silica particle with the small specific surface area and the large pore volume, a method for producing the same, and a cosmetic containing the porous silica particle with such characteristics as the texture improver. The porous silica particle according to the present invention has a structure sparsely packed with silica microparticles. The mean particle diameter is 0.5 to 25 μm, the specific surface area measured by the BET method is 5 to 60 m/cm, and the pore volume is 0.35 to 2.0 ml/g. In the pore size distribution of the porous silica particles (X axis: pore diameter, Y axis: value obtained by differentiating the pore volume by the pore diameter), the most frequent pore diameter (D) satisfies 100<D<4000 [nm].
