摘要：

Disclosed is a granulated silica particle which provides excellent feeling of use especially when applied to the skin. This granulated silica particle is formed by using, as a constitutional element, a scale-like silica having a thickness of a primary particle of 0.001-0.1 µm and a silanol group (SiOH) per unit specific surface area of 20-70 µmol/m². This granulated silica particle has an average particle diameter of 1-50 µm, and a compressive strength of 1-4 MPa.
