POROUS SILICA PARTICLE HAVING SURFACE SMOOTHNESS, METHOD FOR PRODUCTION OF THE POROUS SILICA PARTICLE, AND COSMETIC COMPRISING THE POROUS SILICA PARTICLE |
摘要 |
Disclosed are porous silica-based particles having high surface smoothness, a method for producing the porous silica-based particles, and a cosmetic comprising the porous silica-based particles. The porous silica-based particles have an average particle diameter of 0.5 to 30 µm and have a surface smoothness of a level to such an extent that, when the entire surface of the particle is observed from a photograph thereof taken by a scanning electron microscope (SEM) with a magnifying power of 10,000, a foreign matter attached to the surface thereof can be hardly seen. |
