摘要:
A porous silica particle with the small specific surface area and large pore volume, which is contained as the scrubbing agent in the cleansing cosmetics is provided. The porous silica particle has high collapsibility, and therefore the damage of the skin can be prevented. A porous silica particle according to the present invention has: an average circularity of 0.1 to 0.5; a pore volume of 0.1≦Pv
