  • Publication number: 20100331177
    Abstract: The present invention provides amorphous silica particles having high oil absorbency and high structural characteristics, wherein the oil absorbency is hardly decreased even when a high load is applied to the amorphous silica particles. In particular, amorphous silica particles are provided, wherein the maximum value of ?Vp/?Rp (where Vp is the pore volume [mm3g] and Rp is the pore radius [nm]) is 20 mm3/nm·g?1 or more in the pore distribution curve obtained by a benzene adsorption isotherm, and the pore peak radius when the ?Vp/?Rp value is maximum is from 20 nm or more to 100 nm or less.
