An object of the present invention is to provide a powdery slaked calcite type calcium silicate material which exhibits a high oil absorption.nThe solution of the present invention relates to a powdered slaked-type calcium silicate type calcium silicate material, characterized in that: (1) the SiO2/CaO molar ratio in the material is 1.5 or more, and (2) the material is fine. The cumulative pore volume of the pore diameter of 3.6 to 200 nm is 0.9 cc/g or more, and the cumulative pore volume of 3.6 to 5000 nm is 2.6 cc/g or more. |
