Abstract

PURPOSE: To inexpensively obtain blood serum or blood plasma separating composition without losing function even if radiant rays by ionization are irradiated by preparing a composition having a specific gravity which lies between that of blood serum and blood corpuscle components from a specific base oil and a hydrophobic silica fine powder.
CONSTITUTION: Said base oil is selected from a group comprising purified castor oil, glyceride of ricinoleic acid or an acetylized derivative thereof or a mixture thereof. Said hydrophobic silica fine powder has an average particle size of about 16mμ and is prepared by applyng hydrophobic imparting treatment to silica obtained from hydrolysis of silicon tetrachloride. Both components are compounded so as to adjust the specific gravity to an intermediate specific gravity (about 1.03W 1.060) of blood corpuscle component and blood serum or plasma and, generally, said hydrophobic silica fine powder is compounded in an amount of about 14.5W 21.2pts.wt. per 100pts.wt. base oil. Further, in order to hold a three dimensional structure of constituent components, a structure forming agent is added appropirately and, in order to improve dispersibility of said hydrophobic silica fine powder, a surfuctant is added in an appropriate amount.
