<P>PROBLEM TO BE SOLVED: To provide a pasty organopolysiloxane elastomer composition which is excellent in storage and stability of blending or the like to cosmetics or the like. <P>SOLUTION: The pasty organopolysiloxane elastomer composition includes (I) organopolysiloxane elastomer fine particles, obtained by addition polymerizing an organopolysiloxane mixture containing (i) an organohydrogen polysiloxane represented by general formula (1) and (ii) an organopolysiloxane represented by general formula (2), and (II) an oil agent in liquid form at 25°C. In the general formula (1), each R<SP POS="POST">1</SP>is the same as or different from each other and is 1-8C monovalent hydrocarbon group not having an aliphatic unsaturated group, a is an integer of 1 or more, b is an integer of 0 or more, a+b is an integer of 80 or more, and each X is the same as or different from each other and is hydrogen atom or R<SP POS="POST">1</SP>. In the general formula (2), each R<SP POS="POST">2</SP>is the same as or different from each other and is 1-8C monovalent hydrocarbon group not having an aliphatic unsaturated group, each R<SP POS="POST">3</SP>is the same as or different from each other and is 2-8C monovalent hydrocarbon group having an unsaturated group at the terminal, c is an integer of 1 or more, d is an integer of 0 or more, c+d is an integer of 80 or more, and each Y is the same as or different from each other and is R<SP POS="POST">2</SP>or R<SP POS="POST">3</SP>. <P>COPYRIGHT: (C)2013,JPO&INPIT |
