<P>PROBLEM TO BE SOLVED: To provide an oil-in-water silicone emulsion composition, which is excellent in storage stability, can form, even without using a tin catalyst, a cured film that exhibits a satisfactory elasticity, through removal of a water fraction, and contains little low molecular weight silicone. <P>SOLUTION: The oil-in-water silicone emulsion composition includes: (A) 100 pts.mass of a polyorganosiloxane that contains in each molecule at least two silicon-bonded hydroxyl or hydrolyzable groups; (B) 0.1 to 200 pts.mass of a colloidal silica; (C) 1 to 100 pts.mass of an ionic emulsifying agent; (D) 0.1 to 50 pts.mass of a polyoxyethylene-polyoxypropylene copolymer-type nonionic emulsifying agent; and (E) 10 to 500 pts.mass of water. <P>COPYRIGHT: (C)2011,JPO&INPIT |
