An oil-in-water silicone emulsion composition comprising (A) 100 mass parts of a polyorganosiloxane that contains in each molecule at least two silicon-bonded hydroxyl or hydrolyzable groups, (B) 0.1 to 200 mass parts of a colloidal silica, (C) 1 to 100 mass parts of an ionic emulsifying agent, (D) 0.1 to 50 mass parts of a polyoxyethylene-polyoxypropylene copolymer-type nonionic emulsifying agent, and (E) 10 to 200 mass parts water. Such oil-in-water silicone emulsion composition exhibits an excellent storage stability, contains little low molecular weight silicone, and can form, even without the use of a tin catalyst, a cured film that exhibits a satisfactory elasticity, through the removal of the water fraction. |
