(57) [Summary] (Modified) [Object] To provide a novel oil-in-water type silicone emulsion composition which is suitable for use in cosmetics and the like, which is excellent in usability and has good long-term storage stability. [Structure] (1) General formula R 3 Si (OSiR 2 ) n OSiR 3 (R is a monovalent hydrocarbon group having 1 to 6 carbon atoms, and n is 500 to 10 on average. 000), an organopolysiloxane (2) 2 An organopolysiloxane having a viscosity of 1 to 500 centistokes at 5 ° C., (3) a polyoxyalkylene-modified organopolysiloxane having an HLB value of 5 to 12 and (4) an ionic surfactant, Ratio of [(1) component + (2) component] / [(3) component + (4) component] is in the range of 95/5 to 50/50, and (4) component is 0.5 to 5 in [(3) component + (4) component]. It is characterized by being emulsified in water so as to contain 20% by weight. |
