PROBLEM TO BE SOLVED: To provide an emulsion in which the particle size is easily controlled, the obtained particle size distribution is narrow, and the emulsion has excellent emulsion stability and compounding stability while having a large particle size. SOLUTION: In producing an O / W type silicone emulsion of a polyorganosiloxane, water having a phase inversion point or higher is added at once to a mixture of a polyorganosiloxane and a surfactant, followed by mixing and stirring. Add water and dilute. |
