的とする。However, the cosmetics for skin or hair containing silicone oil or silicone resin have drawbacks such as insufficient adhesion to the skin or hair and stickiness remaining. And was inferior in usability. Moreover, these silicone oils for cosmetics and silicone resins are usually emulsified and dispersed in water using a hydrocarbon-based surfactant, but stable emulsion particles are obtained unless an emulsifying and dispersing device with high shearing force is used. There was a disadvantage that you couldn't. Therefore, it has been desired to develop an emulsifying composition which gives silicone emulsion particles excellent in usability and storage stability, and an oil-in-water type silicone emulsion composition using the same. The present invention has been made in order to meet the above-mentioned demands, and an object thereof is to provide an oil-in-water type silicone emulsion composition which is excellent in usability and has a small particle size and is stable even after long-term storage. .
