| 摘要 | Disclosed is an oil-in-water type emulsion composition which has excellent temporal and temperature stability and exerts a good feeling of use; and a method of producing the same. Emulsification is carried out through a specific intermediate phase formed by mixing a surfactant capable of forming an Lα phase, a surfactant capable of forming an H1 phase, and water. The intermediate phase preferably has an interfacial tension of 0.01 to 8 mN/m in terms of relative value with respect to polyperfluoromethylisopropyl ether. The oil-in-water type emulsion composition is produced by a production method that includes the step of sequentially adding an oil phase component and an aqueous phase component to the intermediate phase. | ||||||
