Provided is a method for producing an O / W emulsion composition which can be easily produced without using a special cooling device and is excellent in economic efficiency. The method for producing an O / W emulsion composition of the present invention comprises (A) a nonionic surfactant and (B) a carbon number capable of forming an α gel in water together with the nonionic surfactant. Emulsified parts are prepared by emulsifying an oil phase containing 16 or more linear higher alcohols, (C) an oil component, and (D) a part of an aqueous phase containing water at a temperature of 70 ° C. or higher. While stirring the emulsified part, the remaining main aqueous phase at 10 to 35 ° C. is mixed with the emulsified part, and stirred until the oil phase is below the lower limit temperature of the temperature region in which the oil phase forms an α gel. Cooling is continued, and then stirring is stopped. [Selection figure] None |
