The present invention provides a production method that can easily produce an O/W emulsion composition without using a special cooling apparatus and be economical. The production method of an O/W emulsion composition comprising the preparation of an emulsified part that is an O/W emulsion by emulsifying and at a temperature of 70 C. or higher and an oil phase comprising (A) a mono-branched fatty acid POE (0-60) glycerin ester, (B) a linear higher alcohol having 16 or more carbon atoms capable to form an alpha-gel in water with said (A), and (C) an oil component and a part of an aqueous phase (a first aqueous phase) comprising (D) water and the cooling of this emulsified part by mixing with stirring the remaining main aqueous phase (a second aqueous phase) at 10 to 35 C., wherein an aqueous solvent in the emulsified part is 15 mass % or less.
