PROBLEM TO BE SOLVED: To provide a method for producing a clay mineral-containing oil-in-water type emulsion composition having a good feeling of use in addition to stability such as stability with time and thermal stability.SOLUTION: There is provided a method for producing an oil-in-water type emulsion composition which comprises: a step 1 of mixing a composition comprising (A) a water-swellable clay mineral, (B) a surfactant containing 70 mass% or more of a polyglyceryl fatty acid ester and (C) water under heating at a temperature higher than a melting temperature of the polyglyceryl fatty acid ester in the component (B) to obtain a water phase; and a step 2 of mixing the water phase obtained in the step 1 and an oil phase containing (D) an oil agent to obtain an emulsified liquid, wherein the mass ratio [A/(A+B)] of the component (A) to the total amount of the component (A) and the component (B) in the water phase is 0.3 to 0.9.SELECTED DRAWING: None【課題】経日安定性、熱安定性等の安定性に加えて、使用感の良好な、粘土鉱物含有水中油型乳化組成物の製造方法の提供。【解決手段】 水中油型乳化組成物の製造方法であって、工程1:(A)水膨潤性粘土鉱物、(B)ポリグリセリン脂肪酸エステルを70質量%以上含む界面活性剤、及び(C)水を含む組成物を、成分(B)中のポリグリセリン脂肪酸エステルの融解温度以上の加熱下で混合して水相を得る工程工程2:工程1で得られた水相と(D)油剤を含む油相とを混合して乳化液を得る工程を有し、前記水相中の成分(A)と成分(B)との合計量に対する成分(A)の質量比[A/(A+B)]が0.3~0.9である水中油型乳化組成物の製造方法。【選択図】なし
