An object of the present invention synthetic surfactant does not substantially contain , on excellent and hardly stability syneresis at that , even creamy cosmetic oil-in-water emulsion composition that combines the excellent feeling of such familiar ease , the and I provide a cosmetic . A water , the oil component , containing the alkali salts of fatty acids and fatty acid , viscosity is a creamy cosmetic oil-in-water emulsion composition of 2,000~90,000mPa s, the entire emulsion composition among the synthetic surfactants is not substantially free of include behenic acid , stearic acid and palmitic acid as fatty acids , is 3 to 15 % by weight total content of alkali salts of fatty acids and fatty acid , behenic in the fatty acid acid / weight ratio of stearic acid / palmitic acid is 13 to 68 / 17 to 57 / 15 to 50 , the weight ratio of behenic acid alkali salt / stearic acid alkali salt / palmitic acid alkali salts of the alkali salts of fatty acids is 13 is to 68 / 17-57 / 15-50 . [ Selection Figure Figure 4【課題】 合成界面活性剤を実質的に含有せず、その上で離水しにくく安定性に優れ、さらにはなじみやすさなどの優れた使用感を併せ持つクリーム状化粧料用水中油型乳化組成物、及び化粧料を提供する。【解決手段】 水、油性成分、脂肪酸及び脂肪酸のアルカリ塩を含有し、粘度が2,000~90,000mPa・sのクリーム状化粧料用水中油型乳化組成物であって、この乳化組成物全体中、合成界面活性剤を実質的に含有せず、脂肪酸としてベヘン酸、ステアリン酸及びパルミチン酸を含み、脂肪酸及び脂肪酸のアルカリ塩の合計含有量が3~15重量%であり、脂肪酸中のベヘン酸/ステアリン酸/パルミチン酸の重量比が13~68/17~57/15~50であり、脂肪酸のアルカリ塩中のベヘン酸アルカリ塩/ステアリン酸アルカリ塩/パルミチン酸アルカリ塩の重量比が13~68/17~57/15~50である。【選択図】 図4
