PROBLEM TO BE SOLVED: To provide an oil-in-water emulsion composition that has high moisture retention but has no stickiness, and has excellent emulsion stability even when containing a liquid oily agent, and provide a skin external preparation.SOLUTION: An oil-in-water emulsion composition contains (a) glycerol, (b) fatty acid salt, (c) liquid oil, (d) ethanol, (e) higher alcohol and (f) water. The content of (a) glycerol is 30-50 mass% relative to the total amount of the oil-in-water emulsion composition. The oil-in-water emulsion composition has an average emulsified particle diameter of 30-200 nm and a viscosity of 3,000-50,000 mPa s.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】高い保湿性を有しながらべたつき感がなく、液状油性薬剤を配合しても乳化安定性に優れた水中油型乳化組成物および皮膚外用剤を提供する。【解決手段】水中油型乳化組成物を、(a)グリセリン、(b)脂肪酸塩、(c)液状油分、(d)エタノール、(e)高級アルコールおよび(f)水を含む水中油型乳化組成物であって、(a)グリセリンの含有量が水中油型乳化組成物全量に対して30~50質量%であり、水中油型乳化組成物の平均乳化粒子径を30~200nm、粘度を3,000~50,000mPa・sとする。【選択図】なし
