PROBLEM TO BE SOLVED: To provide a skin cleanser composition which provides a moist feeling after using and has a small viscosity change due to temperature without providing a slimy feeling at the time of use.SOLUTION: There is provided a skin cleanser composition in which a ratio of a component (a) is 0.01 to 5 mass%, a ratio of a component (b) is 5 to 30 mass%, a ratio of a component (c) is 1.0 to 20 mass%, (b)/(c) is 1/2 to 20/1, the total ratio of the component (a), the component (b) and the component (c) is 10 to 50 mass% and the remainder is water. (a) a compound represented by the following formula (1) (b) an alkali metal salt, an ammonium salt or an organic ammonium salt of a fatty acid having 8 to 22 carbon atoms (c) an acylamino acid-based anionic surfactant.COPYRIGHT: (C)2015,JPO&INPIT【課題】使用時にぬめり感を与えず、使用後にしっとり感が得られ、温度による粘度変化が小さい皮膚洗浄剤組成物を提供する。【解決手段】成分(a)の比率が0.01~5質量%、成分(b)の比率が5~30質量%、成分(c)の比率が1.0~20質量%であり、(b)/(c)が1/2~20/1であり、成分(a)、成分(b)および成分(c)の合計比率が10~50質量%であり、残部が水である。(a) 下記式(1)で示される化合物: (b) 炭素数が8~22である脂肪酸のアルカリ金属塩、アンモニウム塩または有機アンモニウム塩: (c) アシルアミノ酸系陰イオン性界面活性剤【化1】【選択図】 なし
