PROBLEM TO BE SOLVED: To provide a method of producing a surfactant composition that has low stringing properties, wherein the stringing is prevented which is more likely to occur in the surfactant composition that contains a cationic polymer.SOLUTION: The surfactant composition contains an anion surfactant (a), an ampholytic surfactant (b), a polymer (c) having a cationic group, and water. The method of producing the surfactant composition includes: a step (1) of mixing the component (a) with the component (b) to obtain a surfactant mixture a step (2) of mixing the component (c) with the water to obtain 5 mass% or lower of a polymer dispersion and a step (3) of mixing the surfactant mixture with the polymer dispersion.COPYRIGHT: (C)2012,JPO&INPIT【課題】カチオン性高分子を含有する界面活性剤組成物において生じやすい糸曳きが抑制された(曳糸性の低い)界面活性剤組成物の製造方法を提供すること。【解決手段】陰イオン界面活性剤(a)と、両性界面活性剤(b)と、カチオン基を有する高分子(c)と、水とを含有する界面活性剤組成物の製造方法において、前記(a)成分と前記(b)成分と水とを混合して界面活性剤混合物を得る工程(1)と、前記(c)成分と水とを混合して5質量%以下の高分子分散液を得る工程(2)と、前記界面活性剤混合物と前記高分子分散液とを混合する工程(3)とを有する、界面活性剤組成物の製造方法。【選択図】なし
