…Other classifications include chemical structure, synthesis method, application/performance, and raw materials, but from the perspective of synthetic chemistry, the following classification is generally used. Water-soluble surfactants are broadly divided into ionic and nonionic surfactants depending on the properties of the hydrophilic group that is the main component of their surface activity. The former are further divided into anionic and cationic surfactants depending on whether the hydrophilic group is anionic or cationic, and surfactants that contain both cationic and anionic structures in the molecule are called amphoteric surfactants. … *Some of the terminology that refers to "ionic surfactants" is listed below.

…そのほか,化学構造別,合成法別,用途・性能別,または原料別に分類されるが,合成化学の立場では次のように分類整理をするのが一般的である。 水溶性界面活性剤はその界面活性を示す主体である親水基の性質によりイオン界面活性剤と非イオン界面活性剤に大別される。前者はさらに親水基が陰イオンであるか陽イオンであるかにより陰イオン界面活性剤,陽イオン界面活性剤に区別され,分子内に陽イオン,陰イオン構造を同時に含むものを両性界面活性剤という。… ※「イオン界面活性剤」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
