…Because micelles have a size of colloidal dimensions, above the critical micelle concentration, the surfactant solution becomes a colloidal system and exhibits properties unique to colloids. At relatively low concentrations in water, surfactant molecules form spherical micelles with the hydrophobic parts facing inward and the hydrophilic parts facing outward, but at high concentrations they can assume various orientations. Micellar colloids can dissolve substances that are insoluble in water. … *Some of the terminology that refers to "spherical micelle" is listed below.

…ミセルはコロイド次元の大きさをもつので,臨界ミセル濃度以上で界面活性剤溶液はコロイド系となり,コロイドに特有の性質を示すようになる。水中で比較的低濃度では疎水性部分を内側に向け親水性部分を外に向けて界面活性剤分子が球状に会合した構造をもつ球形ミセルをつくるが,高濃度になるとさまざまな配向状態をとるようになる。ミセルコロイドは水に溶けない物質を溶解することができる。… ※「球形ミセル」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 |
