…In non-polar solvents, surfactant molecules form an association with the polar groups facing inward and the hydrophobic groups facing outward. This is called a reverse micelle. Reverse micelles can solubilize water. … From [Misel]…When a surfactant is dissolved in a non-aqueous solvent such as benzene, it forms an association with the lipophilic groups facing outward and the hydrophilic groups facing inward. This is called a reverse micelle, and reverse micelles can solubilize water inside. The term micelle was coined in 1858 by Karl Wilhelm von Nägeli (1817-91), who believed that starch and cellulose gels exhibit optical anisotropy because they have a microcrystalline structure in which the molecules are oriented, and called this structure a micelle. … *Some of the terminology that refers to "reverse micelle" is listed below.

…非極性溶媒中では界面活性剤分子は極性基を内側に,疎水性基を外に向け会合する。これを逆ミセルという。逆ミセルは水を可溶化することができる。… 【ミセル】より…界面活性剤をベンゼンなどの非水溶媒に溶かすと,親油基を外に親水基を内に向けて会合する。これを逆ミセルといい,逆ミセルはその内部に水を可溶化することができる。ミセルという言葉は,1858年ネーゲリKarl Wilhelm von Nägeli(1817‐91)が,デンプンやセルロースのゲルが光学的異方性を示すのは,分子が配向した微結晶構造をもつためと考え,この構造をミセルと呼んだのが始まりである。… ※「逆ミセル」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 |
