Critical micelle concentration

Japanese: critical micelle concentration(英語表記)criticalmicelleconcentration
Critical micelle concentration

…When the concentration in a solution exceeds a certain level, several dozen molecules will combine to form micelles. This concentration is called the critical micelle concentration (CMC). Since 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. …

From [Misel]

…The existence of micelles was proposed in 1913 by James William McBain (1882-1953). When the concentration is low enough, surfactants dissolve in molecular form, but when they reach a certain concentration (critical micelle concentration, abbreviated as CMC), they form micelles, and the properties of the aqueous solution change significantly at this concentration. The inside of the micelles is lipophilic and can dissolve oils. …

…溶液中である濃度以上になると,数十個の分子が会合しミセルをつくる。この濃度を臨界ミセル濃度critical micelle concentration(略号CMC)という。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。…

【ミセル】より

…ミセルの存在は,1913年マクベーンJames William McBain(1882‐1953)により提唱された。濃度が十分低いとき,界面活性剤は分子状に溶解するが,ある濃度(臨界ミセル濃度critical micelle concentration,CMCと略記)になるとミセルを形成し,水溶液の性質はこの濃度を境にして顕著に変化する。ミセルの内部は親油性で,油類を溶かしこむことができる。…
