The critical micelle concentrations (CMCs) of a number of nonionic surfactants composed of fatty acids esterified to polyoxyethylene molecules containing large numbers of oxyethylene units ( E) were determined fluorimetrically using 8-anilino-1-naph-thalenesulfonate. These CMCs were found to be two...
