A Surfactant Concentration Model for the Systematic Determination of the Critical Micellar Concentration and the Transition Width

Molecules, 2021
The critical micellar concentration (cmc) is a fundamental property of surfactant solutions. Many proposed methods for the definition and determination of the cmc from property-concentration plots yield values, which depend on the studied property, on ...
