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 ...

Critical Micelle Concentrations in Surfactant Mixtures and Blends by Simulation [PDF]

The Journal of Physical Chemistry B, 2021
We explore the use of coarse-grained dissipative particle dynamics simulations to predict critical micelle concentrations (CMCs) in polydisperse surfactant mixtures and blends. By fitting pseudo-phase separation models (PSMs) to aqueous solutions of binary surfactant mixtures at selected compositions above the CMC, we avoid the need for expensive ...
