We analyze in mean-field approximation the liquid–liquid interfacial properties of a micellar solution model designed to describe amphiphiles in polar solvents. Under specific conditions the amphiphile concentration profiles become non-monotonous and entail enhanced interfacial adsorption. We...

A prominent feature of the phase behavior of aqueous solutions of nonionic amphiphiles is a phase separation into dilute and concentrated micellar liquids above a lower critical solution temperature Tc. Experiment has revealed a strong asymmetry of the coexistence curve, a high sensitivity of...
