A coherent strand … WebFigure 3: Spherical micelles. The critical micelle concentration CMC is the surfactant concentration at and above which micelles are formed. It can be determined for surfactant solutions by measuring the surface tension at different concentrations. Below the CMC the surface tension decreases with increasing surfactant concentration as the ...

WebIn colloidal and surface chemistry, the critical micelle concentration ( CMC) is defined as the concentration of surfactants above which micelles form and all additional surfactants … WebThe micelles of the surfactant cause solubilization of the substrate, producing an isotropic solution of the chemical. The solubilizate can be incorporated in the surfactant micelle in different ways, depending on the nature of the substrate and the surfactant micelles.
WebThe CMC (critical micelle concentration) is the concentration of a surfactant in a bulk phase, above which aggregates of surfactant molecules, so-called micelles, start to form. The CMC is an important characteristic for surfactants.
