The critical concentration, C, is defined as the concentration at which there is a change in the size distribution of the surfactant aggregates from a monotonically decreasing curve (below C), to one that possesses a maximum and a minimum above the critical concentration. The transition in shape occurs at a size distribution that displays an horizontal inflexion point. The critical micelle concentration (CMC) has a value close to the critical value C [3.1] and [3.2].
