critical micelle concentration

[′krid·ə·kəl mi′sel ‚kän·sən′trā·shən]
(physical chemistry)
The concentration of a micelle (oriented molecular arrangement of an electrically charged colloidal particle or ion) at which the rate of increase of electrical conductance with increase in concentration levels off or proceeds at a much slower rate.

The concentration, above which micelle formation becomes appreciable, is termed the critical micelle concentration (CMC).
It can be seen that, after the initial sharp decline in particle size, a quasi-equilibrium state is attained beyond a critical compatibilizer concentration called critical micelle concentration, CMC owing to micelle formation of the excess compatibilizer in one of the phases as well as the change in its molecular state at interface (5 wt% of compatibilizer in the present case).
The emulsion sample was diluted with an aqueous solution in which saturated styrene and surfactant with critical micelle concentration were present to avoid monomer or surfactant in the sample diffusing from droplets to aqueous phase.
p] stabilization, regarded as the critical micelle concentration (CMC), was reached in this case at about 0.
5 wt% montmorillonite a critical concentration is established analogous to the critical micelle concentration in surfactant sols.
The critical micelle concentration, [Mathematical Expression Omitted], was expressed as (10, 23, 24):
