Preferred Label : critical micelle concentration;
IUPAC acronym : c.m.c.; cmc;
IUPAC definition : There is a relatively small range of concentrations separating the limit below which
virtually no micelle are detected and the limit above which virtually all additional
surfactant molecules form micelles. Many properties of surfactant solutions, if plotted
against the concentration, appear to change at a different rate above and below this
range. By extrapolating the loci of such a property above and below this range until
they intersect, a value may be obtained known as the critical micellization concentration
(critical micelle concentration), symbol cM, abbreviation cmc (or c.m.c.). As values
obtained using different properties are not quite identical, the method by which the
cmc is determined should be clearly stated.;
