In this paper, the effects of α, β-cyclodextrins (β-CD) on the critical micelle concentration (CMC) of CTAB, SDS, and Brij35 were investigated at 25°C using electrical conductivity and visible spectrophotometry. The results indicate that α, β-CD increase the CMC of the surfactants by the competitive inclusion of surfactant in cyclodextrin. From the experimental data, an empirical formula for CMC* (apparent critical micelle concentration) of these three surfactants was obtained.
