Complete saturation of the complexation capacity of cyclodextrins (CDs) is not required for micellization to take place. Investigation of the competition between micellization and complexation of surfactant monomers with β ‐CD (shown schematically) shows the presence of a high concentration of uncomplexed β ‐CD in equilibrium with the micellar system. This concentration increases with the length of the hydrocarbon chain of the surfactant.
