Description/Abstract The maximum additive concentration (MAC) of phenothiazine in aqueous micellar solutions of sodium dodecyl sulfate, manganese(II) dodecyl sulfate, and zinc(III) dodecyl sulfate was determined spectrophotometrically at 20, 25, and 30 C. The plots of MAC against surfactant concentrations could be divided into 2 straight lines.^The surfactant concentration at their intersection was in good agreement with the critical micelle concentration (CMC) determined by conventional methods.^The thermodynamic parameters of the interaction between monomeric phenothiazine molecule and micelle without any solubilizate were evaluated from the stepwise association equilibria between solubilizates and micelles.^Through the analysis of the data from the viewpoint of aggregation numbers and kinds of gegenions of micelles, it was determined that the aggregation numbers played a more important role than the gegenions for an incorporation of phenothiazine into the micelles.^The Poisson distribution is highly suggested for the distribution of phenothiazine among the present micelles.^21 references.
