Critical micelle concentration and partition coefficient of mixed micelles: Analysis of ternary systems based on Markov chain model and simple mixture model

When two or more surfactants are mixed, the mixed system exhibits improved performance compared with a single surfactant in solution. The Markov chain model can analyze critical micelle concentration (CMC) of micelles, yielding results similar to those simple mixture model, which is typically referred as “regular solution theory”. In this study, hypotheses were tested: (1) for ternary systems be simplified by approximating association constant i and j Kij = Kji (2) quasi-simple that is, analogous helps interpret interaction parameter describe partition coefficient binary micelle. Equations derived assuming models experiment data, equations described data CMC well.
