The determination of the composition of mixed micellar systems is a major problem since only the composition ofthe total micellar solution is accessible to the experimenter. A new approach is introduced in the present work based on Equation Oriented Optimization and Margules asymmetric formulations whichisnot restricted to thenumber of components and guarantees the applicability ofthe Gibbs?Duhem relation. The method is validated through its application to systems from literature and the quality of the solutions is tested with already published data and by comparison with other approaches. We do also show how excess properties can be predicted and that the excess entropy is not zero as assumed by the original regular and sub-regular solution theories.
