Dynamics of microphase separation of an oil-water-surfactant system is investigated by means of cell dynamical system approach on the basis of the proposed two-order-parameter time dependent Ginzburg-Landau model. For equal volumes of oil and water, the time evolution of characteristic length scale of domains is investigated by changing the average surfactant concentration. The more the amount of surfactant, the slower the dynamics. The results are analyzed by using the crossover scaling assumption.
