The surface chemical properties, water solubility and synergy were studied on the mixed systems based on OMDAB and sodium dodecyl sulfate(SDS), OMDAB and dodecylbenzenesulfonate acid sodium (LAS), OMDAB and betaine.The results showed that mixed solution is stable, and surface chemical properties remarkably enhanced in a certain range of concentration. Determined by the application of the complex system performance, complex system, part of the application performance than a single system, different degrees of increase, which was the role of synergistic effects.
