SURF - equilibrium interfacial properties

Equilibrium Interfacial Properties
Program SURF predicts either the air-water surface tension or the oil-water interfacial tension, as well as the surface concentration and composition, of aqueous solutions of surfactant mixtures comprising any number of surfactant components. The surfactants can be nonionic, ionic, or zwitterionic. A single experimental equilibrium surface or interfacial tension value is required for each surfactant component comprising the mixture.
