Synergistic effect for lowering interfacial tension in alkyl benzene sulfonates mixtures-alkane systems was studied by spinning drop tensiometer. The results show that surfactant mixtures of similar structure tend to give the same min for the same nmin, while the alkane preference curve of the surfactant mixtures with different structures take on the shape of that of surfactant with higher interfacial activity. In the case of surfactant mixtures with different interfacial activities, the one with lower activity will modify the hydrophilic-lipophilic balance of surfactant with higher activity and result in synergism/antagonism.
