The properties of a cationic slow-set emulsifier named INDULIN SBT in the absence and presence of Tween 40 and Tween 60 is investigated in this paper. After adding Tween 40 and Tween 60, the interfacial tension and dilatational modulus of SBT have remarkable changes. Compared with the pure SBT system, the interfacial properties of the mixed surfactant systems are improved obviously, especially if the ratio of the mixtures is 1 : 1. The Zeta potentials are also the lowest with favorable storage stability in these systems. At suitable ratios, synergistic adsorption may take place, resulting in remarkable enhanced interfacial properties. The combination of SBT and Tween 40 as well as Tween 60 could be used as surfactant mixtures applied in asphalt emulsions.
