Surface properties and micellization behavior of Gemini sulfo-succinate sodium(GSS) and Triton X-100(TX-100) binary mixture in aqueous solution were investigated with various GSS spacer lengths.Compositions in mixture micelles and surface absorbance layer as well as interaction parameters between the two components were analyzed.Results showed that no obvious or maybe no presence of synergistic effect between GSS and TX-100 were found on surface property and micellization in aqueous solution

although TX-100 decreased apparently critical micelle concentration(cmc) of GSS and was major component in mixture micelles.GSS of shorter spacers was easier to form micelle itself and mixture micelle with TX-100.Spontaneous formation of mixture micelle and weak molecular interaction was observed in mixture of GSS362 and TX-100.
