Static and dynamic surface tension and interfacial rheological behavior of a novel anionic gemini-type surfactant without a spacer group, sodium 2,3-didodecyl-1,2,3,4-butane tetracarboxylate (GS), were investigated. Very low values for critical micelle concentration (8.9×10−5 M) as well as equilibrium surface tension (22.7 mN m −1 ) were observed for the aqueous solutions. Dynamic surface...
