An equi-charged mixture of cationic gemini surfactant, C,C'-bis(sodium dodecyldimethylammonium bromide)-p-benzenedimethylene (12-Ph-12), and anionic surfactant, sodium laurate (SL), can be dissolved in cyclohexane to form reverse worm-like micelles. The samples, with their different surfactant concentrations and water contents, were studied using rheological measurements. The minimum value of W (0), the molar ratio of water to total surfactants, was 9 for the equally charged system of 12-Ph-12 (200 mmol L-1)/SL. The maximum value of zero-shear viscosity (eta (0)) of this system was 1858 Pa s(-1) at W (0) = 14. Upon increasing the 12-Ph-12 concentration to 300 mmol L-1, eta (0) increased rapidly to 2200 Pa s(-1). The dynamic rheology showed the typical visco-elastic response of a thread-like micelle solution at 12-Ph-12 (200 mmol L-1) and W (0) = 10, with a relaxation time (tau (R)) of 0.11 s. At W (0) = 14, a characteristic of a surfactant gel was shown, where the elastic modulus (G') and the viscous modulus (GaEuro(3)) were independent of frequency. Non-linear visco-elasticity showed a strain-softening response at high strains.
