In this experimental study we give results concerning the shear thickening behavior exhibited by an aqueous cationic surfactant solution of CTAB in the presence of added NaTOS. We carefully investigate the rheological characteristics of this phenomenon corresponding to a shear induced state (SIS), the reproductibility and also the transient regimes. We show that with steady experiments there exist no hysteresis effect. Finally we give the evolution of the shear thickening characteristics against temperature.
