Abstract
The cationic CTAC and zwitterionic SPE 98330 surfactants were investigated and their rheological properties compared. Also the influence of solvent qu ality (the presence of ions, particularly Ca2+) on both the viscosity and e lasticity of surfactants were investigated. Differences in the storage modu lus, G ', are negligible but there are substantial differences in the loss modulus, G ". Shear induced state (SIS) was detected in all samples.
