ABSTRACT
Surfactant systems can self-assemble into various structures that show a rich variety of rheological properties [1]. Newtonian and non-Newtonian behavior can occur even in the micellar region, and the viscosity (h) of highly dilute aqueous

solutions of spherical micelles increases with the volume fraction of the globular aggregates (jm) according to Einstein’s equation
CMC m(1 2.5 )= +h h j (7.1)
where hCMC is the Newtonian continuous phase viscosity at the critical micellar concentration. This equation does not include interactions, however, and is strictly limited to the low-concentration regime.
