Laboratory Rheo-SAXS Studies of Non-ionic Surfactants

Non-ionic surfactants are widely applied in the form of cleaning agents or detergents. Here we report on a combined rheological-scattering (Rheo-SAXS) study of an ethoxylate surfactant in water system. Measurements were performed using the SAXSpoint 5.0 laboratory SAXS/WAXS beamline with the unique and fully integrated Rheo-SAXS module. The obtained results prove a transition from lamellar to onion-like structures with increasing shear rate.
