SLE3S-water system: a linear rheological characterisation

Abstract Surfactant-water mixtures display a complex rheological behaviour, with changes in parameters such as viscosity and moduli of several orders magnitude consequence phase changes, depending on their concentration temperature: this criticism heavily affects different industrial processes. In our work, linear behaviour aqueous commercial anionic surfactant, sodium lauryl ether sulphate, is investigated range temperature (30–60 °C) surfactant (20–72%wt) technological relevance. Four phases texture are identified by polarised light microscopy: micellar, hexagonal, cubic lamellar, all showing shear-thinning behaviour. Rheological show net jump relatively narrow range, suggesting temperature-induced change. The systematic analysis the widely used system, reported here for first time, can be fundamental support many applications. Graphical
