The role of emulsifier in stabilization of emulsions containing colloidal alumina particles

► Rheological behaviour of water-in-oil and oil-in-water emulsions was studied. ► The emulsions were stabilized by both solid particles and non-ionic emulsifier. ► Dynamic rheological measurements were carried out in linear and non-linear regimes. ► The addition of emulsifier improved the stability, however, it did not significantly influence the emulsion flow behaviour. ► With addition of emulsifier, the elastic solid-like structure of emulsion can be changed into a viscous liquid-like structure.
