Emulsion inversion using solid particles

► We added hydrophilic solids at between 0.5 and 8 wt% in relation to the water. ► We determined the quantities necessary to invert the emulsions. ► Two hydrophilic solids were used: Aerosil® 200 and sodium bentonite. ► Rheological tests were performed, varying the temperature from 60 °C to 4 °C, with shear rates of 20-250 s−1. ► The viscosity reductions of up to three orders of magnitude were verified.
