The results of experimental studies of the effect of the addition of silicon oxide nanoparticles on the stability of inverse emulsions based on mineral oils are presented. The concentration of nanoparticles in the emulsion was varied from 0.25 to 2 wt%. The following ratios of the volume fractions of the hydrocarbon phase and water were investigated: 70/30, 80/20, 90/10. Several types of emulsifiers have been considered. It has been shown that, even at low concentrations, hydrophobic SiO2 nanoparticles significantly improve the stability of inverse emulsions. Destabilization rate of the emulsion upon addition of 2 wt%. of nanoparticles decreases 1.7 times.
