Abstract: Hydrodynamic cavitation, a newly developed process intensification technique, has demonstrated immense potential for intensifying diverse physical and chemical processes. In this study, hydrodynamic cavitation was explored as an efficient method for the formation of sub-100 nm oil-in-water (O/W) emulsions with high stability. O/W emulsion with an average droplet size of 27 nm was successfully prepared. The average droplet size of O/Wemulsions decreased with the increase of the inlet pressure, number of cavitation passes and surfactant concentration. The formed emulsion exhibited admirable physical stability during 8 months. Moreover, the hydrodynamic cavitationmethod can be generalized to fabricate large varieties of O/Wemulsions,which showed great potential for large-scale formation of O/Wemulsions with lower energy consumption.

Key words: Hydrodynamic cavitation, Emulsification, Emulsions, Droplet size, Size distribution
