In high pressure homogenization, the emulsion is forced through a small orifice under high pressure to create locally turbulent conditions that cause drop breakage. Because breakage of a mother drop into multiple daughter drops results in an increase in total surface area, the daughter drops must be stabilized by surfactant adsorption at the oil–water interface. The drop size distribution is strongly affected by the type and amount of surfactant in the emulsion formulation, as surfactants with rapid adsorption kinetics and favorable adsorption equilibria are most effective at reducing the interfacial tension and stabilizing newly formed droplets
