Some Factors Affecting the Droplet Size and Charge of Dilute Oil-in-Water Emulsions Prepared by Self-Emulsification

The equilibrium particle size and zeta potential of emulsions prepared by self-emulsification of various hydrocarbon oils in water with mixtures of surfactants have been measured under different environmental conditions. Both factors were observed to be influenced by the nature and concentration of the surfactant mixtures, the type of hydrocarbon oil and the presence of electrolytes.
