I.Definition The emulsion is a colloidal system with a particle size of 0.1~10μm formed by two insoluble liquids through the action of emulsifier. Secondary dispersion refers to a colloidal system formed by particles (or molecular groups) less than 1μm are dispersed into a continuous phase (such as water) under the action of a stabilizer. By definition, the formation of emulsions and secondary dis...
