It is process step of combining unblendable liquid phase in a formulation. It produces emulsions, with the help of homogenizers and rotor-stator mixers are particularly well suited for emulsifying. Its having an industrial application involving chemical processing, liquid pharmaceutical and food & beverage processing.
An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable). Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used interchangeably, emulsion should be used when both phases, dispersed and continuous, are liquids. In an emulsion, one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include vinaigrettes, milk, mayonnaise, and some cutting fluids for metal working.
