(3). Care shall be taken to keep up the homogeneity of emulsion by utilization of appropriate emulsifier and suspensions by usage of ideal stirrer in the course of filling. Mixing and filling procedures shall be specified and monitored.
Griffin devised a method for calculating well balanced mixtures of emulsifying brokers to deliver a selected variety of emulsion.

The consistency of emulsions varies greatly, starting from conveniently pourable liquids to semisolid creams.
