Methods of Emulsion Preparation

Commercially, emulsions are prepared in large volume mixing tanks and refined and stabilized by passage through a colloid mill or homogenizer. Extemporaneous production is more concerned with small scale methods. Several methods are generally available to the pharmacist. Each method requires that energy be put into the system in some form. The energy is supplied in a variety of ways: trituration, homogenization, agitation, and heat.
