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.
