One of the first references to emulsions was recorded by Galen(131-c.201), the Greek physician. Beginning with that early referenceto the emulsifying power of beeswax, the art and science of emulsificationhas flourished.Emulsions are prepared and used for a variety of reasons. As oilpaint cannot be applied to a damp surface, it is emulsified in water.The oil paint, then, in the form of an emulsion, can be applied to a dampsurface. Therefore, the emulsion can change the application characteristicsof a material.Water is a desirable, cheap diluent, and an emulsion is an easymethod of using water to dilute materials that are not soluble in water.In addition, the fire hazard of flam
