Emulsion - Emulsions Throughout History

Emulsions in one form or another, have been used for centuries. Early societies learned to take advantage of this natural phenomenon; for example, the ancient Egyptians used eggs, to emulsify berry extracts, with oils to form crude emulsified paints. In more recent times, emulsions have been developed to deliver medicine in the form of ointments. Today, many products including drugs, paints and inks, cosmetics, and even certain foods, are made possible through the use of emulsions.
