Emulsion - Emulsions Throughout History, Emulsions Are Created By Surfactants, Characteristics Of Emulsions, Uses Of Emulsions

An emulsion is a two phase system of immiscible liquids in which one liquid is dispersed in the other in the form of microscopic droplets. This dispersion is achieved through the use of emulsifying agents, known as surfactants, which act as chemical bridges between the two liquids. Emulsions provide a variety of benefits such as the ability to deliver water insoluble active materials from water based products, to improve control over a product's physical properties, and effectively dilute expensive or hazardous functional materials. These properties make emulsions useful in a variety of products including pharmaceuticals, cosmetics, paints and inks, pesticides, and foods.
