Background

Emulsification is the effect of one liquid being dispersed uniformly as very fine droplets in another liquid that is immiscible with each other. Emulsification is a liquid-liquid interface phenomenon, in which two immiscible liquids, such as oil and water, are separated into two layers in a container, with less dense oil on the upper layer and more dense water on the lower layer. If a suitable surfactant is added, the oil is dispersed in water under vigorous stirring to form an emulsion.
