Two-phase liquid system in which small droplets of one liquid (the internal phase) are immiscible
in and uniformly dispersed throughout a second continuous liquid phase (the external phase).
An emulsion in which the dispersed particles are a solid is called a
suspension; thus, a latex cannot be called an emulsion in the strictest sense. It should be noted
that the dispersed particles or globules are not soluble in the liquid, but remain discrete entities
dispersed throughout the liquid
