n: a material that causes water and oil to form an emulsion. Water normally occurs separately from oil;if, however, an emulsifying agent is present, the water becomes dispersed in the oil as tiny droplets. Or, rarely, the oil may be dispersed in the water. In either case, the emulsion must be treated to separate the water and the oil.
