Q. What is an Emulsifier?
An emulsifier is a compound that contains both polar and nonpolar groups and thus is drawn to the interface between the two phases of an emulsion to coat the surface of the droplets. The nature of the emulsifier influences the type of emulsion that is formed. If it is attracted more strongly to water than to oil, the surface tension of water is reduced more than that of oil. The result is the formation of an oil-in-water emulsion.
