Emulsion — Chemistry Definition | AllChemicals | AllChemicals

What is Emulsion?

An emulsion is a colloid consisting of two immiscible liquid phases, typically oil and water, where one liquid is dispersed as fine droplets within the other. Emulsions are stabilised by emulsifying agents (surfactants) that reduce interfacial tension. Common examples include milk, mayonnaise, and photographic film. Emulsions are classified as oil-in-water (O/W) or water-in-oil (W/O).
