An emulsion is a colloidal system consisting of two or more immiscible liquids in which one liquid is dispersed as fine droplets throughout the other. This type of dispersion requires a stabilizing agent, typically an emulsifier, to reduce the interfacial tension between the two fluids and prevent the separated components from rapidly recombining. The resulting structure is a suspension, yet it remains colloidally stable due to the surface chemistry provided by the emulsifying agents. Emulsions are widely encountered in nature and are utilized in various technological applications, including the formulation of paints, cosmetics, and certain pharmaceutical preparations.
