lémulsification
Lémulsification is the process of forming an emulsion by dispersing droplets of one liquid in another immiscible liquid, typically with the help of an emulsifying agent. The goal is to reduce interfacial tension and create a metastable mixture that remains dispersed long enough for its intended use. Mechanical energy—stirring, blending, homogenization—facilitates droplet breakup and distribution.
Emulsions are classified by the continuous phase: oil-in-water (O/W) or water-in-oil (W/O). Emulsifier selection and concentration,
Industrial and domestic production uses high-shear mixers, rotor-stator devices, high-pressure homogenizers, and ultrasonic devices to generate
Stability is challenged by creaming, coalescence, Ostwald ripening, and phase inversion. Emulsions are thermodynamically metastable; stabilization
