Physical Stability: It has already been noted that on purely thermodynamic grounds, emulsions are physically unstable. A reduction of the interfacial area by coalescence reduces the system’s energy, and this process is thermodynamically favoured. However, thermodynamic stability of emulsions differs […]
Theories of emulsification: Surfactant (Monomolecular adsorption): To reduce the interfacial tension Oil droplets are surrounded by a coherent monolayer of the surfactant which prevents coalescence. If the emulsifier is ionized, the presence of strong charge may lead to repulsion in […]
Emulsions are the mixtures of two or more type of liquids where, one is such as droplets, of tiny or even ultramicroscopic size, which are distributed throughout each other. These are usually formed from the component of liquids either in […]
