Formation of emulsion
WebThere are three theories of emulsification: surface tension theory, oriented wedge theory, and interfacial film theory. More than one theory can be applied to the same emulsion system. An emulsion is a dispersion in which the dispersed phase is made of minute globules of a liquid that are scattered across an immiscible medium. WebEmulsion Formation. Table 1 Maximum volume fraction before the dispersion of spheres will assume a more favorable packing or inverse. Full size table. The information in Table 1 of relevance for emulsion inversion is the random packing volumes, and the small difference between “random lose” and “random close” in the table is crucial ...
