Understanding Emulsion Formulation | Ascendia Pharmaceuticals
2021年11月8日 · An emulsion formulation is a liquid disperse system that uses small globules of a liquid (dispersed phase) distributed through another liquid in which it is immiscible. The dispersed phase is referred to as an internal or discontinuous phase, while the dispersion medium is the external or continuous phase.
