Semisolid preparations must be protected through proper packaging and storage from the destructive influences of air, light, moisture, and heat, and the possible chemical interactions between the preparation and the container
The physical properties of the dosage form depend on various factors, including the size of the dispersed particles, the interfacial tension between the phases, the partition coefficient of the active ingredient between the phases, and the product rheology.
In general, semisolid dosage forms are complex formulations having complex structural elements. They are often composed of two phases, one of which is a continuous (external) phase and the other a dispersed (internal) phase.
