Determine Formulation
¡Ü Water phase : water + surfactant
¡Ü Oil phase : water immiscible solvent + polymer + other ingredients (such as actives,
                       
          contrast agents, etc)
Factors to be considered
¡Ü Water miscibility
¡Ü Boiling points
¡Ü Toxicity
¡Ü Active Pharmaceutical ingredients (APIs)
¡Ü Diagnostic ingredients (such as contrast enhancers)
¡Ü Other ingredients (such as para-magnetic particles, metal oxides, etc.)
Determine Process
¡Ü Add oil to the water phase
¡Ü Mix using a rotor-stator motor to create a stable pre-mix
