In a water-in-oil emulsion, which is the external phase?

Explanation:
Emulsions are classified by which phase is continuous around the droplets. In a water-in-oil emulsion, the water droplets are dispersed within a continuous oil phase. That continuous oil forms the external environment surrounding the droplets, so oil is the external (continuous) phase. If instead it were oil-in-water, the roles would swap and water would be the external phase.
