In which type of emulsion are water droplets dispersed?

Solid-in-water emulsion
Oil-in-water emulsion
Gas-in-water emulsion
Water-in-oil emulsion

The correct answer is: Water-in-oil emulsion

In a water-in-oil emulsion, water droplets are dispersed within the oil phase. This means that the water is the dispersed phase and the oil is the continuous phase. This type of emulsion is commonly used in products like cold creams and ointments where a barrier is needed to prevent moisture loss from the skin. This emulsion provides a protective layer on the skin surface, making it beneficial for dry or sensitive skin types. Solid-in-water emulsions involve solid particles dispersed in a continuous water phase and are not relevant to the dispersion of water droplets. Oil-in-water emulsions have oil droplets dispersed in a continuous water phase, which is opposite to the scenario presented in the question. Gas-in-water emulsions consist of gas bubbles dispersed in a continuous water phase and are not the type of emulsion where water droplets are dispersed.
