In a water-in-oil emulsion, what is dispersed in what?

Oil droplets in water
Water droplets in oil
Oil molecules in air
Water molecules in gas

The correct answer is: Water droplets in oil

In a water-in-oil emulsion, water droplets are dispersed in oil. This means that small water droplets are suspended within the larger oil phase. This type of emulsion is commonly used in skincare products where it is desired to have a product with a richer, more occlusive texture, as the oil phase provides a barrier to prevent moisture loss from the skin. The other options are incorrect because they describe different types of dispersal phases that do not align with the concept of a water-in-oil emulsion.
