 Water-in-water emulsion

A water-in-water (W/W) emulsion is a type of emulsion where two immiscible phases of water are combined. Unlike traditional emulsions, which might consist of oil droplets dispersed in a water phase (oil-in-water) or water droplets dispersed in an oil phase (water-in-oil), a water-in-water emulsion consists of one aqueous phase dispersed within another aqueous phase.
