Water-in-Oil Emulsions are mixtures where tiny droplets of water are dispersed in a continuous oil phase. This type of emulsion is commonly found in products like butter and certain cosmetics. The stability of these emulsions relies on emulsifiers, which are substances that help keep the water droplets suspended in the oil. These emulsions are characterized by their creamy texture and are often used in food and industrial applications. They can provide unique properties, such as improved flavor release in food products and enhanced moisture retention in skincare items. Proper formulation is essential for maintaining their stability and performance.
