Water-based emulsions are mixtures where tiny droplets of oil are dispersed in water, creating a stable blend. These emulsions are commonly used in various products, including paints, cosmetics, and food items. The water acts as a continuous phase, while the oil droplets form the dispersed phase, allowing for a smooth texture and easy application. To stabilize these emulsions, emulsifiers are often added. Emulsifiers are substances that help keep the oil and water mixed by reducing the surface tension between the two. This property makes water-based emulsions versatile and popular in industries that require effective mixing of oil and water components.
