Emulsion

An emulsion is a mixture of two liquids that usually don't combine well, like oil and water. To create a stable emulsion, one liquid is dispersed into tiny droplets within the other, often with the help of an emulsifier, which is a substance that stabilizes the mixture. Common examples include mayonnaise and salad dressings, where oil is blended with vinegar or lemon juice. In these cases, the emulsifier helps keep the mixture from separating, ensuring a smooth and consistent texture. Emulsions are essential in cooking, cosmetics, and pharmaceuticals, serving various functions in different products.
