What are the differences between emulsion and extract in terms of their composition and uses?

Emulsions are mixtures of two or more liquids that are usually immiscible, like oil and water, stabilized by an emulsifying agent. Extracts are concentrated solutions obtained by extracting the desired components from a substance, like herbs or plants, using a solvent. Emulsions are used in food products, cosmetics, and pharmaceuticals for their stability and texture, while extracts are commonly used in cooking, medicine, and skincare for their concentrated flavors or active ingredients.
