What characterizes an emulsion?

An emulsion is characterized by the presence of two immiscible liquids, meaning they do not naturally mix, where one liquid is dispersed in the other. Common examples of emulsions are oil and water mixtures, where tiny droplets of oil are suspended within the water phase. Emulsions are stabilized by emulsifiers, which are substances that help reduce the surface tension between the two liquids, allowing them to blend together more effectively.

This characteristic of emulsions is important in various beauty and skincare formulations, as it allows for the incorporation of both oil and water-soluble ingredients. This versatility is crucial for creating creams, lotions, and other products that aim to provide moisturizing benefits while delivering active ingredients efficiently to the skin. Understanding how emulsions work can greatly enhance the effectiveness and texture of cosmetic products.
