Cleansing milk is classified as which type of mixture?

Cleansing milk is classified as an emulsion, which is a type of mixture formed by combining two immiscible liquids, typically oil and water, along with emulsifying agents that stabilize the mixture. In the case of cleansing milk, the primary function is to provide a gentle cleansing effect while retaining moisture on the skin. The emulsifying agents help blend the oils with water, resulting in a smooth texture that can effectively lift makeup and impurities without stripping the skin of its natural oils.

Emulsions are common in cosmetics and skincare products because they allow for a balance of hydration and cleansing properties. Other mixtures, like solutions, involve completely dissolved substances, whereas suspensions consist of solid particles dispersed throughout a liquid, which can settle over time. In contrast, emulsions remain stable due to the emulsifying agents, making cleansing milk a quintessential example of this type of mixture.
