Cleansing milk is an example of what type of mixture?

Cleansing milk is classified as an emulsion, which is a mixture of two immiscible liquids (typically oil and water) that are combined with the help of an emulsifier. Emulsions are characterized by their ability to maintain a stable blend of these two phases, where one liquid is dispersed in the other. In the case of cleansing milk, the oil component helps to dissolve makeup and impurities, while the water component provides hydration and a refreshing feel on the skin.

Emulsions are commonly used in cosmetic formulations because they can effectively combine nourishing oils with water-based ingredients, allowing for smoother application and enhanced sensory experience. The stabilizing agents or emulsifiers prevent the two liquids from separating, making the product effective and practical for skincare routines.

In contrast, other mixture types such as solutions involve a solute completely dissolving in a solvent, resulting in a single-phase system, while suspensions consist of solid particles dispersed in a liquid but not dissolved, which can settle out over time. Colloids, on the other hand, are mixtures where tiny particles are dispersed throughout another substance, but they do not form distinct layers as seen in suspensions. Therefore, cleansing milk's characteristics align with those of an emulsion, affirming it as
