Emulsion vs. Solution — What's the Difference?
By Maham Liaqat & Fiza Rafique — Updated on May 4, 2024
Emulsion involves mixtures of two or more liquids that are normally immiscible, whereas a solution is a homogeneous mixture of two or more substances.

Key Differences
Emulsions are characterized by the combination of two liquids that do not normally mix, such as oil and water. In contrast, solutions are homogeneous mixtures where all components are uniformly distributed, like salt in water.
The stability of an emulsion often requires an emulsifying agent to prevent separation, whereas solutions are inherently stable due to the molecular interactions between the solute and solvent.
Emulsions can be classified into oil-in-water or water-in-oil, depending on the phase volumes and types of liquids involved. On the other hand, solutions do not have such classifications because they are completely uniform at the molecular level.
The appearance of emulsions is typically cloudy or opaque due to the scattering of light by the dispersed phase, while solutions are usually clear and transparent if the dissolved substances do not impart color.
In terms of uses, emulsions are commonly found in culinary applications, cosmetics, and pharmaceuticals because of their unique texture and delivery properties. Solutions, however, are ubiquitous in everyday life, in processes such as dissolving, cleaning, and chemical reactions.

Emulsion
An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) owing to liquid-liquid phase separation. Emulsions are part of a more general class of two-phase systems of matter called colloids.
