Which of the following best defines 'emulsion'?

• A. A solid mixture of two oils
• B. A fine dispersion of liquid droplets in another liquid
• C. A gaseous mixture of oil and water
• D. An oily cream for skin treatment

Answer: (B)

The correct definition of 'emulsion' is a fine dispersion of liquid droplets in another liquid. Emulsions are mixtures of two immiscible liquids, commonly oil and water, where one liquid is dispersed in the form of small droplets throughout the other. This phenomenon typically requires an emulsifying agent to stabilize the mixture and prevent the droplets from coalescing. Understanding emulsions is essential in various fields, including food science, cosmetics, and pharmaceuticals, as they play a crucial role in the formulation of several products such as dressings, lotions, and creams. The stability and characteristics of an emulsion can vary based on the type of liquids used and the emulsifying agents employed. The other options do not accurately describe an emulsion; a solid mixture of oils suggests a different kind of mixture altogether, while a gaseous mixture does not pertain to emulsions, and an oily cream is just one possible application of an emulsion rather than a definition.
