Definition of emulsion

emulsionnoun

nhũ tương

/ɪˈmʌlʃn//ɪˈmʌlʃn/

The word "emulsion" has its roots in Latin. The Latin word "emulsio" was derived from "emunde" meaning "to mingle with" and "lare" meaning "to break". The term was borrowed into Middle English in the 14th century, around the same time earliest forms of oil-based paints were developed. In the context of chemistry, an emulsion is a mixture of two or more liquids that don't normally mix, such as oil and water, where one liquid is dispersed within the other in the form of small droplets. This concept was crucial in understanding the properties of paints and coatings, which often rely on emulsions to achieve specific textures and finishes. The term "emulsion" has also been extended to describe similar phenomena in fields like food science, biology, and medicine, where it refers to a mixture of two or more liquids that don't mix, such as fat and water.
