Surfactant - Wikipedia
WebSurfactants are chemical compounds that decrease the surface tension or interfacial tension between two liquids, a liquid and a gas, or a liquid and a solid. The word "surfactant" is a blend of surface-active agent, [1] coined c. 1950. [2]
Surfactant | Definition, Properties, Examples, & Facts
WebApr 4, 2024 · Surfactant, substance such as a detergent that, when added to a liquid, reduces its surface tension, thereby increasing its spreading and wetting properties. In the dyeing of textiles, surfactants help the dye penetrate the fabric evenly. Learn more about surfactants in this article.

WebJan 1, 2022 · A surfactant is a compound that reduces surface tension between two phases, such as two liquids, a liquid and gas, or even a liquid and solid. For example, adding detergent reduces surface tension in oily water, making it easier to remove soiling from fabrics or cookware.
Surfactant Definition and Examples - ThoughtCo
WebMar 31, 2019 · Surfactant is the word that combines the terms "surface active agent". Surfactants or tensides are chemical species that act as wetting agents to lower the surface tension of a liquid and allow for increased spreadability. This can be at a liquid-liquid interface or a liquid- gas interface.
