1. Surfactant

   Surfactants 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. Surfactants may function as emulsifiers, wetting agents, detergents, foaming agents, or dispersants. The word "surfactant" is a blend of surface-active agent, coined c.  1950.Agents that increase surface tension are "surface active" in the literal sense but are not called surfactants as their effect is opposite to the common meaning. A common example of surface tension increase is salting out: by adding an inorganic salt to an aqueous solution of a weakly polar substance, the substance will precipitate. The substance may itself be a surfactant – this is one of the reasons why many surfactants are ineffective in sea water.

1. surfactant

   A surfactant is a substance that reduces the surface tension between two substances, such as oil and water, making them mix together more easily. It is often used in detergents and cleaning products. The term "surfactant" comes from the words "surface active agent."

Examples of surfactant in a Sentence

1. Marc Moss:

   Im not going to say the alveoli are normal and the surfactant is normal, but when someone has hypoxia out of proportion to what you would see in the lung, that makes lung specialists think there is a problem on the blood vessel side.
