n: The material that decreases the surface tension of water, solution and suspension liquid and decreases or eliminates froth.

n: salt of stearic acid that is a saturated, 18-carbon fatty acid. Certain compounds, such as aluminum stearate, calcium stearate, and zinc stearate, are used in drilling fluids as defoamers or lubricants. Stearates can also be used as surfactants in air drilling to prevent small quantities of water from creating mud that could clog the hole.

n: a soluble compound that concentrates on the surface boundary between two substances such as oil and water and reduces the surface tension between the substances. The use of surfactants permits the thorough surface contact or mixing of substances that ordinarily remain separate. Surfactants are used in the petroleum industry as additives to drilling mud and to water during chemical flooding. See micellar- polymer flooding, surfactant mud.

n: A chemical that acts as a surface active agent. This term encompasses a multitude of materials that function as emulsifiers, dispersants, oil-wetters, water-wetters, foamers and defoamers. The type of surfactant behavior, whether acting as an emulsifier o

a chemical that is attracted to the surface of a fluid and modifies the properties such as surface tension.
