n: a chemical with properties that cause the water droplets in a water-inoil emulsion to merge and settle out of the oil, or oil droplets in an oil-in-water emulsion to coalesce, when the chemical is added to the emulsion. Also called emulsion breaker. See demulsify, emulsion breaker.

a chemical additive, usually a surfactant, that helps break emulsions.

n: a combination of a demulsifier and solvent that is used during testing for the suspended S& W content of oil and during other operations.

n: a special chemical demulsifier that is often added to emulsion samples to determine the total amount of sediment and water in the samples. Also called knockout drops.

surfactants that exhibit an effect on water or oil by changing fluid properties at the interface of the fluid. May be emulsifiers, demulsifiers, surface tension lowering , flocculants, deflocculants, wetting agents, etc.
