A Defoamer is a chemical additive that assists in reducing and prohibiting foam formation in an industrial process. They are used in a broad range of industries, finding purpose in the production of detergent, food, industrial processes and pharmaceuticals.

Usually, a Defoamer is considered an insoluble, with surface-active properties that retain a low viscosity, allowing it to quickly spread on foamy surfaces. It works by destabilising the foam through an affinity to the air-liquid surface. This results in splitting of the air bubbles and a breakdown of surface foam. Air bubbles that have been entrained are then agglomerated as the bigger bubbles rise to the surface of the bulk liquid at a more rapid rate.
