An antifoaming agent, also known as a defoamer, is a chemical compound that prevents the formation of foam during industrial or chemical processes. There are many synonyms for antifoaming agents, including foam control agents, defoaming agents, foam suppressants, and anti-bubbling agents. These compounds are commonly used in the production of foods, beverages, pharmaceuticals, and polymers to eliminate or decrease foam production during fabrications. They can be composed of silicone, vegetable oils, mineral oils, and fatty acids, among other substances. In practical applications, antifoaming agents are necessary to avoid overflowing or contamination as a result of excessive foam formation.
