Defoamer, also known as an anti-foaming agent, is a chemical additive that reduces and eliminates foam formation in liquids. Foam is formed when gas is trapped in a liquid, and it can cause problems in various industrial processes, such as in the production of food and beverages, pulp and paper, and wastewater treatment. Defoamers work by destabilizing foam bubbles and breaking them apart, allowing the gas to escape from the liquid. They typically contain surfactants or oils that spread over the surface of the liquid to disrupt foam formation. Defoamers are available in various forms, including liquid, powder, and emulsion, and are used in a wide range of industries to improve process efficiency and product quality
