Fatty acid based defoamers are a type of defoamer used in various industrial processes. These defoamers are made from fatty acid esters, typically long chain fatty acids, and are designed to break the surface tension of foam bubbles and reduce foaming. The fatty acid based defoamers are usually non-ionic and can be used in aqueous systems as well as many non-aqueous systems. They are compatible with many different surfactants and have good stability at a wide range of temperatures. They can be used in a variety of industries including metalworking, oil & gas, paper, and textile production.
