Fatty acid ethoxylate is a non-ionic surfactant. It is produced through a process called ethoxylation, where fatty acids are reacted with ethylene oxide to produce a mixture of hydrogen esters. These are used in a variety of household applications and cleaning applications. In cosmetics and pharmaceuticals, they are used as emulsifiers and solubilizers. The biggest application segment, however, is the household and personal care sector, which uses fatty acid ethoxylates in dishwashing, laundry, and metal cleaning products.
