Nonionic surfactant, efficient foam control agent because of its low foam characteristics, inverse water solubility, high thermal and chemical stability, with good steric stabilization. Used in foam control processes such as fermentation of monosodium glutamate, lactic and citric acids; food processing; food washing; water treatment; and metal working products. Low surface tension makes it a particularly efficient rinse aid and low foam wetting agent in auto dish detergents, industrial and institutional cleaning, and in cleaning-place (CIP) applications such as food, dairy, and brewery cleaning. It can be used in oilfield drilling and production formulations. TERGITOL™ L-61 AOF is listed on CleanGredients™.
