When a defoamer does not perform as expected, the chemistry is not always the cause. Very often, it is the physical form that does not suit the application. A silicone defoamer comes in four distinct forms, which do not belong in the same places and are not dosed in the
“APGs are fine, but they foam far too much for machine applications.” This is a comment we still hear regularly, and one that deserves some nuance: it really depends on the chain length. Alkyl polyglucosides form a broader family than is often assumed, and the short cuts behave in the
Ethylene Oxide (EO) is a reactive organic compound that, when polymerized with fatty chains such as alcohols or amines, forms nonionic surfactants. These surfactants play a crucial role due to their ability to reduce surface tension between liquids or between a liquid and a solid, thus facilitating dispersion, emulsification, and
Surfactants: The Secrets of Industrial Performance Surfactants, also known as additives or sometimes “actives,” play a crucial role in a variety of products, from detergents to paints, and even in agrochemicals. Their use extends to cosmetics and pharmaceuticals, provided they meet quality standards. These products boast a range of properties
