Lansurf AEP66 is a biodegradable nonionic surfactant produced through the reaction of ethylene oxide and propylene oxide on a synthetic primary fatty alcohol. It shares compatibility with soaps, anionic, cationic, and other nonionic surfactants, offering wetting, detergency, and low foam. Similar to AEP63, it is employed in cleaning applications where low foaming is essential, such as machine dishwash, metal cleaning, and bottle rinse formulations. It is also used in textiles, oils, lubricants, agrochemicals, paints, and polymers.
