Nonylphenol Ethoxylate | 9016-45-9 - ChemicalBook
Dec 18, 2024 · Nonylphenol Ethoxylate, also known as NPEs, are nonionic surfactants that are liquid in form. Many different types of NPEs are determined by the number of moles of Ethylene Oxide, or EO. NPEs may function as adjuvants, cleaners, detergents, dispersants, emulsifiers, humectants, solubilizers or wetting agents.
