Versatile Industrial Applications – NPE is widely used across multiple sectors, including pesticides, textiles, cleaning agents, and cosmetic formulations, due to its adaptable chemical properties.
Stable and Functional Formulation – As a pale yellow to brown viscous liquid, NPE can be easily incorporated into various formulations, maintaining effectiveness under a range of processing conditions.
Products Description of Nonylphenol Ethoxylate CAS#9016-45-9
Nonylphenol ethoxylate (NPE), also known as polyethylene glycol mono-4-nonylphenyl ether (C15H24O(C2H4O)n), is a nonionic surfactant extensively used in industrial and household cleaning agents, pesticides, paints, textiles, and cosmetics due to its outstanding detergency, wetting, and emulsifying capabilities. It is a pale yellow to brown viscous liquid with a characteristic odor, produced through the polymerization of nonylphenol and ethylene oxide. While highly effective, its use is subject to regulatory limitations because of environmental concerns, particularly its aquatic toxicity and limited biodegradability.
