Nonylphenol ethoxylate (NPE), chemically referred to as polyethylene glycol mono-4-nonylphenyl ether (C₁₅H₂₄O(C₂H₄O)ₙ), is a nonionic surfactant widely employed in industrial and domestic cleaning agents, agrochemicals, coatings, textiles, and personal care products owing to its outstanding detergency, wetting, and emulsification capabilities. It is synthesized through the polymerization of nonylphenol with ethylene oxide, resulting in a viscous pale yellow to brown liquid with a characteristic odor. Despite its functional effectiveness in cleaning and emulsification, NPE is associated with significant environmental concerns—including aquatic toxicity and slow biodegradation—which have prompted strict regulatory limitations on its application in many regions.

Nonylphenol Ethoxylates (NPEs) are a class of nonionic surfactants typically supplied in liquid form. Commercial variants are categorized according to the number of ethylene oxide (EO) units incorporated into their molecular structure. These compounds perform diverse roles, functioning as adjuvants, detergents, cleaning agents, dispersants, emulsifiers, humectants, solubilizers, and wetting agents. NPEs see broad application across multiple sectors such as coatings, agricultural formulations, functional fluids, household and industrial cleaning, institutional maintenance, and oil and gas operations.
