Nonylphenol Ethoxylates Nonylphenols are a family of closely related organic compounds called alkylphenols. They are used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers.[2] These compounds are also precursors to the commercially important non-ionic surfactants alkylphenol ethoxylates and nonylphenol ethoxylates, which are

In the usual application, alcohols and phenols are converted into R(OC 2 H 4) n OH where n ranges from 1 to 10. Such compounds are called alcohol ethoxylates. Alcohol ethoxylates are often converted to related Nonylphenol ethoxylates (NPE) are man-made compounds with the chemical formula (C 2 H 4 O) n C 15 H 24 O. They are compounds of nonylphenol [C 15 H 24 O] with one or more groups of ethoxylates [(C 2 H 4 O)n] attached. The number (n) of ethoxylate groups varies between NPE compounds, imparting different properties to the chemical substance. 51811-79-1 - Ethoxylated nonylphenol phosphate - Similar structures search, synonyms, formulas, resource links, and other chemical information.

September 25, 2014 – EPA proposed a Significant New Use Rule to require Agency review before a manufacturer starts or resumes use of 15 nonylphenols (NPs) and nonylphenol ethoxylates (NPEs). This SNUR, when finalized, will provide EPA the opportunity to review and evaluate any intended new or resumed uses of these chemicals and, if necessary, take action to limit those uses.
