CCME describes Toxic Equivalent Factors from Environment Canada for NPnEO (1≤n≤8) These products are NP, nonylphenol ethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), nonylphenoxyacetic acid (NP1EC) and nonylphenoxyethoxyacetic acid (NP2EC). NPEs can be biodegraded through a mechanism of stepwise loss of ethoxy groups to form lower ethoxylated congeners, carboxylated products and NP. 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. 2007-06-24 Exact matches only.

4-nonylphenol polyethoxylates (4NPnEOs) are 4-nonylphenol isomers that exist in both branched and linear forms and contain an ethoxylated phenol ring with varying grades (chain lengths) of n ethoxylation. Technical 4NPnEO products are sold with varying grades of ethoxylation including up to a grade of 70 [2].

The nonyl group can be attached to the phenol ring at various locations, usually the 4- and, to lesser extent, the 2-positions, and can be either branched or linear.

NPE accounts for approximately 85% of alkylphenol eth-oxylate production (Anonymous 1997).

Nonylphenol Ethoxylates are nonionic surfactants produced by the process of ethoxylation on nonylphenol, which consist of phenol bearing a 9 carbon-tail.

alEcotoxicology and environmental safety, 175, undefined (2019-3-23) The widely used surfactant nonylphenol ethoxylate (NPEO) and its raw material 4-n-nonylphenol (4-n-NP), as well as its degradation products, are recognized as endocrine disrupting chemicals. Nonylphenol salts of Barium as well as calcium have application as heat stabilizers in plastic. Nonylphenol phosphate esters are used to retard flame. Nonylphenol is raw material for Nonlyphenol ethoxylate which is used in Surfactants.
