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.

The U.S. Environmental Protec- tion Agency (EPA) issued a Chemical Hazard Information Profile on NP and identified numerous environmental effect data gaps.6 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. The USA Environmental Protection Agency (EPA) released an assessment that looked for safe alternatives to NPE … lating to restrictions on the marketing and use of nonylphenol and nonylphenol ethoxylates for those uses, which have an impact on the aquatic environment. This 26th Amendment has been published in the Official Journal of the EU on 17 July 2003 and regulates in Annex 1 that nonylphenol and nonylphenol ethoxylates may not be placed on the mole number of ethylene oxide. There is a wide HLB range depend their molar ratios between nonylphenol and E.O. The common mole ratio forms for detergency are NPE 9 - 12, where the number indicates ethoxylate chain length. The lower number mole ratio products are used as wetting agent whereas the higher moles ratio products are 4-Nonylphenol, branched and linear, ethoxylated substances with a linear and/or branched alkyl chain with a carbon number of 9 covalently bound in position 4 to phenol, ethoxylated covering UVCB- and well-defined substances, polymers and homologues, which include any of the individual isomers and/or combinations thereof Tergitol(R) NP-10, Surfactant is a Nonylphenol Ethoxylate based surfactant. It is nonionic and provides excellent detergency, rinse-ability, and low odor.

An NPE is composed of a nonyl chain, usually branched, attached to a phenol ring (hydrophobe moiety) which is combined, via an ether linkage, with one or more ethylene oxide or polyoxyethylene units (hydrophile moiety). 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. Many products are non-alkyl phenol ethoxylate (APE) based, and readily biodegradable with low aquatic toxicity.

2 Volatilization of polyethyleneglycol nonylphenol ether from moist soil surfaces is not expected to be an important fate process(SRC) based on a range of Henry's Law constants from 2.45X10-9 atm-cu m/mole for nonylphenol (a measured value)(3) to 4.1X10-12 atm-cu m/mole for nonylphenol ethoxylate (n=6), developed using a fragment constant Nonylphenol ethoxylate structure where n = the average number of moles of ethylene oxide per mole of NP and ranges from 1 to 100.
