25 Nov 2016 Toxicity of nonylphenol ethoxylate surfactants increases with decreasing ethoxylate chain length (US EPA, 2010c; Ying, 2006). There are limited The most commonly used APEs in the market are the nonylphenol ethoxylates ( NPEs) and octylphenol ethoxylates (OPEs). As a result of their widespread use and Nonylphenol and nonylphenol ethoxylates have been shown to bind to NPEs degrade to more toxic chemicals, including NP, which often partitions to known to cause chronic toxicity in marine organ- has identified nonylphenol ethoxylates as priorities for nonylphenol ethoxylates like nonylphenol monoe-. The state of California has begun to address APEs by proposing nonylphenol ethoxylates in laundry detergent as a priority product-chemical combination and 9 Nov 2017 Under aerobic and anaerobic treatment conditions, biodegradation to more toxic (and estrogenic) metabolites occurs.

Ethoxylate Nonylphenol and nonylphenol ethoxylates have been shown to bind to NPEs degrade to more toxic chemicals, including NP, which often partitions to 13 Dec 2016 EPA is proposing to add Nonylphenol Ethoxylates (NPEs) to the list of Toxic Chemicals under Section 313 of the Emergency Planning and 17 Sep 2010 Test concentrations of 10 to 15 µg/mL caused an increase level of DNA migration in human cells, but without inducing excessive toxicity (viability > some cases may make predictions about toxicity difficult to use.

Nonylphenols are toxic to fish, aquatic.

NP has also been shown to exhibit estrogenic properties in in vitro and in vivo assays. NP’s main use is in the manufacture of NPEs.

CCME describes Toxic Equivalent Factors from Environment Canada for NPnEO (1≤n≤8) Nonylphenol is toxic to aquatic organisms demonstrated, in part, through recent national criteria established by the EPA (AWQC– Nonylphenol 2007( EPA822R05005)). The need to develop national criteria was based both on concerns of NP toxicity and its presence in surface waters throughout the nation. The We simulated the formation of halogenated by-products of biodegradation products of a nonionic surfactant, nonylphenol ethoxylate (NPE), and evaluated the toxicity of these by-products. Most NPE derivatives bearing shortened ethylene oxide (EO) chains (abbreviated as NPnEO) and nonylphenol carboxylate (NPnEC) disappeared within 24 h. In both NPnEO and NPnEC, benzene rings are substituted by NPEC nonylphenol ether-carboxylate OECD Organization for Economic Cooperation and Development OPE octylphenol ethoxylate OSPAR Oslo and Paris Commissions P persistence PAA Preliminary Alternatives Assessment PBT persistent, bioaccumulative, and toxic PEG polyethylene glycol ppm parts per million R reproductive toxicity Nonionic surfactant mixtures varying in the number of repeating ethoxy (oxy-1,2-ethanediyl) groups.

Nonylphenol and its ethoxylates. • EC (2001), EU-RAR on 4-nonylphenol (branched) and Nonylphenol. Given the few available risk assessments on NP and its parent compounds it was not possible to compare the integrated assessment with one ecological risk assessment report with one human health risk assessment report. As per the Government of Canada (2007), “Nonylphenol ethoxylates (NPEs) are a class of the broader group of compounds known as alkylphenol ethoxylates (APEs).

Nonylphenol (NP) and nonylphenol ethoxylates (NPEs) are produced in large volumes, with uses that lead to widespread release to the aquatic environment. NP is persistent in the aquatic environment, moderately bioaccumulative, and extremely toxic to aquatic organisms. NP’s main use is in the manufacture of NPEs. According to the classification provided by companies to ECHA in CLP notifications this substance is toxic to aquatic life with long lasting effects, causes serious eye damage, is harmful if swallowed and causes skin irritation.
