EC number: 500-024-6 | CAS number: 9016-45-9 . H411: Toxic to aquatic life with long lasting effects. Precautionary statements tion of NPEs occurs through the loss of ethoxylate (EO) groups, resulting in compounds that are more toxic, estrogenic, and environmentally persistent than the parent compounds (Environment Canada 2000). Primary biodeg-radation of NPEs in aquatic systems is fast, but the resul-tant products, nonylphenol monoethoxylate (NP1EO), 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.
Concerns first emerged in 1983–84 when Giger and co-workers from Switzerland established that nonylphenol ethoxylates and products of degradation were more toxic to aquatic life than their precursors (Giger et al., 1984). Intergenerational toxicity of nonylphenol ethoxylate (NP-9) in Caenorhabditis elegans. De la Parra-Guerra A(1), Stürzenbaum S(2), Olivero-Verbel J(3). Author information: (1)Environmental and Computational Chemistry Group, University of Cartagena, Cartagena, Colombia. Nonyl-phenol ethoxylates have much narrower homologue distributions than alcohol ethoxylates (ICI datasheet for Synperonic NP surfactants). 880 million pounds (4 mio metric tonnes) of alkyl phenol ethoxylates are used annually throughout the world. 80-85% are sold as nonylphenol ethoxylate (NPE), over 15% as octylphenol ethoxylate, and 1% each as Toxicity studies on nonylphenol ethoxylates (isomers), such as NP-9, are less abundant than those based on NP. However, although this family of compounds has diverse derivatives, including short and long chain isomers, many of them display high estrogenicity, even greater than that observed for NP, sometimes several orders of magnitude higher Nonylphenol, ethoxylated.
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.
metabolites with potential endocrine disruption,. the 23 Jul 2013 Nonylphenol and its ethoxylates (NP and NPEs) have been used for more than 40 years as detergents, emulsifiers, wetting agents and dispersing 20 Jun 2018 The agency proposed to add short-chain NPEs to the EPCRA toxic chemical list because they are believed to be highly toxic to aquatic organisms 3 Jun 2014 The aim of this paper was to examine the sublethal toxic effects of nonylphenol ethoxylate (NP10EO), its primary degradation product 8 Jun 2018 EPA states that its assessment of long-chain NPEs “is that, depending on chain length, they are low to moderately toxic to aquatic organisms but However, since NP is unlikely to be present in the aquatic environment in the absence of other nonylphenol ethoxylate (NPE) degradation by-products, the toxicity, 27 Nov 2016 Nonylphenol Ethoxylates (NPE) are used in a wide variety of industrial applications and consumer products. NPEs, though less toxic than NP, Get the Facts: NPEs (nonylphenol ethoxylates) · Hormone (endocrine) disruption · Extreme aquatic toxicity · Skin and eye irritation · Reproductive harm · Birth defects Table 2.1 Estimated uses of nonylphenol ethoxylate surfactants (CES, 1993) NP and OP are persistent in the environment and are of much higher toxicity than 5 Jan 2017 Nonylphenol ethoxylate-6.

The list now includes a category containing 13 nonylphenol ethoxylates (NPE). Since they are highly persistent and hydrophobic, they accumulate mostly on sludge.In this study using Anaerobic Toxicity Assay (ATA) tests, the toxicity of a model nonylphenol compound, nonylphenol diethoxylate (NP2EO), for anaerobic digestion of sludge was determined.
Widely recognized for extreme aquatic toxicity to fish and wildlife, NPEs and NP may also threaten the health of the developing fetus and young children.

80-85% are sold as nonylphenol ethoxylate (NPE), over 15% as octylphenol ethoxylate, and 1% each as Toxic substances list: nonylphenol and its ethoxylates. Nonylphenol and its ethoxylates (NP and NPEs) have been used for more than 40 years as detergents, emulsifiers, wetting agents and dispersing agents. From data obtained by Environment Canada, an estimated 18,000 tonnes of NP and NPEs were used in Canada in 1998. 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.
Nonylphenol is highly toxic to aquatic organisms and has been found in natural waters. Because of nonylphenol's toxicity, chemical properties, and widespread use to make other chemicals, concerns have been raised over the potential risks to aquatic organisms from exposure to nonylphenol. 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
Nonylphenol ethoxylates (NPEs) are endocrine-disrupting chemicals that mimic estrogen and are linked to both hormonal problems and cancer.

NPEs (nonylphenol ethoxylates) break down in the environment into nonylphenol (NP), one of the most notorious examples of persistent, bioaccumulative and toxic chemicals (PBTs). Widely recognized for extreme aquatic toxicity to fish and wildlife, NPEs and NP may also threaten the health of the developing fetus and young children.

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.
