Author information: (1)Environmental and Computational Chemistry Group, University of Cartagena, Cartagena, Colombia. One of these environmental pollutants is nonylphenol ethoxylate (NP-9), also known as Tergitol, and its degradation product, nonylphenol (NP). The objective of this work was to determine the toxicity of NP and NP-9 in Caenorhabditis elegans. Wild-type L4 larvae were exposed to different concentrations of the surfactants to measure functional endpoints. Nonyl-phenol ethoxylates have much narrower homologue distributions than alcohol ethoxylates (ICI datasheet for Synperonic NP surfactants).

Nonylphenol, branched, ethoxylated - Substance Information

As per the Government of Canada (2007), “Nonylphenol ethoxylates (NPEs) are a class of the broader group of compounds known as alkylphenol ethoxylates (APEs). NPEs are high-volume chemicals that have been used for more than 40 years as detergents, emulsifiers, wetting agents and dispersing agents. Nonylphenol polyethoxylate-containing products are used in many sectors, including textile […] Nonylphenol and its ethoxylates (NP and NPEs) have been used for more than 40 years as detergents, emulsifiers, wetting agents and dispersing agents.

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. absence of other nonylphenol ethoxylate (NPE) degradation by-products, the toxicity, fate and behaviour of some of these (i.e.

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. Acute toxicity - oral Reason for no classification: data conclusive but not sufficient for classification Acute toxicity - dermal Reason for no classification: data lacking Acute toxicity - inhalation Reason for no classification: data lacking Skin corrosion / irritation Hazard category: Skin Irrit. 2 Hazard statement: H315: Causes skin irritation. Nonylphenol (NP) is the commercially most important member of the group of alkyl phenols. The term “nonylphenol” represents a large num-ber of isomeric compounds, varying in the point of attachment of the nonyl group to the phenol molecule, and in the degree of branching in the nonyl moiety.

Toxicity of Nonylphenol Ethoxylate Metabolites Many countries, large corporations and scientific entities have classified NPE metabolites as toxic.

The toxicity of NPEs to aquatic organisms increases as the length of the ethoxylate chain ventanamagica.site by: /06/26 · NPEs (nonylphenol ethoxylates) break down in the environment into nonylphenol (NP), one of the most notorious examples of persistent, bioaccumulative and toxic chemicals (PBTs). 2018-01-16 · products containing nonylphenol ethoxylates. As NPE clearly requires replacement, mainly due to the environmental toxicity of the primary degradate (nonylphenol, or NP), the objective of this AA is to identify an appropriate alternative chemical(s) as a substitute surfactant. ing mixtures (about 34,600 tons if calculated in terms of 100 % alkylphenol ethoxylate according to the survey by Japan Surfactant Industry Association). Of this production, about 85 % was ac-counted for by nonylphenol ethoxylates, and the remainder by octylphenol ethoxylates, etc.11) 4-nonylphenol (4-NP) is an estrogenic endocrine active chemical that is present in detergents and is known to contaminate food and drinking water.The aim of the present study was to evaluate whether 4-NP crosses the human placenta and if so, to what extent. Nonylphenol was found to induce vitellogenin at 20.3 (μg/L and completely inhibit testicular growth at 54.3 (μg/L. Octylphenol was found to induce vitellogenin at 4.8 (μg/L but did not affect gonadal size at concentrations up to 43.9 (μg/L (the highest concentration tested) when compared with controls.
