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) 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).

nonylphenol. Shorter ethoxylate chain alkylphenols have greater toxicity than longer ones. CCME describes Toxic Equivalent Factors from Environment Canada for NPnEO (1≤n≤8) and OPnEO(1≤n≤8) as half the relative toxicity of NP and OP. Certified nonylethoxylate and octylethoxylate standards greater than NP3EO and OP2EO

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. 2020-04-11 · Electronic address: joliverov@unicartagena.edu.co. The ethoxylated isomers of nonylphenol (NPEs, NP-9) are one of the main active ingredients present in nonionic surfactants employed as herbicides, cosmetics, paints, plastics, disinfectants and detergents.

their toxicity to the freshwater species Pimephales promelas (fathead minnow) and Ceriodaphnia dubia. Acute toxicity tests using nonylphenol (NP), nonylphenol monoethoxylate (NP1EO), and nonylphenol diethoxylate (NP2EO) were conducted using the single chemicals and as binary and tertiary mixtures. These compounds frequently

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. 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.

2008-10-01 · Nonylphenol is a toxic xenobiotic compound classified as an endocrine disrupter capable of interfering with the hormonal system of numerous organisms. It originates principally from the degradation of nonylphenol ethoxylates which are widely used as industrial surfactants. Alkylphenol ethoxylates and alkylphenols - update information on occurrence, fate and toxicity in aquatic environment. ence of nonylphenol ethoxylate surfactants and their pri- Nonylphenol (NP) (CAS number, 104-40-05) is a product of industrial synthesis formed during the alkylation process of phenols (ring structure in Figure 1). The addition of ethoxyl groups to the parent compound produces nonylphenol ethoxylates (NPE), which are used to produce industrial surfactants. Nonylphenol and short-chain nonylphenol ethoxylates such as NP 2 EO are present in aquatic environment as wastewater contaminants, and their toxic effects on aquatic species have been reported.

chemistry properties, toxicity and analytical methods in various matrices. As a degradation product of ethoxylated alkylphenols, nonylphenol presents a higher degree of reactivity than its precursor. Due to its harmful effects on the environment, use and production of nonylphenol has been banned in European Nonylphenol and its ethoxylates. • EC (2001), EU-RAR on 4-nonylphenol (branched) and Nonylphenol.

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.

With decreasing length of the ethoxylate chain, bioaccumulation and toxicity of APEs increases [10]. 2018-06-20 Alkylphenol ethoxylates and alkylphenols - update information on occurrence, fate and toxicity in aquatic environment. ence of nonylphenol ethoxylate surfactants and their pri- NP is persistent in the aquatic environment, moderately bioaccumulative, and extremely toxic to aquatic organisms.
