Nonylphenol (NP) is a well-known endocrine-disrupting chemical (EDC), which can enhance the progression of cancer by functioning as an estrogen‑like factor. In the present study, the effects of different concentrations of NP on COLO205 colorectal cancer (CRC) cells were examined.
biodegradation in these systems does not occur. (Page 25). Application of contaminated sludge to agricultural land needs further assessment(1).

Consumers can avoid products with NP/NPEs by looking for products with EPA’s Safer Choice Label on the shelves of major retailers. When you see the safer product label on a product it means that EPA scientists have evaluated every ingredient in the product to ensure it meets stringent human health and environmental criteria. Nonylphenol ethoxylates are degraded to nonylphenols, which are considered to be endocrine disrupters. What does the legislation say?
Under normal conditions, each round of mitosis should result in two identical daughter cells.
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.
AlkylPhenols (APs), by-products of microbial degradation of AlkylPhenol Polyethoxylates (APEOs), constitute an important class of Endocrine Disrupting Chemicals (EDCs), the two most often used environmental APs being 4-nonylphenol (4-NP) and 4-tert-octylphenol (4-t-OP). 2013-02-07 Nonylphenol (NP) has been suspected as an endocrine‐disrupting chemical. Japanese polyvinyl chloride (PVC) stretch films contained 0.5–3.3 mg/g of NP and 100–400 mg/g of plasticizers such as diisononyl adipate (DINA), di‐n‐alkyl adipate (DAA), and diacetyllauroyl glycerol (DALG).Migration of NP and plasticizers from PVC stretch films into food simulants (water; 4% acetic acid; 20% Consequentially, nonylphenol has greater solubility in the matrix with more alkaline character, because in this pH condition, nonylphenol presents greater ionic character, thereby increasing its water affinity.

water temperature does not become too cold for biological degradation. However, this does point out the need for good industrial That these surfactants contain NPE is a cause for concern, since the raw material used to make NPE,. 7 May 2019 Nonylphenol (NP) is one of the most worrisome and ubiquitous Several contaminants can be present in soil, such as pesticides, polycyclic aromatic mechanisms to counteract the stress induced by these toxicants.

D. … 2000-03-01 2011-09-14 Samples were analyzed for the following known and suspected EDCs: five phthalates, bisphenol A (BPA), triclosan, 4-nonylphenol (NP), and tris(2-chloroethyl) phosphate (TCEP), using well 2006-09-01 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.

Nonylphenol can be naturally produced via degradation of alkylphenol ethoxylates. Other than that, we can produce this compound in industrial-scale via alkylation of phenol with a mixture of nonenes in the presence of an acid catalyst.
What can government and industry do? The state of California has begun to address APEs by proposing nonylphenol ethoxylates in laundry detergent as a priority alkylphenol ethoxylates. On 1 April 2016, the following sum limit values will come into effect for all certification processes for nonylphenol (NP), octylphenol (OP), REACH RegulationNonylphenols and nonylphenol ethoxylates are included in the in concentrations equal to or greater than 0,1 % by weight for the following to nonylphenol ethoxylates present in textile articles which can reasonably In these cases if there is a link to a REACH registered substance factsheet then the substance IS registered. The correct total tonnage band can In these cases if there is a link to a REACH registered substance factsheet then the substance IS registered.
When you see the safer product label on a product it means that EPA scientists have evaluated every ingredient in the product to ensure it meets stringent human health and environmental criteria. Nonylphenol ethoxylates are degraded to nonylphenols, which are considered to be endocrine disrupters. What does the legislation say? According to REACH, NP and NPE shall not be placed on the market, or used, as substances or in mixtures in concentrations equal to or greater than 0,1% by weight for the following purposes: The can manufacturers changed their coating material to the low bisphenol A resin or PET films and voluntarily regulate its migration limit to under 5 or 10 ng/ml. Nonylphenol was found in most PVC wrapping films and gloves. It was generated from an oxidant, tris (nonylphenyl) phosphite.
