Due to interest in the exposure to bisphenol A in the community1 and the workplace, OSHA developed a validated method to collect and analyze bisphenol A and diglycidyl ether of bisphenol A. Excessive amounts of bisphenol A generate linear high molecular compounds with hydroxyl-, etherand epoxy-terminated groups. 2012 Jun 1;211(2):114-9. g) Doerge DR, Twaddle NC, Woodling KA, Fisher JW. These may be incorporated at low levels in vinyl ester resins to change their physical properties[45] and see common use in dental composites and sealants.[46][47]. Products made from BPA meet high-performance demands. FDAs Studies. People are generally exposed to minute levels of BPA, mostly from the ingestion of food or beverages that have been in contact with materials manufactured with BPA. Toxicol Sci. [2][7] BPA is produced on an industrial scale by the condensation of phenol and acetone, and has a global production scale which is expected to reach 10 million tonnes in 2022.[8]. [65][24], As a result of the presence of BPA in plastics and other commonplace materials, most people are frequently exposed to trace levels of BPA. #12-03 Keck Seng Tower, Toxicol Appl Pharmacol. What chemicals are in epoxy resin when you consider this? [37] Crystals form in the monoclinic space group P 21/n (where n indicates the glide plane); within this individual molecules of BPA are arraigned with a 91.5 torsion angle between the phenol rings. It is not a plasticizer,[11] although it is often wrongly labelled as such. Cured epoxy resins are inert materials used as protective liners in metal cans to maintain the quality of canned foods and beverages, and have achieved wide acceptance for use as protective coatings because of their exceptional combination of toughness, adhesion, formability, and chemical resistance. [23][24], Bisphenol A was first reported in 1891 by the Russian chemist Aleksandr Dianin. [66][67][68] The primary source of human exposure is via food, as epoxy and PVC are used to line the inside of food cans to prevent corrosion of the metal by acidic foodstuffs. Toxicol Lett. We provide Bisphenol A epoxy resin safety data sheet view and download for free at Echemi.com. [9][10] For epoxy resin, it is first converted to its diglycidyl ether (usually abbreviated BADGE or DGEBA). Bisphenol A (BPA) is a chemical building block that is used primarily to make polycarbonate plastics. Another reason for concern, especially for parents, may be because some animal studies report effects in fetuses and newborns exposed to BPA. [98], In all cases, wastewater treatment can be highly effective at removing BPA, giving reductions of 9198%. Epoxy resins made with BPA are tough and readily adhere to metal surfaces, making them excellent materials for protective coatings. Dianin in 1891. For example, FDA has participated with Health Canada in encouraging industry efforts to refine their manufacturing methods for the production of infant formula can linings to minimize migration of BPA into the formula. Uses of all substances that migrate from packaging into food, including BPA, are subject to premarket approval by FDA as indirect food additives or food contact substances. It was originally produced from coal tar and was named carbolic acid. Formula: CAS CAS: Chemical Abstract Service Registry Number . If youve ever read a news article or blog post about chemicals, you may have heard the oft-cited claim that there are 84,000 chemicals in commerce but only 200 of these have been tested for safety. Plastic containers have recycle codes on the bottom. The https:// ensures that you are connecting to the official website and that any information you provide is encrypted and transmitted securely. As is the case when foods are in direct contact with any packaging material, small, measurable amounts of the packaging materials may migrate into food and can be consumed with it. [28][29][30] Subsequent work found that it bound to estrogen receptors tens of thousands of times more weakly than estradiol, the major natural female sex hormone. [22][17][72], The health effects of BPA have been the subject of prolonged public and scientific debate,[12][13][14] with PubMed listing more than 16,000 scientific papers as of 2022. [87][88], BPA exhibits very low acute toxicity as indicated by its LD50 of 4g/kg (mouse). [8], Usually, the addition of acetone takes place at the para position on both phenols, however minor amounts of the ortho-para (up to 3%) and ortho-ortho isomers are also produced, along with several other minor byproducts. Epub 2014 Feb 4. c) Doerge DR, Twaddle NC, Vanlandingham M, Fisher JW. View our page to search various areas of interest and methodology. At 830C). The epoxide functional group is also collectively called epoxy. The CDC NHANES data are considered representative of exposures in the United States. The epoxide resins (also widely known as epoxy resins and, occasionally, as ethoxyline resins) are characterised by the possession of more than one 1,2-epoxy group (I) per molecule. Bisphenol-F can further link generating tri- and tetra-and higher phenol oligomers. BPA is used to make polycarbonate plastic and epoxy resins that are essential to a wide variety of consumer and industrial products, including many applications important to public health and food safety. High-performance epoxy resins are used to make aircraft, cars, bicycles, boats, golf clubs, skis and snowboards durable, flexible and strong. The chemical formula is (CH 3 ) 2 C(C 6 H 4 OH) 2. [99] Regardless, the remaining 29% of BPA will continue through to the environment, with low levels of BPA commonly observed in surface water and sediment in the U.S. and Europe. Epoxy resins made with BPA are tough and readily adhere to metal surfaces, making them excellent materials for protective coatings. [90] Different expression of ERR- in different parts of the body may account for variations in bisphenolA effects. BPA is an industrial chemical used to make a hard, clear plastic known as polycarbonate. NIEHS provides many opportunities for funding to individual researchers, organizations, and businesses.
