Some of these studies have raised questions about the safety of ingesting the low levels of BPA that can migrate into food from food contact materials. There is no scientific basis to say that BPA-free products are safer than products with BPA. How does BPA get into the body? In July, 2012, FDA took this action in response to a food additive petition filed by the American Chemistry Council (ACC) [9]. The condensation of acetone (hence the suffix 'A' in the name)[32] with two equivalents of phenol is catalyzed by a strong acid, such as concentrated hydrochloric acid, sulfuric acid, or a solid acid resin such as the sulfonic acid form of polystyrene sulfonate. One reason people may be concerned about BPA is because human exposure to BPA is widespread. [3]NTP-CERHR Monograph on the Potential Human Reproductive and Developmental Effects of Bisphenol A, NIH Publication No. [12][13][14] BPA is a xenoestrogen, exhibiting hormone-like properties that mimic the effects of estrogen in the body.

It is found in various products including shatterproof windows, eyewear, water bottles, and epoxy resins that coat some metal food cans, bottle tops, and water supply pipes. [1] This draft assessment was reviewed by a Subcommittee of FDAs Science Board, which released its report at the end of October 2008. [26] The utilization of BPA further expanded with discoveries at Bayer and General Electric on polycarbonate plastics. Bisphenol A can leach into food from the protective internal epoxy resin coatings of canned foods and from consumer products such as polycarbonate tableware, food storage containers, water bottles, and baby bottles. These plastics first appeared in 1958, being produced by Mobay, General Electric, and Bayer. Developed physiologically based pharmacokinetic models that can be used to predict the level of internal exposure to the active and inactive forms of BPA. 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. [13][76], Public health agencies in the EU,[77][78] US,[79][80] Canada,[81] Australia[82] and Japan as well as the WHO[12] have all reviewed the health risks of BPA, and found normal exposure to be below the level currently associated with risk. PA is also used in the production of epoxy resins. [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. View our page to search various areas of interest and methodology. On the regulatory front, FDAs regulations authorize FDA to amend its food additive regulations to reflect when certain uses of an additive have been abandoned. [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.

Epoxy resins have many uses including engineering applications such as electrical laminates for printed circuit boards, composites, paints and adhesives, as well as in a variety of protective coatings. Comparison of life-stage-dependent internal dosimetry for bisphenol a, ethinyl estradiol, a reference estrogen, and endogenous estradiol to test an estrogenic mode of action in Sprague Dawley rats. Thanks to their high strength, versatility, and excellent adhesion to a variety of surfaces, epoxy resins have gained wide acceptance in diverse applications (coatings, electrical, casting resins, composites, etc.). Per the diagram below, most epoxy resins are made by reacting Bisphenol A (BPA) with an excess of epichlorohydrin so the end groups are glycidyl ethers. BPA is an industrial chemical used to make a hard, clear plastic known as polycarbonate. The conclusion is not based simply on the number of studies, but more importantly on their quality and scientific value. [7] Thus, in bisphenol F, the F signifies formaldehyde. BPA can both mimic the action of estrogen and antagonise estrogen, indicating that it is a selective estrogen receptor modulator (SERM) or partial agonist of the ER. 2014 May;139(1):174-97. doi: 10.1093/toxsci/kfu022. FDA will also continue to consult with other expert agencies in the federal government, including the National Institutes of Health (and the National Toxicology Program), the Environmental Protection Agency, the Consumer Product Safety Commission, and the Centers for Disease Control and Prevention. BPA is also found in epoxy resins, which act as a protective lining on the inside of some metal-based food and beverage cans. Chemical Identity.
