It is important to note that scientific experts at FDA, and other regulatory bodies, review the full weight of the scientific evidence when making decisions about safety. Many of these studies addressed how the body disposes of or metabolizes BPA. Polycarbonate is strong and durable, but over time it may break down from over use at high temperatures. Copolymer epoxy resins were prepared using a two-step process in which 10, 30 and 50% of bisphenol-A was replaced with liquefied bamboo. [74] These interactions are all very weak, but exposure to BPA is effectively lifelong, leading to concern over possible cumulative effects. At 830C). The lowest molecular weight an epoxy resin of the DGEBA type can have is 340, but if two elements together can form different molecular weights when they react, the epoxy resin will contain a mixture of epoxy molecules of varying lengths. This results in much lower internal exposure of BPA (i.e., the active form) than what occurs from other routes of exposure such as injection. 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. An official website of the United States government. One reason people may be concerned about BPA is because human exposure to BPA is widespread. Bisphenol A diglycidyl ether (DGEBA) can be called a small-molecule adhesive.

Epoxy resins made with BPA are tough and readily adhere to metal surfaces, making them excellent materials for protective coatings. Bisphenol A (BPA) is a chemical produced in large quantities for use primarily in the production of polycarbonate plastics. The FDAs National Center for Toxicological Research is continuing with an additional study: Rodent chronic toxicity study, which is currently underway. Scientific research shows that in humans, BPA is quicklymetabolized and eliminated from the body it does not accumulate in blood or tissues. [96] The solubility of BPA in water is low (~300g/ton of water)[2] but this is still sufficient to make it a significant means of distribution into the environment. 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. FDAs current perspective, based on its most recent safety assessment, is that BPA is safe at the current levels occurring in foods. Also, learn about different types of resins available and how to further improve their properties. NIEHS sponsors and co-sponsors scientific meetings, conferences, and events throughout the year. The results of the independent evaluations were released in April 2010, as FDA made the CFSAN report and other relevant information available for public comment. Toxicol Lett. The .gov means its official. Government regulators have the responsibility of reviewing all studies and considering issues like study design and quality and whether the result of any particular study was repeated in other studies. Concerns about the health effects of BPA have led some manufacturers replacing it with other bisphenols, such as bisphenol S and bisphenol F. These are produced in a similar manner to BPA, by replacing acetone with other ketones, which undergo analogous condensation reactions. This compound is synthesized by the condensation of acetone with phenol. This allows exposure to be easily determined by urine testing, facilitating convenient biomonitoring of populations. BPA is a structural component in polycarbonate beverage bottles. In addition, FDA actively supported and participated in the Expert Consultation on BPA convened by World Health Organization and the Food and Agriculture Organization of the United Nations on November 2-5, 2010, in Ottawa, Canada. .
