Bisphenol F (BPF) based epoxy resins are more flexible than that of BPA-based epoxies. Using the data and design from the rodent subchronic study, the National Toxicology Program/Food and Drug Administration (NTP/FDA) is conducting a long-term toxicity study of BPA in rodents to assess a variety of endpoints, including novel endpoints where questions have been raised. 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. 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.). NIEHS sponsors and co-sponsors scientific meetings, conferences, and events throughout the year. Industrially, a large excess of phenol is used to ensure full condensation; the product mixture of the cumene process (acetone and phenol) may also be used as starting material. The study included an in utero phase, direct dosing to pups to mimic bottle feeding in neonates, and employed a dose range covering the low doses where effects have been previously reported in some animal studies, as well as higher doses where estrogenic effects have been measured in guideline oral studies. 2005 2022 American Chemistry Council, Inc. Epoxy resins made with BPA are tough and readily adhere to metal surfaces, making them excellent materials for protective coatings. 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. 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. Recently, FDA granted two petitions requesting that FDA amend its food additive regulations to no longer provide for the use of certain BPA-based materials in baby bottles, sippy cups, and infant formula packaging because these uses have been abandoned. [15] Although the effect is very weak,[16] the pervasiveness of BPA-containing materials raises concerns, as exposure is effectively lifelong.

The results, released in 2018 by the U.S. National Toxicology Program, were accompanied by a statement from Dr. Stephen Ostroff, Deputy Commissioner for Foods and Veterinary Medicine at the U. S. Food and Drug Administration (FDA), saying: our initial review supports our determination that currently authorized uses of BPA continue to be safe for consumers.. This compound is synthesized by the condensation of acetone with phenol. [26] The utilization of BPA further expanded with discoveries at Bayer and General Electric on polycarbonate plastics. Some, but not all, plastics that are marked with recycle codes 3 or 7 may be made with BPA. bisphenol A: [noun] an industrial chemical compound C15H16O2 that is a component especially of hard plastics (such as polycarbonate) and epoxy resins. [100], Once in the environment BPA is aerobically biodegraded by a wide a variety of organisms. The results of this study showed no effects of BPA at any dose in the low-dose range. [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. As a result, FDA amended its food additive regulations to no longer provide for these uses of BPA. Transfer to a pear-shaped separatory funnel to separate the liquid, continue washing and separating with deionized water until the solution turns to neutral from alkaline. The FDAs National Center for Toxicological Research is continuing with an additional study: Rodent chronic toxicity study, which is currently underway. 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. [2] Also in 2008, the National Toxicology Program Center for the Evaluation of Risks to Human Reproduction, part of the National Institutes of Health, released the Monograph on the Potential Human Reproductive and Developmental Effects of Bisphenol A.[3]. At that time, another synthetic compound, diethylstilbestrol, was determined to be more powerful than estrogen itself, so bisphenol A was not used as a synthetic estrogen. These materials are much more common but their BPA content will be low. Among the non-food sources, exposures routes include through dust,[10] thermal paper,[20] clothing,[19] dental materials,[69] and medical devices. [4] The studies were evaluated for their relevance for regulatory hazard and/or risk assessment. Pharmacokinetics of bisphenol A in neonatal and adult CD-1 mice: inter-species comparisons with Sprague-Dawley rats and rhesus monkeys.
