FDAs current perspective, based on its most recent safety assessment, is that BPA is safe at the current levels occurring in foods. Polycarbonate drinks containers are also a source of exposure, although most disposable drinks bottles are actually made of PET, which contains no BPA. [103], BPA is an environmental contaminant of emerging concern. [38][39][40] Spectroscopic data is available from AIST.[41]. Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. 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. [43][44] This is achieved by a reaction with epichlorohydrin under basic conditions. [105] As such, the precise effects of BPA on the growth, reproduction, and development of aquatic organism is not fully understood. [9][10] For epoxy resin, it is first converted to its diglycidyl ether (usually abbreviated BADGE or DGEBA). Toxicol Appl Pharmacol. Recently completed a rodent subchronic study [7] intended to provide information that would help in designing a long-term study that is now underway (see below). Bisphenol S (BPS) is an organic compound with the formula (HOC 6 H 4) 2 SO 2.It has two phenol functional groups on either side of a sulfonyl group. As an addition to this core study, FDA is providing extra animals and tissues to a consortium of grantees [8] selected and funded by the National Institute of Environmental Health Sciences to address other critical questions. In particular, infants are considered to be at greater risk,[83] leading to bans on the use of BPA in baby bottles and related products by the US,[84] Canada,[85] and EU[86] amongst others. The review was documented in four memoranda and their attachments: Strong consumer and scientific interest in the safety of BPA has prompted FDA to support additional studies to provide further information and address apparent inconsistencies in the scientific literature about BPA.

Other Details: - Bisphenol resin is extensively used with consumer products such as applying coatings inside of food and beverage cans as this leave no bad effects or any risk of hazard to human health. It is also a component in metal can coatings, which protect the food from directly contacting metal surfaces. 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. The conclusion is not based simply on the number of studies, but more importantly on their quality and scientific value. FDA can take this action on its own initiative or in response to a food additive petition that demonstrates that a use of a food additive has been permanently and completely abandoned. a) Churchwell MI, Camacho L, Vanlandingham MM, Twaddle NC, Sepehr E, Delclos KB, Fisher JW, Doerge DR. BPA is regularly used to strengthen products for human health and safety. [90] It can also protect it from deactivation from the SERM 4-hydroxytamoxifen (afimoxifene). 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. It is alcohol, ketone and ether soluble but presents low solubility in water and carbon tetrachloride. NIEHS sponsors and co-sponsors scientific meetings, conferences, and events throughout the year. While air, dust, and water are other possible sources of exposure, BPA in food and beverages accounts for the majority of daily human exposure. The hydroxy group may be derived from aliphatic diols, polyols (polyether polyols), phenolic compounds or dicarboxylic acids.

NIEHS intramural scientists have defined descriptive terms of particular relevance to their own research, and have ranked those terms accordingly. [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. Research studies pursued by FDAs National Center for Toxicological Research have [6]: Found evidence in rodent studies that the level of the active form of BPA passed from expectant mothers to their unborn offspring, following oral exposure, was so low it could not be measured. Polycarbonate is strong and durable, but over time it may break down from over use at high temperatures. FDA will continue to participate in discussions with our international regulatory and public health counterparts who are also engaged in assessing the safety of BPA. Bisphenol A was first synthesized by A.P. Pathways include photo-oxidation, or reactions with minerals such as goethite which may be present in soils and sediments. Epoxy groups located at both ends of the molecule can undergo reactions of ring-opening, cross-linking and solidity with amines, anhydrides, and other curing agents of epoxy resins.
