It may also be used as an ingredient in some resins, which can act as a lining on the inside of some metal food and drink cans. Liquid Epoxy Resins Show entries [28], The synthesis of BPA still follows Dianin's general method, with the fundamentals changing little in 130 years. [92][101][102] Its half life in water has been estimated at between 4.5 and 15 days, degradation in the air is faster than this, while soil samples degrade more slowly. Food cans and other metal containers may be coated with epoxy resin linings made with BPA to help prevent direct food contact with metal, which helps protect food from contamination and spoilage. [38][39][40] Spectroscopic data is available from AIST.[41]. [42] This process converts the individual molecules of BPA into large polymer chains, effectively trapping them. 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. [34] These are not always removed and are known impurities in commercial samples of BPA. Products made from BPA meet high-performance demands. Some, but not all, plastics that are marked with recycle codes 3 or 7 may be made with BPA. 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. FDA will update its assessment of BPA and will take additional action if warranted. Because of its extreme durability and strength, polycarbonate plastic is particularly useful for making component parts that need to be thin and light, but strong.
