Bisphenol A is now deeply imbedded in the products of modern consumer society, not just as the building block for polycarbonate plastic (from which it then leaches as the plastic ages) but also in the manufacture of epoxy resins and other plastics, including polysulfone, alkylphenolic, polyalylate, polyester-styrene, and certain polyester resins. Bisphenol A is used primarily to make plastics, and products containing bisphenol A-based plastics have been in commerce use since [14] At least 8 billion pounds of BPA are used by manufacturers yearly. [15] It is a key monomer in production of epoxy resins [16] [17] and in the most common form of polycarbonate plastic. [5] [18] [19] The overall reaction to give .

Bisphenol A (BPA) What is BPA. Bisphenol A, more commonly known as BPA, is a chemical widely used to make polycarbonate plastics and epoxy resins. Where is BPA found. Polycarbonate plastics have many applications including use in some food and drink packaging such as water and baby bottles, compact discs, impact-resistant safety equipment, andFile Size: KB.

Bisphenol A (BPA) is used to produce certain types of plastic that are used in thousands of formulations for myriad products.

Containers made with these plastics may expose people to small amounts of BPA in food and water. Medical devices and other more ubiquitous products, such as thermal paper coatings, also may contribute significantly to human exposure. Bisphenol A, colorless crystalline solid in the family of organic compounds and used in the manufacture of polycarbonate plastics and epoxy resins.

It is widely known for its tendency to leach from these materials, which has made it a subject of public health and environmental concern. Bisphenol A (BPA) is an organic synthetic compound originally recognized as a potential synthetic estrogen in the s.

BPA is considered a possible human endocrine disrupter and is used extensively today in plastics production and in epoxy resins. Bisphenol A (BPA) is a high production volume chemical that is widely used in the manufacture of consumer products such as polycarbonate plastics, epoxy resin liners of canned foods, some dental sealants and composites, and thermal receipts.

Due to its widespread use in consumer products, exposure to BPA is by: Bisphenol A controversy centers on concerns and debates about the biomedical significance of bisphenol A (BPA), which is a precursor to polymers that are used in some consumer products, including some food containers.

Bisphenol A is a high production-volume chemical used in the manufacturing of plastics. While the first biological effects of BPA were described more than 75 years ago, a wider picture of the toxicity effects from BPA exposure has recently emerged.

In a recent article, vom Saal and Hughes () proposed that a new risk assessment on bisphenol A (BPA) is needed because of the availability of extensive new literature, including “recent epidemiologic evidence that BPA is related to disease in women.” Specifically, the only research that vom Saal and Hughes cited as evidence relating BPA to disease is a study by Cited by:   BPA stands for bisphenol A.
