1. Bisphenol A

   Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. It is a colourless solid which is soluble in most common organic solvents, but has very poor solubility in water. BPA is produced on an industrial scale by the condensation of phenol and acetone, and has a global production scale which is expected to reach 10 million tonnes in 2022.BPA's largest single application is as a co-monomer in the production of polycarbonates, which accounts for 65–70% of all BPA production. The manufacturing of epoxy resins and vinyl ester resins account for 25–30% of BPA use. The remaining 5% is used as a major component of several high-performance plastics, and as a minor additive in PVC, polyurethane, thermal paper, and several other materials. It is not a plasticizer, although it is often wrongly labelled as such. The health effects of BPA have been the subject of prolonged public and scientific debate. BPA is a xenoestrogen, exhibiting hormone-like properties that mimic the effects of estrogen in the body. Although the effect is very weak, the pervasiveness of BPA-containing materials raises concerns, as exposure is effectively lifelong. Many BPA-containing materials are non-obvious but commonly encountered, and include coatings for the inside of food cans, clothing designs, shop receipts, and dental fillings. BPA has been investigated by public health agencies in many countries, as well as by the World Health Organization. While normal exposure is below the level currently associated with risk, several jurisdictions have taken steps to reduce exposure on a precautionary basis, in particular by banning BPA from baby bottles. There is some evidence that BPA exposure in infants has decreased as a result of this. BPA-free plastics have also been introduced, which are manufactured using alternative bisphenols such as bisphenol S and bisphenol F, but there is also controversy around whether these are actually safer.

1. Bisphenol A

   Bisphenol A is a man-made carbon-based synthetic compound with the chemical formula (CH3)2C(C6H4OH)2 belonging to the group of diphenylmethane derivatives and bisphenols. BPA is used to make certain plastics and epoxy resins; it has been in commercial use since 1957. BPA-based plastic is clear and tough, and is used to make a variety of common consumer goods and for industrial purposes, like lining water pipes. Epoxy resins containing BPA are used as coatings on the inside of many food and beverage cans. It is also used in making thermal paper such as that used in sales receipts. It is part of the bisphenols group of chemical compounds with two hydroxyphenyl functionalities. It is a colorless solid that is soluble in organic solvents, but poorly soluble in water. Bisphenol A has a vapor pressure of 5×10^−6 Pa. BPA exhibits hormone-like properties that raise concern about its suitability in consumer products and food containers. Since 2008, several governments have questioned its safety, which prompted some retailers to withdraw polycarbonate products. A 2010 report from the United States Food and Drug Administration warned of possible hazards to fetuses, infants, and young children. In September 2010, Canada became the first country to declare BPA a toxic substance. The European Union, Canada, and recently the United States have banned BPA use in baby bottles.

Examples of bisphenol A in a Sentence

1. Sara Gottfried:

   The important thing is to realize we all get exposed to endocrine disrupters, [which are] these artificial chemicals that are in plastics. We get exposed to them in a lot of different ways-- receipts that you get at your local store often are coded with bisphenol A (BPA), which acts on your testosterone levels. So in women it tends to make you raise your testosterone, and in men it tends to lower your testosterone. So, this acts as an endocrine disrupter, and we want to stop that war that’s happening in the body and get rid of those toxins.
