BPA

Bisphenol A

Bisphenol A (BPA) is an organic synthetic compound with the chemical formula (CH3)2C(C6H4OH)2 belonging to the group of diphenylmethane derivatives and bisphenols, with two hydroxyphenyl groups. It is a colorless solid that is soluble in organic solvents, but poorly soluble in water.

BPA is a starting material for the synthesis of plastics among which there are certain polycarbonates and epoxy resins, as well as some polysulfones and certain niche materials. BPA-based plastic is known to be clear and tough, and is transformed into different common consumer goods, such as plastic bottles (e.g. water bottles), sports equipment, CDs, and DVDs. Epoxy resins, which also contain BPA, are used to line water pipes, as well as coatings on the inside of a number of food and beverage cans and finally, in making thermal paper which is used, for instance, in sales receipts.
