Bisphenol A CAS  80-05-7 , also known as BPA, is an organic compound with the molecular formula C15H16O2,

Bisphenol A is used in industry to synthesize materials such as polycarbonate (PC) and epoxy resin. Since the 1960s, it has been used to manufacture plastic (milk) bottles, suction cups for young children, and inner coatings for food and beverage (milk powder) cans. BPA is ubiquitous, from mineral water bottles, medical devices, and the interior of food packaging. Every year, 27 million tons of plastic containing BPA are produced worldwide. But BPA can also cause endocrine disorders, posing a threat to the health of fetuses and children. Obesity caused by cancer and metabolic disorders is also believed to be related to this. The European Union believes that bottles containing bisphenol A can induce precocious puberty, and from March 2, 2011, the production of baby bottles containing the chemical bisphenol A (BPA) will be banned.

Purpose

Bisphenol A is one of the most widely used industrial compounds in the world, mainly used in the production of various polymer materials such as polycarbonate, epoxy resin, polysulfone resin, polyphenylene ether resin, unsaturated polyester resin, etc. It can also be used to produce fine chemical products such as plasticizers, flame retardants, antioxidants, heat stabilizers, rubber antioxidants, pesticides, coatings, etc.

In the manufacturing process of plastic products, the addition of bisphenol A can make them colorless, transparent, durable, lightweight, and outstanding impact resistance, especially to prevent acidic vegetables and fruits from corroding metal containers from the inside. Therefore, it is widely used in the packaging of canned food and beverages, milk bottles, water bottles, sealants for dental fillers, glasses, and the manufacturing process of hundreds of other daily necessities.
