What are the chemical properties of bisphenol A (BPA)?
BPA stands for bisphenol A. BPA is an industrial chemical that has been used to make certain plastics and resins since the 1960s. BPA is found in polycarbonate plastics and epoxy resins. Polycarbonate plastics are often used in containers that store food and beverages, such as water bottles. They may also be used in other consumer goods.

Phthalates in Food Packaging and Food Contact Applications
The FDA revoked authorizations for the food contact use of 23 phthalates and two other substances used as plasticizers, adhesives, defoaming agents, lubricants, resins, and slimicides.
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. [2] [7] BPA is produced on an industrial scale by the condensation reaction of phenol and acetone, and has a global production scale

- Where is BPA found in plastic?
- BPA is mostly found in plastics with the recycling symbol number 7. Bisphenols are also commonly used in flooring, car body coatings, adhesives, thermal paper, inks, textiles, paper and more. Which plastic bottles have BPA or other bisphenols?
- How do you know if a plastic is BPA free?
- There is no simple and easy way to tell if a plastic is BPA free. Your best bet is to avoid plastics that commonly contain bisphenols and when possible use an alternative material like glass or ceramic. Bisphenols like BPA will not be listed on a label. Some products will display a “BPA Free” but this does not ensure they are void of bisphenols.
- Do children's toys contain BPA?
- Children's toys may contain BPA, being used as an additive in other types of plastic (Staples et al., 1998). Bisphenol A is a high production volume chemical as there is an increasing demand for polycarbonates, and epoxy resins.
- Is plastic burning a source of atmospheric BPA?
- At the same time, a positive correlation was found between BPA and 1,3,5-triphenylbenzene, a tracer for plastic burning, in urban regions, indicating that the open burning of plastics in domestic waste should be a significant emission source of atmospheric BPA.
- What is BPA used for?
- The two primary uses for BPA, accounting for about 95 percent of all BPA produced, are to make polycarbonate plastic and epoxy resins. Both are high-performing materials that have been increasingly used for about five decades in a wide range of consumer and industrial applications.
