Bisphenol A
BPA is a main component of several high-performance plastics, the production of these is low compared to other plastics but still equals several thousand tons a year. Comparatively minor amounts of BPA are also used as additives or modifiers in some commodity plastics. These materials are much more common but their BPA content will be low.
Human exposure to bisphenol A (BPA) - PubMed
The plastic monomer and plasticizer bisphenol A (BPA) is one of the highest volume chemicals produced worldwide. BPA is used in the production of polycarbonate plastics and epoxy resins used in many consumer products. Here, we have outlined studies that address the levels of BPA in human tissues and fluids.
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.

Bisphenol A, or BPA, is an industrial chemical that has been used to make certain polycarbonate plastics and epoxy resins since the 1960s. The CDC found detectable levels of BPA in 93% of the Americans it tested, according to a 2012 BPA factsheet.
- Are You exposed to BPA in plastic?
- As a result of the presence of BPA in plastics and other commonplace materials, most people are frequently exposed to trace levels of BPA. The primary source of human exposure is via food, as epoxy and PVC are used to line the inside of food cans to prevent corrosion of the metal by acidic foodstuffs.
- Is BPA soluble in water?
- ?
- ) 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 reaction of phenol and acetone.
- What percentage of bisphenol A is used to make polycarbonate plastic?
- About 65–70% of all bisphenol A is used to make polycarbonate plastics, which can consist of nearly 90% BPA by mass. Polymerisation is achieved by a reaction with phosgene, conducted under biphasic conditions; the hydrochloric acid is scavenged with aqueous base.
- How are polyetherimides made from BPA?
- Polyetherimides such as Ultem can be produced from BPA via a nitro-displacement of appropriate bisnitroimides. These thermoplastic polyimide plastics have exceptional resistance to mechanical, thermal and chemical damage. They are used in medical devices and other high performance instrumentation.

- Does PVC contain BPA?
- PVC can contain BPA and its derivatives through multiple routes. BPA is sometimes used as an antioxidant in phthalates, which are extensively used as plasticizers for PVC. BPA has also been used as an antioxidant to protect sensitive PVC heat stabilizers.
