Bisphenol
The bisphenols (pronounced /ˈbɪs.fɪ.nɒl/) are a group of chemical compounds with two hydroxyphenyl functionalities. Most of them are based on diphenylmethane. The exceptions are bisphenol S, P, and M. "Bisphenol" is a common name; the letter following refers to one of the reactants. Bisphenol A is the most popular representative of this group, often simply called "bisphenol."

Health effects
Bisphenols A (BPA) and S (BPS) have been shown to be endocrine disruptors.[1][2] Due to its high production volumes BPA has been characterised as a "pseudo-persistent" chemical,[3] leading to its spreading and potential accumulation in a variety of environmental matrices.
Prevention measures
These products tend to release from the material when heated; as a precaution, it is recommended for the consumer:
- not to heat food in a plastic packaging in a microwave oven, or a tin can (its inside coating is often epoxy) with a bain-marie; [citation needed]
- use a pitcher material other than plastic, not a plastic bottle.[citation needed]
