The bisphenols (pronounced /ˈbɪs.fɨ.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 following letter refers to one of the reactants. Bisphenol A is the most popular representative of this group, often simply called "bisphenol."

Preventive measures[edit]

Bisphenols A and S are endocrine disruptors.[citation needed] 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]
