|Bisphenol PH||24038-68-4||2-Phenylphenol||Acetone||5,5’ -(1-Methylethyliden)-bis[1,1’-(bisphenyl)-2-ol]propane|
Bisphenols A and S are endocrine disruptors. 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;
- use a pitcher material other than plastic, not a plastic bottle.
