Epoxies have undergone extensive testing for health and environmental effects. In Europe, the safe use of epoxies is enabled by REACH, the most comprehensive product safety regulation in the world established in June 2007.
BPA, one of the most scrutinised substances, is needed to create BADGE, the most widely commercialised epoxy resin. However, BADGE is a completely different molecule with its own unique properties, not just an aggregate of BPA + epichlorohydrin.
Authorisation or restrictions for BPA will have no impact on epoxy polymers or BADGE, as BPA is used only as an intermediate to create BADGE. Once reacted with epichlorohydrin, the BPA has transformed into a new substance – BADGE. Intermediate uses are exempt from authorisation hence epoxy resins are not affected by the inclusion into Annex XIV.
