Bisphenols are a family of synthetic organic chemicals, most of them being used for the production of some polycarbonates (plastics with a very large number of uses), as well as for the production of some of epoxy resins (especially used in cans), or as developer for the majority of thermal papers (eg receipts).
There are more than twenty bisphenols, among which bisphenols A, S and F seem to be the most widely used. Bisphenols are named with the common name of the "bisphenol" family to which is added one or more letters symbolizing the reagent or reagents used to achieve the synthesis of the substance under consideration: bisphenol A is thus a bisphenol synthesized by reaction of Acetone (A) with phenol.
Due to their reprotoxic character (confirmed for bisphenol A) and their potential applications (in particular for the manufacture of food containers), the use of some of bisphenols (bisphenol A and bisphenol S) is regulated in France and in the EU.
In these webpages, we present information on various families of molecules that are alternatives to bisphenols (isosorbides, polyesters, etc.), or alternatives to materials that require bisphenols, by illustrating them with accurate examples of substitution and from concrete practices or experiences in supply chains. To facilitate access to a synthetic vision, a summary table is regularly updated and proposed on the site.
