BPA restriction proposal and preliminary EFSA opinion
The German Federal Environmental Protection Agency (Umweltbundesamt, UBA) in cooperation with the German Federal Institute of Occupational Safety and Health (Bundesamt für Arbeitsschutz, BAUA) announced plans for restricting uses of BPA that lead to releases of BPA to the environment. However, the actual scope of the restriction was only outlined broadly and not defined to a greater level of detail. Following that announcement, stakeholders are invited to provide data on their uses and provide data related to the use of BPA and/or BPA-based polymers. Of special interest to the authorities are a description and quantification of use scenarios which do or do not release BPA to environmental compartments such as water, air, sediment and soil.”
The intention for the restriction has been submitted by BAUA and published on the ECHA website.
- BAUA and UBA anticipate submission of the Annex XV restriction dossier on October 7, 2022 at the latest, followed by a conformity check and subsequently followed by a formal public consultation of the dossier (early 2023)
- Parallel to the public consultation, the Risk Assessment Committee (RAC) and the SocioEconomic Analysis Committee (SEAC) will develop their opinions and provide them via ECHA to the EU Commission (late 2023 / early 2024)
- The EU Commission will develop a restriction proposal for the amendment of Annex XVII
within 3 months after receipt of the committee opinions and taking into account the results of the public consultation (2024 final dossier to Commission)
- The final decision on the restriction proposal is taken through the comitology process. Upon conclusion of this process, the restriction is added to REACH Annex XVII (anticipated earliest Q1 2025)
Possible Impact on Epoxy technology
While the scope of the restriction is not clear based on the information provided in the announcement or in the published intention, additive uses of BPA in general, but possibly including hardeners formulated with BPA, are anticipated to be subject to the proposed restriction. Where applicable, Epoxy Europe members have, or are in the process of, reformulating such products in line with market developments. Epoxy Europe will follow-up with UBA to better understand the reference to limits for release rates of BPA to the environment from articles. Based on data produced by Epoxy Europe and provided to the UBA, releases of BPA from articles is minimal. Recent modelling studies, also shared with UBA, have shown that less than 1% of the emissions to the environment are related to polymerised materials. Any data available in the value chain that further corroborates this aspect should be provided to the process (see below).

METHODS FOR BPA MEASUREMENT
These standard operating procedures (SOP) developed by Solvias describe quantitative test methods for the determination of Bisphenol-A (BPA) in liquid (1) and solid (2) epoxy resins by liquid chromatography-mass spectometry (LC/MS). The specific mass of Bisphenol A is measured in the selected ion monitoring mode (SIM -mode).
Method 1: SOP C52.S1593_02 ; method used to determine Bisphenol-A in different BPA-epoxy resins (liquid).
Method 2: CSOP-0724_01 ; method for the determination of Bisphenol-A (BPA) in solid epoxy resins by LC/MS.
