Abstract
Research summary supplied by the authors
Bisphenols are under scientific and regulatory scrutiny due to their endocrine activity and potential environmental and health risks. In leather production, certain bisphenols can occur as ingredients or byproducts in leather chemicals and may transfer into finished leather. Although the planned EU restriction in 2023 was withdrawn, bisphenols remain relevant for ongoing assessments and regulatory discussions. In addition to EU regulations, international regulatory frameworks such as California Proposition 65 further contribute to the global relevance of this topic. This presentation provides an overview of bisphenols relevant to leather and leather chemicals, and potential pathways in leather processing. The current regulatory situation is outlined, including the withdrawn restriction, ongoing evaluations, and expected next steps. It is emphasized that EU regulations apply regardless of the country of production, affecting imported leather, and that brand-specific restricted substance lists also need to be considered. Analytical methods for measuring bisphenol levels and their transfer into leather are highlighted. It will be shown that based on experimental data obtained from practical test setups, these levels can also be calculated. Finally, strategies to reduce bisphenols in leather are discussed, supporting compliance with current and potential future regulatory requirements.
