Research summary supplied by the authors
Bisphenol S and F are starting materials or undesired side products in the synthesis of syntans. They can be found in basically all syntans in a range from close to the detection limit up to several thousand parts per million. They can be detected in most leather articles by extraction. In an initiative by the European Chemicals Agency (ECHA) to drastically reduce bisphenols in consumer goods and in the environment, challenging limits were proposed in 2022. These limits would have had a strong impact on syntan portfolios of the leather chemical manufacturers and on many leather articles. After a public a consultation, ECHA has temporarily withdrawn the restriction proposal and wants to re-work it. Examples for reductions of both bisphenols in leather chemicals and the impact on extractions from leather articles made with these chemicals will be outlined in this article.
