Let’s reduce the levels of bisphenol in leather, together

High performing retanning solutions
Low on bisphenol emissions

Bisphenols have become an important topic of discussion in the leather industry, especially since the restriction proposal of the European Chemicals Agency on bisphenols. To meet regulations and to hold on to our mission statement, to create a sustainable leather value chain, we have developed a special range of wet end solutions optimized on bisphenols for high quality leather.

We offer syntans with low bisphenol values and introduce BioTan XP 01L, an innovative retanning agent with no detectable bisphenol. All our bisphenol optimized solutions are thoroughly tested, both on performance and on bisphenol limits.

Stay ahead of regulations and improve your sustainability

Do you want to stay future-proof and optimize your leather recipe and processing on bisphenols without compromising on leather performance? Reach out. We are here to offer you advice and technical support.
