New: Low bisphenol retanning range with BioTan XP 01L

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, our subisidairy Smit has 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.

The future of retanning is now, with BioTan XP 01L.  

Imagine retanning of the future; low emissions, bio-based ingredients and free of bisphenol and formaldehyde. With the power of a traditional phenolic retanning agent and no compromise on the performance, fullness and softness of the leather BioTan XP 01L offers just that.

No detectable bisphenol. With tanning power.

BioTan XP 01L is the latest innovation of Smit wet end and part of their recently launched Renewability range. An innovative phenolic retanning agent that is partly bio-based. It’s not a blend and not a filler. It is your next step in meeting the demand for low emissions and to build further towards a sustainable way of leather making. 

No detectable bisphenol values 
Multiple independent test results confirm this: bisphenol-F and bisphenol-S values are always below detection limit in BioTan XP 01L. On leather, so on Zeo White or wet blue retanned with BioTan XP 01L, analyses also show bisphenol values below detection limits on BPS, BPF, BPA, BPB. 

 The main benefits of BioTan XP 01L:

  • Tanning power, no filler 
  • Bio-based polymer produced by patented technology 
  • No detectable bisphenol
  • Free of formaldehyde 
  • Very low emission values 

BioTan XP 01L gives you sustainable future-proof retanning without compromises on leather performance. Like no other retanning agent does.
