TANIGAN®

Ultra low to zero BPS/BPF syntans

Addressing the very latest regulatory challenges

The Background

TFL is a leading global manufacturer and supplier of high quality syntans that are recognized worldwide under the famous brand names of SELLATAN® and TANIGAN®.

To maintain this lead TFL continually invest in pioneering research, development and extensive application support to keep you at the cutting edge of the very latest technological advances. The restriction draft of ECHA on Bisphenol A and other bisphenols of similar concern (BoSC) foresaw for leather a limit of 500 mg/kg BPS/BPF by 2025 and reducing further this limit to 10 mg/kg by 2030, has changed. The Federal Office for Chemicals (BfC), the German authority for REACH, has decided to temporarily withdraw the dossier without further information. It is therefore likely that the implementation of the restriction will be delayed by at least 18 months, and it is not yet clear whether the conditions will remain the same. However, based on all facts that ECHA have published in this context, there is currently no reason to believe that conditions for the leather application will significantly improve.

It is also important to note that Brands are inde-pendently implementing their own restrictions (RSL’s) not only in advance of any legislation, but the values can also be harsher, forcing the tanneries to comply with the low bisphenol limit in the leather supplied. TFL, as a global leader in chemicals for leather production, had immedi-ately started to develop products to address this new challenge once it became public.

Building on the leading SELLATAN® and TANIGAN® syntans global success, TFL launches the next generation of ultra-low or zero BPS/BPF syntans, now unified under the single brand name TANIGAN®. By working together with these new TFL syntans you will be ahead of any current or expected legislative restrictions. These next gen-eration products represent an indispensable new range of genuine replacement syntans that allows the production of leather below detection level (<10 ppm of bisphenols for the leather).

Please keep in mind that the vast majority of TFL’s comprehensive wetend retanning product port-folio is completely free of BPS and BPF under the following well-known trade names: RETINGAN®, MAGNOPAL®, LEVOTAN®, BLANCOROL®, TANNESCO®, DRYWALK®, LEUKOTANTM, LUBRITANTM, SELLASOL® and of course together with all TFL fatliquors and dye-stuff ranges etc.
