Bisphenol-free retanning and filling agents

New challenges – innovative products: Zschimmer & Schwarz now offers customers alternatives that are more environmentally friendly

In the past, Bisphenol A (BPA) was present, amongst others, in baby bottles and thermal paper. Due to its endocrine effect on humans and the environment, it is no longer used for these purposes. In the future, the use of other, structurally similar bisphenols is supposed to be regulated. In small quantities, two of these substances (Bisphenol F und Bisphenol S) are present in synthetic tanning agents, which have been used in the retanning of leather for decades.

The current draft of the European Chemicals Agency (ECHA) provides for the introduction of strict limits for bisphenols in leather articles and chemical auxiliaries for leather processing. This poses a great challenge to both tanneries and the chemical industry. Zschimmer & Schwarz has addressed this issue at an early stage and now presents newly developed bisphenol-free retanning and filling agents which do not contain any of these potentially harmful substances.

The new products TAFIGAL HFB, TAFIGAL S-TF and NOVALTAN S-VF of Zschimmer & Schwarz allow the production of bisphenol-free leathers with comparable properties to previous articles. With their high proportion of bio-based raw materials and good biodegradability, two of the new products even meet the high requirements of the S-Range, a particularly sustainable product range of the Leather Auxiliaries business unit of Zschimmer & Schwarz.

The new bisphenol-free tanning and filling agents have already been successfully tested on various leathers at Zschimmer & Schwarz's test tannery in Lahnstein and are available now.
