At the forefront of health protection
The range of retanning agents with low bisphenol content meet the demands for a healthier future for the leather industry.
DDS (Dihydroxy-Diphenyl Sulphonic syntans) with ultra-low Bisphenol content: Advanced Technology for Sustainable Synthetic Tannins
We have introduced a new line of DDS synthetic tannins with extremely low bisphenol levels. This innovative solution delivers the same technical performance as traditional products, while significantly reducing toxicological and environmental impact.
Through an advanced development process:
- BPF and BPA have been completely eliminated
- The BPS content in the product is negligible and does not trigger labeling requirements
All this without compromising quality, softness, color, or fastness.
From an environmental perspective, our approach ensures a sustainable impact fully aligned with the latest standards.
While the complete elimination of BPS remains a challenge, the total removal of BPF is already a concrete achievement—scalable and compliant with emerging regulations.
This innovative project is being unveiled for the first time at the IULTCS 2025 conference.
Reducing bisphenols in leather: a challenge to be met
As of January 2023, BPS and BPF are listed in the ‘Bisphenols Substance of Concern’ of ECHA’s ‘Substances of Very High Concern’ (SVHC) register. Ongoing regulatory developments bring clear consequences for the leather sector. Indeed, the pressing demands for stricter limits on bisphenol content, both in articles and in chemical auxiliaries, could lead to stricter labelling requirements and product restrictions in the near future.
Increased safety without compromising product and article performance
As one of the major players in the leather chemicals sector, GSC Group feels called upon to address the issue and propose environmentally friendly alternatives that pose no potential risk to human health. Our new range of low bisphenol retanning agents guarantee the same high performance, whilst adding a variety of desirable properties into the leather. These products are highly adaptable, suiting a wide variety of articles.
