Smit has analysed its core-range on bisphenols. We will communicate openly our bisphenols values in our products to the industry, so our partners can make the responsible choice. For the long run, we are looking into bio-based alternatives to replace petrochemical key ingredients in our retanning products (see ESG report) in which we will continue to fulfill the lowest requirements of Bisphenol content in leather possible.

The products and presented values will be updated by new information provided in the course of time. Please note that these values relate to the retanning agent. Studies have shown that not all bisphenols will be taken-up by the leather and will partially end up in the waste-water.
