Due to its crosslinking properties, Glutaraldehyde is widely recognized as a very efficient alternative technology to Chromium-based tanning. Due to the potential risk of chromium VI formation in leather articles, the need for chromium-free tanning technology/alternatives has increased. Most chromium-free leathers today are tanned with Glutaraldehyde due to the following key features:
- Cost-efficient technology with broad applicability in pre-tanning and tanning
- As a reactive molecule, Glutaraldehyde is completely consumed in the leather tanning process, especially when basified after the completed reaction
- Residual Glutaraldehyde will react with present proteins in the processing float, resulting in no impact to the efficiency of the wastewater treatment
- Due to its complete reaction, there might be only traces of Glutaraldehyde present on or in the leather article after tanning (potential traces are far below the existing concentration limit of 30 mg/kg). Consequently, the residual Glutaraldehyde level is too low to lead to post-reactions affecting the quality of the leather or posing a risk to the environment and human health
- When used as recommended, Glutaraldehyde can be handled safely and sustainably
We are a leader in navigating the regulatory environment of Glutaraldehyde, ensuring the safety and sustainability of the technology.
Our portfolio currently contains two products that are dedicated to the leather tanning application: Glutaraldehyde 50% and Glutaraldehyde 24%. Product names may vary per region
