Neutralizing agents for optimal performance

The use of suitable neutralizing agents is essential to the optimal performance of retanning agents, fatliquors and dyes. Stahl’s high-performance neutralization agents adjust the pH of the leather to the required value. And with tanners keen to reduce their environmental impact, it’s good to know that all our neutralizing agents comply with the Zero Discharge of Hazardous Chemicals (ZDHZ) Manufacturing Restricted Substances List (MRSL), and therefore are part of our Stahl Neo® portfolio.
