Leather tanning

The phenolic structure of lignin yields benefits in tanning and leather applications.

Excellent water solubility and dispersing properties as well as suitable molecular mass distribution and low viscosity of aqueous solutions of lignin support fast, nearly complete penetration of hides, with physio-chemical reaction progressing over time.

Le lignosulfonate est un dérivé de la lignine très soluble et un produit issu du procédé de fabrication au bisulfite.

Our lignin is used in a variety of industrial and agricultural areas for various applications.
