Technical Parameters:

Applications:

Retanning, the stage where leather’s texture and performance are refined, further benefits from sodium formate’s properties. When combined with vegetable or synthetic tanning agents, it forms stable complexes with collagen’s carboxyl groups, strengthening the bond between tanning agents and fibers. This interaction results in leather with improved fullness, softness, and elasticity—qualities particularly prized in high-end applications like luxury shoe uppers and furniture upholstery. Tanners also rely on sodium formate to promote uniform penetration of retanning agents, reducing common defects such as hard spots or uneven coloring, thereby increasing production yields of grade-A leather.​
