Title:

A Low-Cost Chromium-Free Tanning Gel
Value Proposition:

Tanning Gel for Chrome Free Leather Manufacturing
Summary Application:
  • Globally, chromium-based tanning system is widely practiced (85-90%)
  • Increase in demand for chromium-free tanning systems due to the toxicity associated with Cr(VI)
  • The present chromium-free tanning systems are not widely practiced due to high tanning cost (> ₹ 15.0/Sq.ft) and lack of versatility
  • The present technology deals with the development of low-cost chromium-free tanning gel
Advantages:
  • Nature of the Product: Gel
  • Active Ingredients: Non-chrome inorganic polymers
  • Application pH range: 3.0-6.5
  • Leather Shrinkage Temperature: 80-85 ℃

  • Sustainability Benefits

    • Zero hazardous chemicals
    • No risk for Cr(VI) formation
    Energy and resource-efficient system
