Proviera – Probiotics for Leather can be used on any type of hide and skins and are applicable for most leather manufacturing stages. They are 100% biodegradable and hazardless, resulting in less chemical usage, water usage, and waste. Because they prevent against putrefaction for up to 24 hours, they eliminate the need for bactericides, reducing costs, improving effluent treatment plant performance, and minimizing the risk of bactericide-related allergies for tanners.

Proviera products are NSF (National Sanitation Foundation) certified. Learn more about what that means >
