In the leather industry, pH is not just a technical indicator, itโs a true performance pillar that determines the pe*******on, reactivity, and stability of tanning agents.

1๏ธโฃ Controlling fiber opening : from soaking to pre-tanning, pH regulates collagen fibers. A pH thatโs too high or too low can cause unwanted degradation of proteins.
2๏ธโฃ Gradual, controlled evolution: pH must change step by step slowly decrease, then rise in a controlled way.
This regulated progression ensures :
โ๏ธ Uniform pe*******on of tanning agents, whether mineral, vegetable, or synthetic, throughout the dermis.
โ๏ธ Optimal fixation on collagen fibers, resulting in stable, resistant, and even leather.
โ๏ธ This principle also applies to the following stages, such as retanning, fatliquoring, and dyeing, to ensure an even and consistent distribution of the products.
Thatโs where 80% of the final leather quality is defined.
3๏ธโฃ Leather stability and durability: a well-tanned leather is, above all, a stable one.๏ฟฝThe right pH guarantees:
- Better mechanical strength
- Improved color fastness
- Greater resistance to moisture and aging
We develop chemical solutions that optimize pH at every stage, ensuring high-performing, stable leather that meets the most demanding technical standards.
