Propionic acid in leather
In the leather industry, propionic acid has specific applications. During the tanning and post-treatment processes of leather, propionic acidcan be used as a pH regulator. It helps adjust the acidity and alkalinity of the tanning solution, improving the absorption of tanning agents and enhancing the quality of the leather, making it softer and more durable. Additionally, in the dyeing process, propionic acid aids in the dissolution and penetration of dyes, ensuring even and vibrant coloring.
