Application

In the hair-removal stage of leather processing, sodium thiosulfate holds substantial importance. It has the ability to break the disulfide bonds (-S - S -) that are present in the hair. Once these bonds are severed, the connection between the hair and the leather becomes less tenacious. Consequently, the hair can be effortlessly separated from the surface of the leather, which significantly eases the hair-removal procedure in the leather production process.
