Brief Description

Description :

Lime and sodium sulfide is completely eliminated during dehairing and fiber opening process for raw materials by adding water and proteolytic enzyme. It exhibits activity at experimental pH and experimental temperature, optionally in the presence of silicate salt to produce soft and subtle leather.
