Product Description

We have carved a reputed niche in industry for manufacturing and supplying Leather Alkaline Protease. It is a proteolytic enzyme which is utilized for tanning in leather industry. This enzyme belongs to protease class which is active at alkaline pH of 8 to 12. It is isolated from organisms and purified with help of chromatography & electrophoresis. Leather Alkaline Protease is known to preserve hides & skins, remove non fibrillar proteins & fats, and make leather soft & supple.


  • Works by hydrolyzing peptide bonds
  • Appears as translucent dark brown colored liquid
  • Helps in creating better tensile strength 


The alkaline protease was extracted from the liquid fermentation of Bacillus licheniformis (Bacillus licheniformis NO.2709).

This product is an enzyme preparation that catalyzes the hydrolysis of protein under the alkaline condition (pH9-12). It is applied in the industry of enzyme detergent, leather dehairing, silk degumming and protein hydrolysis.
