Dehairzyme is a bacterial alkaline protease enzyme produced by a selected strain of Bacillus species. The enzyme will hydrolyse proteins to short-chained peptide. Dehairzyme is a versatile leather unhairing enzyme for hides and skin. Dehairzyme is a bacterial alkaline protease leather un-hairing enzyme to be used in leather beam house processes. Dehairzyme effectively attacks the outermost sheath of the hair bulb resulting in better depiation, thereby produces flat leather without wrinkles and growth marks. It also removes connective tissue protein, thus loosening flesh and adipose tissue stuck to hides. The alkaline protease enzymes present in dehairzyme removes unwanted protein material like albumin and   mucin, without damaging the collagen. The ready to use formulation of enzymes and other ingredients given high -performance un-hairing, giving smooth grain, flat growth marks and assists in easy removal of hair and scud in the subsequent processes. It also reduces chemical consumption and water effluent problems. Wetting agents and detergents can be avoided while using this formulated product.

The required quantity of above un-hairing chemicals except the enzyme is mixed with 10-15% water to a smooth slurry/paste. The recommended dosage of enzyme is thoroughly mixed separately in a minimum quantity of water and kept aside for 15-20 minutes for enzyme stabilization. Just before pasting add enzyme to the paste and ensure proper mixing. Apply paste on the flesh side, pile and keep covered.
