Neutral Protease Np-06 for Leather Hair Removal and Silk Degumming.

Neutral Protease NP-06 is produced from Bacillus subtilis through submerged fermentation, extraction and refining process. NP-06 catalyzes protein hydrolysis in neutral environment and generates peptide and a small quantity of amino acids.

Neutral protease NP-06 can be used in leather industries, especially suitable for leather hair removal; it can also be used for silk degumming.

NP-06 is stable with pH between 6.5 and 7.5. Inactivation is achieved quickly at pH below 5.0 or above 9.0. For maximum activity of NP-06, the optimal pH is from 6.8 to 8.0.

NP-06 is stable at temperatures below 37°C with pH from 7.0 to 8.0. It is unstable at temperatures above 45°C and inactivated quickly at temperatures above 60°C. For its maximum activity, the optimal temperature is about 50°C with pH around 7.2.

NP-06 has been formulated for optimal stability. Typical shelf-life is six months provided being stored below 25°C in its original packaging, sealed and unopened, protected from the sunlight. Its shelf-life will be eighteen months if it is stored properly at 0~10°C. Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement.

Inhalation of enzyme dust and mists should be avoided. In case of contact with the skin or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the Material Safety Data Sheet.
