Catalase enzyme for textile Conzyme CAT400

 PRODUCT DESCRIPTION  

Conzyme® CAT400 is an extremely high concentrated liquid catalase preparation. It is specially developed for textile application to remove residual hydrogen peroxide and improves the last preparation prior to dyeing; it works within wide pH range to completely remove residual hydrogen peroxide, with great reduction in consumption of hazardous chemicals and water. 

MECHANISM 

Catalase catalyzes the decomposition of hydrogen peroxide to water and oxygen.  

The reaction takes place efficiently under mild condition and doesn’t require the use of harsh chemicals harmful to fabrics, saving cost, reducing processing time and environmental load.

SAFE HANDLING PRECAUTIONS

Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor. 

WARNINGS

Keep sealed after use every time to avoid microbial infections and inactivation of enzymes until its finish.
