Conzyme SPA-20 is a liquid form alkaline pectinase preparation. It is specially developed for bioscouring process of knitted natural cellulosic fibers such as cotton, linen, hemp and blend. It removes pectin and other impurities from cotton fibers without any degradation of the cellulose, soften and eliminate cotton seed to optimize dyeing performance.

9-12 months, subject to storage condition.
Safety
Enzyme preparations belong to protein, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or mucous membrane of nose, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
