Textile biopolishing acid cellulase enzyme Conzyme® DL7

Description

Conzyme® DL7 is a liquid acid cellulase preparation developed for fabric and garment biopolishing. It improves the handfeel and appearance of fabrics and permanently reduces the tendency of pilling. It is especially suitable for the finishing processes of cellulosic fabrics made of cotton, linen, viscose or lyocell.

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.
