Abstract
AbstractThe use of cellulases in detergents is gaining ground rapidly due to their ability to maintain clear colors, a smooth surface, and softness in cotton fabrics. This is due to the hydrolytic action on the fuzz and pill, which scatters light thereby giving a worn and faded look to the garments. Detergent cellulases must be stable to conditions of alkaline pH and to other components present in the formulation. Most literature in this area is patented. Our previous work demonstrated an excellent alkali stability of commercially available acid cellulases modified by maleic anhydride and N‐bromosuccinimide. The present work reports on screening for cellulases in commercially active detergents and the stability of these chemically modified cellulases vis‐à‐vis native cellulase in biodetergents and in detergents without enzymes at 30, 50, and 85°C for up to 120 min. The results obtained showed that modified cellulases have distinctly better stability than the native cellulase in the chosen detergents.
