Cellulase Compositions for Sugar Snake Degradation

Example 3

Multiple enzyme compositions comprising a cellulase were evaluated to determine sugar snake degradation performance as a baseline without potential surfactant synergy to assess the role of the enzyme composition versus improvement based on surfactant synergy. Compositions were prepared with 0.5 wt. % enzyme composition, 1.7 wt. % sodium citrate buffer, and water at a pH of 4.25. The four enzyme compositions tested were obtained from Novozymes and included: DRAIN EASE FLOW™, CELLUCLEAN CLASSIC 700T®, CELLUCLAST CONCENTRATED BG®, and Cellulase C. A sugar snake of equal mass was measured and the cleaning compositions were applied to it. The percent degradation of the sugar snake (based on mass) was evaluated after 2 hours of contact and after 24 hours of contact. The percent degradation is shown in FIG. 2 where 100 indicates 100% degradation. As can be seen in FIG. 2, CELLUCLAST CONCENTRATED BG® provided the best sugar snake degradation at both the 2-hour time and 24-hour time. DRAIN EASE FLOW™ and Cellulase C performed substantially similar and CELLUCLEAN CLASSIC 700T® did not appear to degrade the sugar snake at all.
