Abstract
A detergent composition comprising a combination of cellulase enzymes is provided. The detergent composition comprises at least 1% by weight of a surfactant, at least 1% by weight of a builder and an effective amount of an enzymatic mixture capable of degrading cellulose. The enzymatic mixture comprises a combination of at least two cellulases, of which one is a surface-active cellulase having a cellulose-binding domain, and one is a nonsurface-active cellulase which does not possess a cellulose-binding domain. The nonsurface-active cellulase and the surface-active cellulase are in a weight ratio of from 1:2 to 20:1 in the detergent composition.
