Abstract
Disclosed are detergent compositions containing a cleaning effective amount of a surfactant or a mixture of surfactants and from about 0.01 to about 5 weight percent of substantially pure EG III cellulase. Preferably, the detergent composition contains no more than about 5 weight percent of CBH I type components based on the total weight of cellulase proteins. When employed in aqueous wash media, the detergent compositions impart color retention/restoration properties to cotton-containing fabrics.
