Abstract
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 as well as improved softening and feel properties to cotton-containing fabrics.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
A detergent composition suitable for use with cotton-containing fabrics which comprises; a cleaning effective amount of a surfactant or a mixture of surfactants suitable for preparing an alkaline wash medium having a pH of from above 7 to about 9; and from about 0.01 to about 5 weight percent of a cellulase composition comprising at least 40 weight percent of endoglucanase III based on the total weight of exo-cellobiohydrolase, endoglucanase and β-glucosidase proteins in the cellulase compositionwherein said endoglucanse III is an endoglucanase component derived from any strain of Trichoderma ssp. which produces endoglucanase III and having a pH optimum of about 5.5 to 6.0, an isoelectric point of from about 7.2 to 8.0, and a molecular weight of about 23 to 28 Kdaltons.
