1. 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.
