Abstract
Abstract A novel detergent composition for clothing comprises a cellulase having a non-degrading index of the following equation of not less than 500 ##EQU1## The composition can not only remove the dirt in clothing articles without damaging them but also show the effect of mitigating the roughness of cloth to the touch and the effect of preventing decoloration.
