CA 2093422

Disclosed are cellulase compositions containing one or more endoglucanase components and less than about 5 weight percent of CBH I type components. When incorporated into detergent compositions and used in acidic, neutral, or alkaline washing media, such cellulase compositions impart rotor retention/restoration properties as well as improved softening properties to cotton-containing fabrics. Additionally, such compositions impart reduced strength loss to cotton-containing fabrics as compared to cellulase compositions containing greater amounts of CBH I type components.

Compositions de cellulase contenant un ou plusieurs constituants d'endoglucanase et moins d'environ 5 % en poids de constituants de type CBH I. Lorsqu'on les ajoute à des compositions de détergent et qu'on les utilise dans des milieux de lavage acide, neutre ou alcalin, lesdites compositions de cellulase confèrent des propriétés de rétention/reconstitution ainsi que des propriétés assouplissantes améliorées à des tissus contenant du coton. De plus lesdites compositions confèrent une moindre perte de résistance à des tissus contenant du coton comparées à des compositions de cellulase contenant des quantités supérieures de constituants de type CBH I.
