| abstract |
The present invention provides a detergent composition comprising a quaternary ammonium compound of formula: R1R2R3R4N+ X-, wherein R¿1? is C8-C16 alkyl, each of R2, R3 and R4 is independently C1-C4 alkyl or hydroxy alkyl, benzyl, or -(C2H40)xH where x has a value from 2 to 5, not more than one of R2, R3 or R4 being benzyl, and X is an anion, and a cellulase characterized in that said cellulase provides at least 10 % removal of immobilized radio-active labelled carboxymethylcellulose according to the C14 CMC-method at 25 x 10?-6¿ % by weight of cellulase protein in the laundry test solution. According to the present invention, a preferred cellulase consists of a homogeneous endoglucanase component which is immunoreactive with a monoclonal antibody raised against a partially purified = 43 kD cellulase derived from Humicola insolens DM 1800. |
