Abstract
The present invention provides a detergent composition comprising a quaternary ammonium compound of formula: R.sub.1 R.sub.2 R.sub.3 R.sub.4 N.sup.+ X.sup.-,wherein R.sub.1 is C.sub.8 -C.sub.16 alkyl, each of R.sub.2, R.sub.3 and R.sub.4 is independently C.sub.1 -C.sub.4 alkyl or hydroxy alkyl, benzyl or --(C.sub.2 H.sub.40).sub.x H where x has a value from 2 to 5, not more of R.sub.2, R.sub.3 or R.sub.4 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 CMC-method at 25.times.10.sup.-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.
