A detergent composition containing a combination of cellulase enzymes is provided. The detergent composition comprises at least about 1 % by weight of a surfactant, at least about 1 % by weight of a builder and an effective amount of an enzymatic mixture capable of degrading cellulose. The enzymatic mixture comprises a combination of at least two cellulases, of which one is a surface-active cellulase having a cellulose-binding domain, and one is a nonsurface-active cellulase which does not possess a cellulose-binding domain. The nonsurface-active cellulase and the surface-active cellulase are in a weight ratio of from about 1:2 to about 20:1 in the detergent composition.
Cette invention concerne une composition détergente contenant une combinaison de cellulases. Cette composition contient au moins 1 % en poids environ d'un tensioactif, au moins 1 % en poids environ d'un adjuvant pour détergents et une quantité efficace d'un mélange enzymatique capable de dégrader la cellulose. Ce mélange enzymatique comporte une combinaison d'au moins deux cellulases, l'une de ces cellulases étant une cellulase active en surface et l'autre étant une cellulase non active en surface ne possédant pas de tel domaine. La cellulase non active en surface et la cellulase active en surface sont présentes dans la composition détergente avec un rapport de poids compris entre 1 pour 2 environ et 20 pour 1 environ.
