In washing agents containing tensides and cellulase, the properties of the cellulase which are relevant to the application were to be improved. This was essentially achieved in that use was made of a cellulase mixture in which the first component, with a CMCase activity of 1 U per litre and a protein concentration of a most 3 mg per litre, gives an increase in remission of at least 5 units in the secondary washing test and the second component, with a CMCase activity of 20 U per litre gives an increase in absorption in the cellulose decomposition test of at least 0.075.
L'invention vise à améliorer les propriétés de la cellulase, inhérentes à l'utilisation, dans des détergents qui contiennent des tensioactifs et de la cellulase. A cet effet, on utilise un mélange de cellulases dont le premier constituant, pour une activité de carboxyméthylecellulase d'1 U par litre et une concentration en protéines d'au plus 3 mg par litre, augmente la rémission d'au moins 5 unités dans le test de lavage secondaire, et dont le second constituant, pour une activité de carboxyméthylecellulase de 20 U par litre, augmente l'absorption dans le test de décomposition de la cellulose d'au moins 0,075.
