The present invention relates to detergent compositions or components thereof containing a cellulytic enzyme and one or more cationic surfactants of the formula: R1R2R3R4N+ X- in which R1 is a hydroxyalkyl group having no greater than 6 carbon atoms; each of R2 and R3 is independently selected from C1-4 alkyl or alkenyl; R4 is a C5-9 alkyl or alkenyl; and X- is a counterion. The cationic surfactant may comprise a mixture of surfactants where at least 10 % by weight of the mixture has R4 of C9 or below, or where R4 is a Cn alkyl group of from more than 8 to 11, and a C(n-2) alkyl group, respectively.
La présente invention porte sur des compositions détergentes ou leurs composants contenant une enzyme cellulytique et un ou plusieurs tensioactifs cationiques de la formule: R?1¿R?2¿R?3¿R?4¿N?+¿ X?-¿ dans laquelle R?1¿ représente un groupe hydroxyalkyle ne possédant pas plus de 6 atomes de carbone; chacun des R?2¿ et R?3¿ est indépendamment sélectionné parmi alkyle ou alcényle en C¿1-4?; R?4¿ représente un alkyle ou alcényle en C¿5-9?; et X?-¿ est un contre-ion. Le tensioactif peut comprendre un mélange de tensioactifs, au moins 10 % en poids de ce mélange renfermant un R?4¿ en C¿9? ou moins, ou bien dans lequel R?4¿ représente un groupe alkyle en C¿n? possédant plus de 8 et jusqu'à 11 atomes de carbone, et un groupe alkyle en C¿(n-2)?, respectivement.
