Detergent compositions containing enzymes and calcium or magnesium ions are found to be more stable when the alkyl benzene sulfonate or primary alkyl sulfates surfactants conventionally used therein are replaced by secondary (2,3) alkyl sulfate surfactants. Thus, laundry detergent compositions comprising a secondary (2,3) alkyl sulfate, a source of calcium ions or magnesium ions, and one or more protease, cellulase, amylase, lipase, or peroxidase detergent enzymes are provided.
Il s'est avéré que des compositions détergentes contenant des enzymes et du calcium, ou des ions de magnésium, devenaient plus stables lorsque du benzènesulphonate d'alkyle ou des sulfates primaires d'alkyle traditionnellement utilisés comme tensioactifs étaient remplacés par des sulfates secondaires d'alkyle (2,3). L'invention porte donc sur des compositions détergentes pour le linge comprenant un sulfate secondaire d'alkyle (2,3), une source d'ions calciques ou d'ions de magnésium, et une ou plusieurs enzymes détergentes, telles que la protéase, la cellulase, l'amylase, la lipase ou la péroxidase.
