Abstract

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.
