Abstract

The use of acylated carbohydrates selected from the group consisting of sucrose, maltose, lactose, palatinose, trehalulose, glucose and fructose or mixtures of these as a detergent constituent is characterized in that these acylated carbohydrate compounds contain one or two carboxyl functions and are in the form of the mono- or diacid or an alkali metal salt thereof, wherein the acyl radical is selected from the group consisting of C1- to C18-alkyl, tolyl and benzyl radicals and can be identical or different, and are used as bleaching agent activators or complexing agents in detergent formulations, the acyl radical preferably being a methyl radical.
