Pulverulent or water-free liquid detergents each essentially contain surfactants, builders, bleaching agents and effective amounts of compounds of the formula ##STR1## where R.sup.1 is for example C.sub.1 -C.sub.8 -alkyl, substituted or unsubstituted alkyl or C.sub.3 -C.sub.8 -alkenyl, and R.sup.2 and R.sup.3 are each for example H or C.sub.1 -C.sub.16 -alkyl, as bleach activators for peroxides.
