Concentrated detergent powder compositions having a bulk density of above 600 g/l, preferably at least 610 g/l, more preferably from 650 g/l to 1200 g/l, and comprising a surfactant, a detergency builder, enzymes, a peroxygen compound bleach, and a manganese complex as effective bleach catalyst are disclosed. Specifically preferred manganese complexes are: 1) ¢MnIV2(.mu.-O)3(Me-TACN)2!(PF6)2 and 2) ¢MnIV2(.mu.-O)3(MeMe-TACN)2!(PF6)2 Use of these catalysts can make the detergent powder more compact, i.e. reduce the pack volume, without loss of performance or even with a much better bleaching and washing powder.
