Concentrated detergent powder compositions are disclosed having a bulk density of above 600 g/l, and comprising a surfactant, a detergency builder, a peroxy bleach compound, and a specific type of dinuclear manganese complex as effective bleach catalyst. A particularly preferred dinuclear manganese complex is: [(Et-bridged(Me2TACN)2)Mn<III>Mn<IV>( mu -0)2( mu -OAc)]<2+>(PF6<->)2. Said bleach catalyst was found to exhibit favourable storage stability in a concentrated detergent powder composition according to the invention. |
