Concentrated detergent powder compositions

Claim 1

A concentrated detergent powder composition having a bulk density of above 600 g/l, preferably at least 610 g/l, comprising: (a) from 10 to 50%, preferably from 15 to 40% by weight, of a surface-active agent, selected from the group consisting of anionic, nonionic, cationic and amphoteric surfactants, and mixtures thereof; (b) from 15 to 80%, preferably from 20 to 70% by weight, of a detergency builder or builder mixture; (c) from 0 to 10%, preferably from 0.001 to 10% by weight, of an enzyme; (d) from 5 to 35%, preferably from 10 to 25% by weight, of a peroxygen compound, characterized in that the composition further contains from 0.0005 to 0.12%, preferably from 0.001 to 0.05% by weight, of manganese in the form of a manganese complex as bleach catalyst of the following formula: wherein Mn is manganese, which can be either in the II, III or IV oxidation state; X 1 , X 2 and X 3 represent a bridging species selected from O, O 2 , HO 2 , OH, ROCOO and RCOO ions and mixtures thereof, with R being H, C 1 -C 4 alkyl; z denotes the charge of the complex which can be positive or negative. If z is positive, Y is a counter-anion such as Cl - , Br - , I - , NO 3 - , ClO 4 - , NCS - , PF 6 - , RSO 3 - , RSO 4 - or OAc - , wherein R can be H or C 1 -C 4 alkyl; if z is negative, Y is a counter-cation which can be an alkali metal, alkaline earth metal or (alkyl) ammonium cation; q = z/charge Y; and L is a ligand which is an organic compound selected from N, N′,N˝-trimethyl-triazacyclononane (Me-TACN) and its carbon-substituted derivatives having the formula: wherein R 1 -R 6 can each be hydrogen or a C 1 -C 4 alkyl group.
