The invention relates to a bleach catalyst granules containing a metal-containing bleach catalyst, which comprises at least one ligand selected from the group comprising di- or trimethyltriazcyclononanes or derivatives therefrom, and a homo- or copolymer polycarboxylate, salts thereof or partially neutralized having a pH-value of between 3 and 9. Said granules are produced in an anhydrous granulation process, in particular by compacting, the treatment temperature being maintained at below 100&#xb0; C.

Bleach catalyst granules, use thereof and washing cleaning agents containing the same

The invention relates to a bleaching-agent co-granule containing a bleach activator, a metal-containing bleach catalyst comprising at least one ligand from the group consisting of di- or trimethyltriazacyclononane and derivatives of these, and a homo- or copolymeric polycarboxylate or its salts or partial neutralizates having a pH in the range from 3 to 9. The bleaching-agent co-granule is obtained in an anhydrous granulating process, preferably by compaction at a temperature below 100&#xb0; C. The invention also relates to the method of using the bleaching-agent co-granule in dishwasher detergents and to a detergent comprising said bleaching-agent co-granule.

Bleaching-agent co-granules, method for producing said bleaching-agent co-granules, and use of said bleaching-agent co-granules

The invention relates to co-granules containing a) at least one bleach activator, b) at least one metal-containing bleach catalyst, and c) at least 5 wt. % of at least one organic acid. The co-granules are easy to produce, have a high stability in storage and are advantageously suitable for producing cleaning products and detergents and especially products for cleaning crockery in a machine.

Bleach granules

The invention relates to co-granules containing a granule core and a sheath or coating layer surrounding the granule core. Said co-granules are characterized in that the granule core contains a) at least one bleach activator, a2) between 0 and 20 wt. % of the total quantity of at least one bleach catalyst contained in the co-granule, and c) at least one binding agent, and the sheath or coating layer contains d) between 80 and 100 wt. % of the total quantity of the at least one bleach catalyst contained in the co-granule, and e) at least one coating agent. The co-granules are advantageously suitable for producing cleaning products and detergents and especially products for washing crockery in a machine.
