Abstract: The invention relates to a process for providing piroctone olamine granules having a target particle size range, comprising: a) Compressing piroctone olamine crystals to form a compactate; b) Milling the compactate to form bulk granules of piroctone olamine.

Abstract: 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° C.

Abstract: 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° 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.
