1-16. (canceled).
A dishwash detergent, wherein the detergent is a tablet comprising two or more layers, and wherein the tablet comprises:
- (I) a detergent enzyme granule, and
- (II) a non-enzymatic granule comprising:
- (a) a core particle having a diameter of 250-1200 μm, surrounded by
- (b) a first coating which comprises bleach catalyst particles and a binder, which is surrounded by
- (c) a second coating comprising at least 80% by weight of the coating of a water-soluble salt selected from the group consisting of Na2CO3, Na2SO4, K2SO4, KHSO4, MgSO4, sodium citrate, and combinations thereof, which is surrounded by
- (d) a third coating comprising polyethylene glycol or polyvinyl alcohol;
- wherein the amount of bleach catalyst in the first coating is in the range of 2 to 15% by weight of the core;
- wherein the amount of binder in the first coating is in the range of 1 to 20% by weight of the core;
- wherein the combined second and third coating makes up at least 30% by weight of the core;
- and
- wherein the bleach catalyst particles comprise at least 80% by weight of a manganese complex comprising a ligand selected from the group consisting of triazacyclononane, dimethyl triazacyclononane, and trimethyl triazacyclononane, characterized in that the bleach catalyst particles have a volume average particle size D97 in the range of 10 to 30 μm.
