Bleach Catalyst Granules, Use Thereof and Washing Cleaning Agents Containing the Same

摘要

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.

主权项

1. A bleach catalyst granule containing 0.01 to 50 wt %, relative to the overall weight of the granule, of a metal-containing bleach catalyst comprising at least one ligand from the group consisting of di- or trimethyltriazacyclononanes or derivatives thereof, and 50 to 99.9 wt %, relative to the overall weight of the granule, of a homo- or copolymer of (meth)acrylic acid or its salts or partial neutralizates having a pH between 3 and 9, as measured on a 1 wt % solution in water, characterized in that it is obtained in an anhydrous granulating process, wherein the processing temperature is maintained below 100° C.
