Title: POURABLE DETERGENT SUSPENSION COMPRISING BLEACH CATALYST GRANULES
Abstract:
The invention relates to a pourable detergent suspension comprising: - 30-80 wt.% of hygroscopic component selected from aminocarboxylate chelant, glycerol and combinations thereof; - 8-25 wt.% of water; - 1-30 wt.% of bleaching agent; - 0.1-5 wt.% wt.% of bleach catalyst granules having a diameter in the range of 20 to 2000 µm, said bleach catalyst granules comprising: - 30-90 wt.% of one or more core particles; - 10-70 wt.% of a coating that envelops the one or more core particles, said coating being composed of one or more coating layers and containing: - 1-30% by weight of the coating of catalyst particles containing at least 30 wt.% of manganese bleach catalyst; and - 50-99% by weight of the coating of water-soluble alkali metal sulfate salt; said bleach catalyst granules containing no enzyme, 0.3-20 wt.% of the catalyst particles and 30-99 wt.% of the water-soluble alkali metal sulfate salt. This pourable detergent suspension is easy to manufacture and exhibits good storage stability despite the fact that it contains bleaching agent, bleach catalyst and a significant amount of water.
