<p>Particulate detergent components comprising a bleaching agent and detergent compositions containing them are described. The invention relates to the problem of localised build-up of bleaching components and provides bleaching granules comprising no more than 50 wt.% of a particulate bleach component selected from bleach activators, pre-formed peracids, bleach catalysts and mixtures thereof, in addition to further detergent ingredients. The geometric mean particle diameter of the particulate bleach component is below 500νm. A method for making a bleach granule comprises in a mixing step, mixing the particulate bleach component with builders and/or surfactants and optionally other detergent ingredients and/or fillers in a high, moderate or low shear mixer to produce the bleach granules. Preferably, the bleach granules are produced in a moderate to low shear mixer.</p> |
