Abstract

The invention concerns a particularly simple and economical process for preparing particulate washing and/or cleaning agents, whereby both bleach and enzymes can be incorporated in these agents without the activity of these constituents decreasing by an unreasonable extent either during preparation or during subsequent storage. This object is essentially achieved in that a peroxygenated oxidizing agent component, optionally in the presence of inert solids, is granulated or compacted in a granulation mixer or compactor using water and liquid non-ionic surfactant as granulation liquid, and is then mixed with the particulate enzyme component and optionally further particulate constituents.
