| abstract |
A particulate detergent composition contains a sequestrant which is iminodisuccinate (IDS) or hydroxyiminodisuccinate (HIDS), in the form of a calcium or magnesium complex, the molar ratio of calcium or magnesium ion to (H) IDS being at least 2:1. The complex has significantly lower hygroscopicity than sodium (H) IDS. The composition is preferably a laundry detergent composition in the form of a powder, especially a compact powder, or a tablet. |
