Abstract: Detergent compositions containing amide substituted peroxyacid bleaching compounds are provided in which at least 60% of the originally added peronacid bleach remains after 28 days storage at 32.degree. C. and 80.degree. RH. The compositions contain at least one multi-ingredient component and have a density in excess of 650 g/liter, a total Iron, Manganese and Copper content of less than 40 ppm, an Equilibrium Relative Humidity at 32.degree. C. of less than 30% and preferably a sodium sulphate content of less than 2.5 % by weight.

Abstract: Detergent compositions containing sodium percarbonate bleach are provided in which at least 60% of the originally added percarbonate remains after 28 days storage at 32.degree. C. and 80.degree. RH. The compositions contain at least one multi-ingredient component and have a density in excess of 650 g/liter, a content of Iron, Manganese and Copper less than 25 ppm, an Equilibrium Relative Humidity at 32.degree. C. of less than 30% and preferably a sodium sulfate content of less than 2.5% by weight.

Abstract: Solid Peroxyacid bleach precursor compositions are provided in which the external surfaces of a particulate peroxyacid precursor material is treated with from 2% to 20% by weight of a solid organic acid compound of Mpt>30.degree. C. and an aqueous solubility of at least 20 g/100 g water at 20.degree. C. The bleach precursor material, when so treated, perhydrolyses after 3 minutes in a standard test at 20.degree. C., to at least 90% of the extent of the untreated bleach precursor material under the same conditions. Preferred organic acid compounds are monomeric aliphatic hydroxycarboxylic and polycarboxylic acids such as citric, lactic and glycolic acids. Detergent compositions containing the treated peroxyacid bleach precursor particulates are also disclosed.
