Abstract
Alkaline built detergent bleach compositions are disclosed comprising a surface-active agent; a peroxide compound bleach; a manganese compound which delivers manganese (II) ions in aqueous solution (e.g. manganous sulphate or manganous chloride); and a builder mixture comprising a water-insoluble aluminosilicate ion-exchange material and an alkalimetal orthophosphate and/or an alkalimetal silicate. The composition is particularly effective for washing fabrics at lower temperatures, e.g. from 20.degree. to 60.degree. C., but is also usable at higher temperatures.
