Abstract
Built detergent bleach compositions are disclosed comprising a surface-active agent, a peroxide compound bleach (e.g. sodium perborate), a manganese compound which delivers manganese (II) ions in aqueous solution (e.g. manganous sulphate or manganous chloride) and a builder mixture comprising a condensed phosphate and an alkalimetal orthophosphate in a weight ratio of from 10:1 to 1:60, preferably from 5:1 to 1:30. The composition is particularly effective for washing fabrics at low temperature, e.g. from 20.degree.-60.degree. C., but is also usable at higher temperatures.
