Abstract
Abstract Built detergent bleach compositions having improved low temperature bleach performance comprising a sequestrant builder; a peroxyacid selected from peracetic acid, monoperoxyphthalic acid and monopersulphate and water soluble salts thereof; and 0.005 to 0.1% by weight of Manganese (II) ions, in the substantial absence of hydrogen peroxide. The compositions can be used for washing and cleaning fabrics at temperatures below 40° C.
