Abstract:
A method of manufacturing detergent composition, which method comprises:(i) combining the following components to form a blended mass: (a) about 20 to 80 wt % of an alkali metal carbonate; (b) about 1 wt % to 30 wt % of an organic phosphonate; (c) about 0.01 to 1.3 mole of water per mole of carbonate; and (d) at least one of bleaching agent and enzyme; and (ii) forming the blended mass into a composition comprising non-hydrated alkali metal carbonate and a binding agent comprising a mono-hydrated alkali metal carbonate and organic phosphonate, wherein the mole ratio of alkali metal carbonate to organic phosphonate in the binding agent is in range of about 3:1 to about 7:1 and the composition is substantially free of a source of alkalinity other than an alkali metal carbonate.
