ABSTRACT:
A non-phosphate machine dishwashing detergent composition comprising at least about 80 wt. % of a combination of alkaline carbonate, e.g., sodium carbonate, and alkaline bicarbonate, e.g., sodium bicarbonate, having a weight ratio of carbonate to bicarbonate of about 1:1 to 1:5, about 0.5 to 8.0 wt. % of a polycarboxylate polymer consisting of polymaleic acid as dispersant, and about 0.5 to 8.0 wt. % of a nonionic surfactant. The composition may also contain an oxygen bleach, e.g., sodium perborate, and an alkali metal silicate corrosion inhibitor, e.g., sodium silicate, as well as other additives. Use of the composition results in relatively low residue formation on articles being washed.
