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.

Abstract: The present invention is based upon the discovery that a low-phosphate automatic dishwashing composition comprising from about 2.0 to 50.0 percent by weight of alkali metal carbonate salts such that it contains a weight ratio of about 1:1 to 20:1 carbonate to bicarbonate, from about 2.0 to 60.0 percent by weight of a water-soluble organic complexing agent comprising one or more hydroxycarboxylic acids or the salts thereof, a sufficient amount of an alkaline condensed phosphate salt to provide from about 0.1 to 1.7 percent by weight of (P.sub.2 O.sub.5) ion, from about 0.5 to 8.0 percent by weight of about a 2:1 to a 6:1 blend of an acrylic polymer comprising a salt or ester of acrylic or methacrylic acid having a molecular weight of between about 1,000 to 25,000, with a copolymer of a substituted or unsubstituted maleic anhydride and lower olefin having a molecular weight of from about 1,000 to 50,000, and from about 0.5 to 8.

Abstract: The present invention is based upon the discovery that high levels of carbonate salts can be formulated with minor concentrations of phosphates (e.g., about 0.1 to 0.3 percent by weight as expressed as (P.sub.2 O.sub.5) together with low levels of a mixture of certain polycarboxylate homopolymers and copolymers (i.e., in combination, a total of about 0.5 to 8.0 percent by weight), and relatively high levels of nonionic surfactants in a dishwashing detergent formulation while providing satisfactory cleaning without unacceptable spotting and filming and without the need to add a chlorinating agent.
