Non-phosphate machine dishwashing detergents

摘要

The present invention is based upon the discovery that high levels of carbonate salts can be formulated 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 phosphates and/or a chlorinating agent.
