Abstract
Machine dishwashing detergents containing a novel homogeneous blend of a conventional low-foaming nonionic surfactant and a second low foaming nonionic surfactant having relatively low cloud point unexpectedly provide effective detergency and result in dishes and other utensils being cleaned to a sparkling clean spot-free condition without the use of conventional phosphate ester defoamers such as monostearyl acid phosphate. The machine dishwashing detergent compositions of the invention are effective on dishes and other utensils encrusted with soils comprising egg and other milk-derived protein soils.
