ABSTRACT:
Machine dishwashing detergents are disclosed containing a low-foaming nonionic surfactant having relatively low cloud point which unexpectedly provides effective detergency and foam control when utilized as the sole nonionic surfactant. Dishes and other utensils are cleaned to a sparkling clean spot-free condition by the machine dishwashing detergent compositions of the invention containing conventional phosphate builders or non-phosphate builders but excluding conventional alkyl phosphate ester defoaming agents. 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.
