ABSTRACT:
Machine dishwashing detergents are disclosed containing a low-foaming nonionic surfactant having relatively low cloud point which unexpectedly provides effective detergency, foam control and good rinsing action 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 especially in controlling foam on washing dishes and other utensils encrusted with soils generally encountered on dishes, specifically egg and milk-derived protein soils.
