Abstract
An additive composition which can be adapted into conventional automatic dishwasher detergents for reducing foam during use thereof, comprising: A. a nonionic surface active agent having the formula: ##STR1## wherein R is a substantially linear, alkyl radical having an average from about 6 to about 12 carbon atoms, R' is a linear, alkyl radical of 1 to about 4 carbon atoms, R" is a linear, alkyl radical of 1 to about 4 carbon atoms, x is an integer of 1 to about 6, y is an integer of about 4 to about 20, and z is an integer of about 4 to about 25, and B. an alkyl phosphate ester having an average of 16 to 28 carbon atoms in the alkyl radical; and Wherein the weight ratio of (A):(B) is from about 1:1 to about 99:1.
