Abstract
Disclosed are detergent compositions comprising a suds inhibiting amount of a synergistic antifoaming combination, and preferably further comprising a high-sudsing surfactant such as an amine oxide surfactant. The antifoaming combination consists of a carboxylated poly(oxyalkylated) alcohol cosurfactant and a silicone antifoaming agent in a weight ratio of from about 1:50 to about 1000:1. Both individual elements of the antifoaming combination are known. The carboxylated poly(oxyalkylated) alcohol has the formula ##STR1## wherein R is a hydrocarbon-containing group having from about 6 to about 18 carbon atoms; each R' is independently selected from the group of hydrogen, methyl and carboxylic acid-containing groups having from 1 to 6 carbon atoms wherein the cosurfactant contains at least one such carboxylic acid-containing group; M is selected from the group of hydrogen and sulfate; x is a number from about 3 to about 75.
