ABSTRACT:
Automatic dishwashing detergent compositions comprising a mixed nonionic surfactant system comprising low cloud point and high cloud point nonionic surfactants. The low cloud point nonionic surfactant has the formula: CH.sub.2 CH(OH)R.sub.2
wherein R.sub.1 is a linear or branched, aliphatic hydrocarbon radical having from about 4 to about 18 carbon atoms; R.sub.2 is a linear or branched aliphatic hydrocarbon radical having from about 2 to about 26 carbon atoms; x is an integer having an average value of from 0.5 to about 1.5; and y is an integer having a value of least about 15. The high cloud point nonionic surfactant comprises an ethoxylated surfactant derived from the reaction of a monohydroxy alcohol containing from about 10 to about 16 carbon atoms, with from about 6 to about 15 moles of ethylene oxide per mole of alcohol on an average basis and having a hydrophile-lipophile balance value within the range of from about 12 to about 14.
