all during the wash cycle of an automatic dishwashing appliance in addition a low foaming nonionic surfactant can function to suppress foaming during the wash cycle caused by food residues examples of nonionic surfactants include without limitation various condensation products for example the condensation product from a mixture of about one mole of a fatty alcohol or fatty acid and about four to about forty moles of ethylene oxide can be used the fatty alcohol or fatty acid can be saturated or unsaturated while the chain can be straight or branched in addition the chain can contain from ten to twenty carbon atoms another nonionic surfactant can be the condensation product from a mixture of about one mole of alkyl phenol and about four to about fifty moles of ethylene oxide the alkyl chain of the alkyl phenol can contain from eight to eighteen carbon atoms further polyoxypropylene polyoxyethylene condensates can be used as nonionic surfactants polyoxypropylene polyoxyethylene condensates can have a chemical formula of r 1 o ch 2 ch 2 o x ch ch 3 ch 2 o y r 2 where ri can be h or an alkyl group having from one to four carbon atoms where r 2 can be h or an alkyl group having from one to four carbon atoms where x is an integer greater than or equal to one where y is an integer greater than or equal to one and where the total c 2.
