Abstract:
An aqueous alkaline warewashing detergent use solution consisting essentially of, in a aqueous medium:(a) an effective soil removing amount of a source of alkalinity to provide the detergent with a pH of at least 10.0 when provided as a 1 wt. % aqueous solution; and (b) an effective soil removing amount of a nonionic surfactant blend comprising: (i) a nonionic surfactant comprising a hydrophobic group and an (EO)x group, wherein x is a number of about 1 to 100; and ii) a nonionic silicone surfactant having the formula: wherein x represents a number that ranges from about 0 to about 100, y represent a number that ranges from about 1 to about 100, a represents a number from about 0 to about 12, b represents a number from about 0 to about 60, and wherein a+b&gE;1 and R is hydrogen or a lower (C1-6) alkyl.wherein the blend of nonionic surfactants is present in the use solution in an amount up to about 40 parts by wright of the nonionic surfactant blend per each one million parts of the use solution, said use solution exhibits enhanced waxy-fatty soil removing capacity from the surface of ware and said use solution exhibits a surface tension of less than about 35 dynes/cm at a temperature of 160Â° F. to achieve soil removal.
