Low-foaming warewash detergent containing mixed cationic / nonionic surfactant system for enhanced oily soil removal

A warewash alkaline detergent composition comprising:

• from about 40 wt. % to about 90 wt. % of an alkalinity source;
• from about 1 wt. % to about 20 wt. % of a surfactant component comprising a nonionic low foaming surfactant represented by the formula:
• RO—(PO)x(EO)y(PO)xH, wherein R is C8-18 alkyl, PO is propylene oxide;
• EO is ethylene oxide;
• x is 1-8 and y is 1-20, and a cationic quaternary surfactant represented by the formula:
• wherein R represents a C8-C18 alkyl or alkenyl;
• R1 and R2 are C1-C4 alkyl groups;
• n is 10-25;
• and x is an anion selected from a halide or methyl sulfate, said surfactants in a ratio of greater than 1:1;
• from about 0.1 wt. % to about 10 wt. % of a defoaming nonionic surfactant;
• and
• one or more of a metal protector, water conditioning agent or polymer, an enzyme, a chelant, a bleaching agent, a solidification aid, and/or a carrier.
