Abstract
A C.sub.1-4 alkyl-di C.sub.6-20 alkylamine oxide surfactant composition can be used in detersive systems. The amine oxide can be used in effective surfactant concentrations in aqueous alkaline solutions (pH about 7 or greater) producing an aqueous solution having halogen stability, reduced surface tension and low foaming properties. The surfactants have properties that are useful in detersive systems for hard surfaces, warewashing, laundry, clean-in-place, and other applications.
