Patent ID: 8772217

Claim:
An alkaline hard surface cleaning composition having a pH of at least 10.5 which composition comprises a cleaning effective amount of an amine oxide surfactant constituent which amine oxide surfactant is the sole detersive surfactant present in the composition and wherein the composition is essentially free of cosurfactants; an alkanolamine constituent; a phenyl containing glycol ether solvent which is the sole organic solvent present in the composition: an antimicrobially active constituent; water; and, further optionally, minor amounts of one or more constituents which improve one or more aesthetic or functional characteristics of the inventive compositions; wherein the composition excludes cosolvents selected from alcohols, glycols, water-miscible ethers, water-miscible glycol ethers, lower esters of monoalkylethers of ethylene glycol or propylene glycol, glycol ether having the general structure Ra-Ob-OH wherein Ra is an alkoxy of 1-20 carbon atoms and Rb is an ether condensate of propylene glycol and/or ethylene glycol having from one to ten glycol monomer units.
