Abstract
A thickened aqueous cleaning composition is viscoelastic, and has utility as a drain opening composition or as a hard surface cleaner having a cleaning-effective residence time on non-horizontal surfaces. In one embodiment the composition comprises a cleaning active, a quaternary ammonium compound, and an organic counterion. In another embodiment, the viscoelastic quality of the composition is advantageously utilized as a drain opener which rapidly penetrates standing water with minimal dilution to deliver active to the clog material.
