ABSTRACT:
A thickened aqueous cleaning composition is viscoelastic, with a long relaxation time to provide a thick solution with consumer-acceptable pour properties. The composition has utility as a drain opening composition or as a hard surface cleaner having a cleaning-effective residence time on non-horizontal surfaces. The composition includes a cleaning active, and a binary thickener comprising a betaine or sulfobetaine having a C.sub.14-18 alkyl, or C.sub.10-18 alkylamino or alkylamido group, and an organic, anionic counterion. The composition preferably has a relaxation time of at least about 5 seconds and a relative elasticity between about 10-500 sec/Pa.
