Abstract: The rinsing performance of acidic gel cleaners comprising acid, surfactant and water is improved using a synergistic combination of two polymers consisting essentially of (a) copolymer having a quaternized monomer and (b) microbially-derived polysaccharide. In a preferred embodiment of the invention, the acidic gel cleaner includes (a) a copolymer having at least a diallyldimethylammonium chloride monomer or an acrylamidopropyltrimethylammonium chloride monomer, and (b) xanthan gum. The improved gel cleaners have the unique ability to be easily rinsed from a hard surface even if previously dried into a dry mass on the hard surface.

Abstract: An improved liquid abrasive cleanser is described that shows greatly improved soil removal performance along with improved rinsing characteristics. The improved cleanser is comprised of abrasives, silica, at least one surfactant, an associative polymer thickener, a pH adjusting agent and water. The compositions of the present invention show pseudo-plastic rheology in that they shear thin upon dispensing through a bottle closure, but re-thicken on hard surfaces to provide vertical cling.
