  • Patent number: 5470499
    Abstract: The invention is a hard surface abrasive scouring cleanser having no significant syneresis, undue viscosity or yield stress increase, stably suspends abrasives, and has excellent rinsing characteristics. Furthermore, the present invention provides a stably suspended abrasive scouring cleanser which uses relatively small amounts of surfactants, thus lowering the total cost of producing these cleansers. The lesser amount of surfactant also affords the cleanser a milder feel and lower unaesthetic surfactant odor, while also requiring lower levels of fragrance. The absence of solvents results in a less irritating product as well.In one aspect the invention comprises, in aqueous solution:(a) a cross-linked polyacrylate;(b) at least one nonionic surfactant;(c) a pH adjusting agent; and(d) a calcium carbonate abrasive.

  • Patent number: 5376297
    Abstract: This invention provides a thickened aqueous hard surface cleaner composition comprising colloidal alumina as the thickener in an aqueous cleaner which comprises a surfactant, electrolyte/buffer, soap and organic solvent system. These cleaner composition systems, which are the fluent, all-purpose type of cleaners, have surprising properties when thickened with the colloidal alumina. Such cleaners when thickened with colloidal alumina have a smoothly flowable or plastic consistency, and in their most preferred form, are pourable at room temperature, which consistency is not thixotropic in nature.

  • Patent number: 5336426
    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. In these embodiments and corresponding methods of use, a free amine is limited with respect to the amount of the quaternary ammonium compound in the composition in order to maintain phase stability and to achieve further enhanced rheological and aesthetic properties in the composition.

  • Patent number: 5298181
    Abstract: This invention provides a thickened aqueous hard surface abrasive scouring cleanser having improved cleaning efficacy due to the presence of an organic solvent in the composition. It has surprisingly been found that an organic solvent can be included in an abrasive, surfactant, electrolyte/buffer, soap and colloidal alumina thickened composition without causing the system to become unstable. The abrasive cleanser of this invention has a smoothly flowable or plastic, preferably pourable, consistency and has stable abrasive-suspension characteristics over long periods of time.
