  • Patent number: 7202200
    Abstract: The invention provides an improved, liquid aqueous hard surface cleaner containing a fluoropolymer having a molecular weight of no less than 5,000, further containing preferably a nonionic surfactant, optionally, a quaternary ammonium compound, a chelating agent/buffer and water to provide enhanced cleaning of hard surfaces, especially vitreous surfaces, in which the thus cleaned surface is rendered soil and stain repellent.

  • Patent number: 6294511
    Abstract: The present invention provides an abrasive-free cleaning composition which includes, in aqueous solution, a bleach, a colloidal thickener, and a source of divalent ionic calcium. The composition further includes at least one surfactant which is effective to provide cleaning activity and, in association with the colloidal thickener, thickening. The composition also includes an electrolyte/buffer which is effective to promote an environment in which the thickener and the surfactant associate to provide proper thickening. The inventive cleaning composition, with its ionic calcium source, has desirable viscosity and rheological properties, and demonstrates significant viscosity stability, rheological stability, phase stability and bleach stability. The cleaning composition maintains these desirable properties under typical storage conditions as well as over extended times and at elevated temperatures.

  • Patent number: 5854187
    Abstract: The invention provides a concentrated, dilutable cleaning composition which comprises a novel microemulsion comprising a nonionic surfactant oil phase, a predominant, aqueous continuous phase, a polar organic solvent coupling agent, and a combination of surfactants different from the surfactant oil phase as the dispersing agent facilitating formation of the microemulsion.
