  • Patent number: 3983079
    Abstract: A granular, agglomerated, powdered or liquid detergent composition comprising a surface-active quaternary ammonium compound, a slightly water-soluble nonionic polypropylene oxide-polyethylene oxide condensation product, and either a surface-active betaine or a sultaine. The detergent composition is designed particularly for washing glassware, china, and glazed or vitreous articles. It provides not only good cleaning, especially fat removal and suspension, but also imparts to the washed articles persistent rinse water drainage characteristics which substantially minimize the filming, streaking, spotting of the washed, rinsed and air-dried articles.
