  • Granular composition
    Patent number: 6911423
    Abstract: In order to improve the dispersion of nonionic surfactant into wash water from a granule in which the nonionic surfactant is carried on a water-insoluble granular material, the nonionic surfactant is intimately mixed with a structurant which is a non-soap ionic surfactant in finely divided particulate form. A preferred structurant is an anionic surfactant, for example, primary alcohol sulphate.
    Type: Grant

  • Anti-form system based on hydrocarbon polymers and hydrophobic particulate solids
    Patent number: 5695575
    Abstract: A method and composition for inhibiting foam formation in automatic dishwashers are described. The composition comprises an anti-foam system having 0.01 to 1% of certain hydrophobic particulate solids combined with 0.01 to 4% of high viscosity hydrocarbon polymers; 1 to 30 wt. % of a bleaching agent; 1 to 40 wt. % of a surfactant; 0.1 to 10 wt. % of an enzyme; and 1 to 75 wt. % of a builder, the composition having a pH of less than about 11.
