  • Patent number: 4005030
    Abstract: A detergent composition containing an anionic detergent and an organosilane is capable of imparting soil release benefits to hard surfaces washed therewith. Soil adheres to such surfaces less strongly thereby making them easier to clean. The detergent composition can be formulated for use in a wide range of applications, e.g., as a light duty liquid composition, car wash composition, oven cleaner, window cleaner or toilet bowl cleaner.

  • Patent number: 4001132
    Abstract: Bleach-free granular detergent compositions for use in automatic dishwashers comprising an alkoxylated nonionic surface-active agent, a sulfonated aromatic compatibilizing agent and a mixture of an alkali sulfite and an alkali sulfate in a specific weight ratio. Preferred nonionic surfactants include ethoxylated nonionics and preferred compatibilizing agents can be selected from xylene-, toluene-, cumene-, benzene-, trimethyl benzene-, ethylbenzene- and ethylmethyl benzenesulfonates. The sulfite-sulfate mixture is present in a weight ratio of sulfite to sulfate from about 1:4 to about 2:1. The instant compositions possess enhanced anti-redeposition properties for soils composed of grease and grease-protein complexes and, in addition, exhibit improved cleaning properties particularly for burned-on soils.
