    Inventors: David C. Heckert, David M. Watt, Jr.
  • Patent number: 4005024
    Abstract: A rinse aid composition containing an organosilane and a low molecular weight monofunctional organic acid is capable of imparting soil release benefits to cooking utensils and tableware rinsed therewith. Food soils adhere to such surfaces less strongly, thereby making them easier to clean. The inclusion of the monofunctional organic acid insures that objectionable spotting or filming does not form on the rinsed objects.

  • 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.
