Patents by Inventor Lisa M. Sanders

Lisa M. Sanders has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11959050
    Abstract: The invention includes ware detergent compositions which provides superior cleaning and removal of oily and fatty soils, without the production of excessive foam. According to the invention applicants have discovered that use of a quaternary cationic surfactant in combination with a nonionic low foaming surfactant can provide oily soil removal from ware that is superior to traditional warewash detergent formulations. Compositions for alkaline, preferably solid, warewash detergents are disclosed, as well as their use in dish machines and methods of manufacture.
