Patents by Inventor David Dotzauer

David Dotzauer 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.

  • Patent number: 11920109
    Abstract: Detergent compositions and methods of preparing and using the detergent compositions are disclosed. The detergent compositions comprise a polymer system comprising at least one polycarboxylic acid polymer, copolymer, or terpolymer, an alkalinity source comprising an alkali metal carbonate, a nonionic surfactant and water. The detergent compositions are suitable at alkaline pH and reduce or prevent scale formation, improve soil dispersion, and provide effective detergency.

  • Patent number: 11731889
    Abstract: Stabilized compositions employing a sequestrant system and a binding system for improving shelf stability and dispensing stability of a solid activated bleach composition are disclosed. The compositions contain a peroxygen source and a catalyst activator which require generation of a peroxycarboxylic acid or other active oxygen sanitizing agent at a point of use. Stabilized compositions employ a sequestrant system including a phosphonic acid and/or dipicolinic acid sequestrant and a binding system comprising an anionic surfactant for a solid formulation of a catalyst activator and peroxygen source to provide shelf stability and dispensing stability for a activated bleach composition. Methods of formulating and use are further disclosed.
