Chris Nagel 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: 12290071
    Abstract: Peroxyformic acid compositions for removal of biofilm growth and other contaminants and impurities from industrial processing hard surfaces are disclosed. In particular, peroxyformic acid compositions may be dosed on site and/or generated in situ for the reduction and prevention of biofilms on the hard surfaces. Methods of employing the peroxyformic acid compositions for removal of biofilm growth and other impurities such as aldehydes and alcohols from industrial CO2 effluent are also disclosed which beneficially provide ambient biofilm control and break down more rapidly than other peracids, allowing for extended runs between CIP cleaning, including a reduction and/or elimination of cleaning of the scrubbers and other industrial surfaces.

  • Publication number: 20250084350
    Abstract: The invention discloses cleaning compositions which employ a synergistic combination of an ester solvent, preferably a fatty acid methyl ester in combination with one or more linear alkyl amines. The alkyl amines act as to remove and suspend organic oils which have been burnt or adhered to a surface with heat and may even be used alone as a soil removal agent. The cleaning compositions have particular use in cleaning of distillation towers associated with biofuel, and vegetable oil refining, but also find use in cleaning ovens, food cooking surfaces and even dry cleaning.

  • Patent number: 12241046
    Abstract: Stabilized peroxide-containing compositions stabilized with urea and urea/chelator stabilizer blends are provided. The compositions are particularly suitable for, but not limited to, cleaning applications on surfaces within food and beverage industries which may require the use of materials that are acceptable for incidental food/food products/feed contact. Further, the stabilized compositions are particularly suitable for applications requiring materials that are generally regarded as safe (GRAS) or for applications where non-GRAS materials must be minimized. Methods of stabilizing peroxide-containing compositions and methods of using the compositions are also provided.

  • Publication number: 20240415116
    Abstract: Stabilized peroxycarboxylic acid compositions and the solid supported peracid stabilizers are provided. Methods of producing the solid supported peracid stabilizers are provided. The solid supported peracid stabilizers and the stable peroxycarboxylic acid compositions are particularly suitable for use in sanitizing equipment and surfaces to reduce yeasts, spores and bacteria, including those having contact with food, food products and/or components thereof, which require or benefit from infection control suitable for direct contact with such food sources.
