  • Publication number: 20230183615
    Abstract: A disinfecting, sanitizing and cleaning composition is a formulation that is safe for use on food contact surfaces without the need for any post-application water rinse. In one exemplary embodiment, the cleaning and disinfecting composition eliminates the need for the post-application water rinse by using only components that are considered Food Safe by the EPA. In another exemplary embodiment, the cleaning and disinfecting composition the includes citric acid, but without any anionic surfactants in the cleaning and disinfecting composition. In still another exemplary embodiment of the disclosure, the cleaning and disinfecting composition includes a second organic acid and one or more nonionic surfactants as components along with citric acid to provide unexpected and beneficial antimicrobial properties to the cleaning and disinfecting composition.
