  • Publication number: 20220071203
    Abstract: Low foaming, highly acidic peroxycarboxylic acid sanitizing compositions are disclosed as having both improved antimicrobial efficacy in comparison to conventional peroxyoctanoic acid and peroxyacetic acid compositions for sanitizing applications. The compositions include a combination of a low-foaming surfactant and an aluminum sulfate (or other metal salt) defoaming agent that is compatible with the highly acidic peroxycarboxylic acid sanitizing compositions. In particular, the sanitizing peroxycarboxylic acid compositions are also low odor and low/no VOC dual functioning acid wash and sanitizing compositions.

  • Patent number: 11241009
    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.
