  • Publication number: 20140271762
    Abstract: A disinfectant wipe is provided including a substrate that is substantially free of polyamides, and an acid anionic disinfectant is adsorbed to the substrate such that the disinfectant readily releases from the substrate to allow at least 65% delivery of the disinfectant when wiped on a surface. The substrate may be a woven, nonwoven, knit fabric, a foam, sponge or film composition and may be formed from polyester, polypropylene, nylon, cotton, rayon, acrylic, or combinations thereof. The acid anionic disinfectant has a pH below 7, below 5, below 3 and below 2. The substrate used to prepare the disinfectant wipe is not pretreated with the disinfectant or a release composition before applying the disinfectant. That is, the disinfectant is not applied and re-applied to ensure release onto a surface. In an embodiment of the invention acid anionic disinfectant is an antimicrobial agent.

  • Publication number: 20140255514
    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.
