Abstract: Activated hydrogen peroxide disinfecting compositions are provided especially for low-foaming applications. A concentrate for dilution by an end-user is provided, which includes a hydrogen peroxide source, a non-surfactant organic sulfonic acid or salt thereof, a non-ionic surfactant, and an optional organic acid. Also provided is a ready-to-use hydrogen peroxide, disinfectant solution including a biocidal amount of hydrogen peroxide, a non-surfactant organic sulfonic acid or salt thereof, a non-ionic surfactant, water as solvent and an optional organic acid. An end-user can disinfect a surface of microorganisms by contacting the surface with the disinfecting composition for an amount of time effective to kill a majority of the microbes located on the surface.
Abstract: The present invention relates to a disinfecting composition which requires a shorter contact time to be effective than similar compositions. Also, provided is a method of disinfecting a surface with the disinfecting composition where a shorter contact time is needed to disinfect the surface.
Abstract: A wiping composition and a wiping product containing the composition are disclosed. The wiping composition contains a combination of an antimicrobial agent with a preservative enhancing agent that not only provides antiseptic properties when applied to an adjacent surface, but also is well suited to preserving the substrate that is used to apply the composition. In particular, the composition has been unexpectedly found to inhibit or destroy bacteria, particularly Burkholderia cepacia, even when the active ingredients are used at extremely low levels.

Abstract: A kit and method for accurately determining the concentration levels of peracetic acid in a solution containing a peroxide or other oxidant is disclosed. In order to determine the concentration of peracetic acid in the solution, a pH buffer system is used to deactivate high levels of a peroxide in a disinfectant solution without interfering with active peracetic acid levels in the solution. At least one test strip is used to measure the peracetic acid concentration in the solution. A test vial for combining the solution with the pH buffer prior to contact with the test strip is provided.

Abstract: A composition having biocidal properties is disclosed. The composition includes a biocide in combination with a film forming component. In one embodiment, for instance, the biocide comprises an amine while the film forming component comprises one or more polyvinyl alcohol polymers. The disinfectant composition forms a film on a surface that is abrasion resistant and will provide biocidal activity over an extended period of time, while being completely water dispersible.
