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: It has now been discovered that a shaped article containing calcium hypochlorite has low reactivity in handling, storage and transportation as well as has a favorable dissolution (solubility) profile, when the shaped article contains lime and a hydrated magnesium sulfate. The shaped article has a NFPA rating of Class 1 oxidizer and is a non-Division 5.1 oxidizer.

Abstract: The present invention provides a quaternary ammonium etidronate compound (QAE) comprising a quaternary ammonium cation and an etidronate anion, having the Formula I. A method for the preparation of such compounds is described by reacting a quaternary ammonium salt with an etidronic acid or salt thereof. Variable ratios of each reactant may also be used to form different QAE compounds. The quaternary ammonium etidronate compounds is useful in water treatment, cosmetic, hygiene, personal care, paint, coating, wood treatment, agrochemical, antimicrobial, disinfectant, or biocidal compositions; as the compound provides high anti-corrosive and biocidal properties; and low scaling properties. A water treatment composition is also described, having a QAE compound of Formula I and a water treating biocidal agent, useful in cooling towers and other recirculating water, or recreational water system.

Abstract: The present invention relates to a stabilized water treatment composition, containing (i) an effective amount of a hydrogen peroxide source, (ii) a first stabilizing agent, and (iii) a second stabilizing agent; which is essentially free of any peracid-based compounds, derivatives or salts thereof. A method for the using the stabilized water treatment composition to kill or to inhibit the growth of microorganisms such as gram positive or gram negative bacteria, algae, cyanobacteria, viruses, fungi, mildew, mold or combinations thereof, for various water sources such as streams, ponds, lakes, recirculating water systems, surface water, and any other suitable or desirable water sources is also described.

Abstract: Disinfectant compositions disclosed herein comprise at least one biocidal quaternary ammonium compound, hydrogen peroxide, and optionally inorganic acid and/or organic acid. Particularly, a composition comprising a biocidal quaternary ammonium chloride compound, hydrogen peroxide, and C1 to C8 carboxylic acid, mono-, di- and tricarboxylic acid enhances significantly its antimicrobial activities of either hydrogen peroxide or the quaternary ammonium chloride alone.

Abstract: A biocide contains a hydrogen peroxide producing compound, in combination with controlled amounts of a chelating agent and a peroxide enhancing agent. In one embodiment, the composition can be used to control an algae population in a water body. The chelating agent and the peroxide enhancing agent synergistically combine with the hydrogen peroxide producing compound to increase the potency and effectiveness of the oxidizer.
