  • Patent number: 8778370
    Abstract: A composition and method for treating industrial water is described, wherein the composition has microbe inhibiting properties. The composition utilizes a cationic phase transfer agent, such as a quaternary ammonium compound in the presence of a peroxide source. The composition does not significantly reduce the anti-scaling properties of anionic dispersants present in the water.

  • Publication number: 20120111743
    Abstract: A binary composition is provided comprising two liquids, which are separately maintained prior to forming an admixture during delivery to a hard surface, vessel, or drain. The admixture generates foam of sufficient stability and quantity to effect disinfection and biofilm removal. A first liquid preferably includes a quaternary ammonium compound, a peroxygen agent and, optionally, surfactants, thickening and chelating agents (colorants, corrosion inhibitors, stabilizers, perfume, etc). The second liquid preferably includes a hypohalite generating agent, a source of alkalinity, and optionally, a surfactant and thickening and chelating agents (colorants, corrosion inhibitors, stabilizers, perfume, etc.). Because the two liquids are initially separated, the hy-pohalit and peroxygen agent can be maintained in an environment that is favorable to their stability until the time of use. When the two liquids are mixed, the hypohalite and peroxygen react to liberate oxygen gas.

  • Patent number: 5620527
    Abstract: A cleansing and disinfecting composition comprising an alkaline per-salt and a positively charged phase-transfer agent. The composition preferably also contains a surfactant. The alkaline per-salt is an alkaline water-soluble salt having hydrogen peroxide of crystallization. The positively charged phase-transfer agent is preferably a quaternary ammonium salt. The composition may be formulated as a cream, a bulk powder, a solution or tablets. It may also be incorporated in wipes, sponges and brushes. The compositions of this invention find utility in health care, as disinfectants in surgical applications, and as decontaminating agents. Specific uses include skin cleansing and disinfecting, treatment for exposure to toxic plants such as poison ivy, treatment for exposure to industrial and agricultural chemicals such as herbicides and pesticides, and cleansing and disinfecting surfaces and sensitive equipment.

  • Patent number: 5320805
    Abstract: A method of using a chemical composition as a cleanser, sanitizer, disinfectant, sporicide, fungicide and sterilizer by applying an effective amount of the composition to objects and surfaces requiring the application of a cleanser, sanitizer, disinfectant, sporicide, fungicide or sterilizer, the composition including from about 10% to about 90% by weight of an alkaline water-soluble salt having hydrogen peroxide of crystallization and from about a fraction of a percent to about 30% by weight of a positively charged phase-transfer agent selected from the group consisting of a phosphonium salt, a sulfonium salt, and a quaternary ammonium salt, said composition forming both a water and lipid soluble phase-transfer ion-pair.
