  • Patent number: 7879787
    Abstract: An oxidizing cleaning composition comprises a low concentration of aqueous hydrogen peroxide that is environmentally friendly and has good stability in strong alkaline solutions. The aqueous hydrogen peroxide composition contains a synergistic combination of one or more hydrophilic surfactants having an HLB of 10 or greater, one or more hydrotropes, one or more UV-analyzable surfactants having an aromatic detectable functional group, and optionally a surfactant having an HLB of less than 10. The cleaning composition when mixed with an alkaline compound is very effective in removing dried or baked residues of polymers, modified or natural celluloses starches, natural gels, and the like at low concentrations and temperatures.
    Type: Grant
    Filed: May 27, 2010
    Date of Patent: February 1, 2011
    Assignee: American Sterilizer Company

  • Patent number: 7648583
    Abstract: An aqueous, concentrated neutral detergent composition for use in cleaning medical instruments and metal components (parts, tools, utensils, vessels, equipment, and surfaces) having scale control and corrosion inhibition properties when diluted to about 1/40 ounce per gallon to about 1/10 ounce per gallon in potable water. In addition, the concentrate may be applied directly to metal surfaces, such as stainless steel, to remove rust and other stains, without causing any additional corrosion or other damage to the metal surface.
