  • Patent number: 8163101
    Abstract: A method for cleaning contaminated surfaces of surgical waste management equipment. The method includes rinsing surfaces of the equipment with water to remove water soluble contaminants and waste material. A rinse solution is applied to the surfaces of the equipment to provide a residual film thereon. The rinse solution includes a first nonionic alkoxylated alcohol surfactant having an HLB value ranging from about 12 to about 15, a second nonionic alkoxylated alcohol surfactant having an HLB value ranging from about 16 to 20, an aqueous solvent, and a bio-film permeation agent. A total of the first surfactant and the second surfactant in the composition ranges from about 2 to about 20 percent by weight of a total weight of the composition.
    Type: Grant

  • Patent number: 7893015
    Abstract: An alkaline composition is described having a first nonionic alkoxylated alcohol surfactant having an HLB value ranging from about 10 to about 15, a second nonionic alkoxylated alcohol surfactant having an HLB value ranging from about 16 to 20, an aqueous solvent, and a bio-film permeation agent. A total amount of the first surfactant and the second surfactant in the composition ranges from about 2 to about 20 percent by weight of a total weight of the composition.

  • Publication number: 20090203565
    Abstract: A composition is described having a first nonionic alkoxylated alcohol surfactant having an HLB value ranging from about 10 to about 15, a second nonionic alkoxylated alcohol surfactant having an HLB value ranging from about 16 to 20, an aqueous solvent, and optionally, a bio-film permeation agent. A total of the first surfactant and the second surfactant in the composition ranges from about 2 to about 20 percent by weight of a total weight of the composition, and a ratio of the second surfactant to the first surfactant in the composition ranges from about 2:1 to about 4:1. A method for treating contaminated surfaces of surgical waste management equipment is also described. The method includes rinsing surfaces of the equipment with water to remove water soluble contaminants and waste material. A rinse solution is applied to the surfaces of the equipment to provide a residual film thereon.

  • Patent number: 7198680
    Abstract: A method for cleaning contaminated surfaces of surgical waste management equipment. The method includes rinsing surfaces of the equipment with water to remove water soluble contaminants and waste material. A rinse solution is applied to the surfaces of the equipment to provide a residual film thereon. The rinse solution includes a first nonionic nonylphenol surfactant having an HLB value ranging from about 10 to about 15, a second nonionic nonylphenol surfactant having an HLB value ranging from about 16 to 20, a bio-film permeation agent, and an aqueous solvent. A total of the first surfactant and the second surfactant in the solution ranges from about 2 to about 20 percent by weight of a total weight of the solution and a ratio of the second surfactant to the first surfactant in the solution ranges from about 2:1 to about 4:1.
