    • 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. The rinse solution includes 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.
    • 描述了具有HLB值为约10至约15的第一非离子烷氧基化醇表面活性剂,HLB值为约16至20的第二非离子烷氧基化醇表面活性剂,水性溶剂和任选的生物 - 薄膜渗透剂。 组合物中总计第一表面活性剂和第二表面活性剂的含量为组合物总重量的约2至约20重量%,组合物中第二表面活性剂与第一表面活性剂的比例为约2: 1至约4:1。 还描述了一种用于处理外科废物管理设备的污染表面的方法。 该方法包括用水冲洗设备表面以除去水溶性污染物和废料。 将冲洗溶液施加到设备的表面以在其上提供残留的膜。 漂洗溶液包括HLB值为约10至约15的第一非离子烷氧基化醇表面活性剂,HLB值为约16至20的第二非离子烷氧基化醇表面活性剂,水溶剂和任选的生物膜 渗透剂。 组合物中总计第一表面活性剂和第二表面活性剂的含量为组合物总重量的约2至约20重量%,组合物中第二表面活性剂与第一表面活性剂的比例为约2: 1至约4:1。
