Low odor, hard surface sporicides and chemical decontaminants

摘要

A low odor, liquid disinfectant composition comprising multiple components, which, upon mixing, provide an aqueous solution comprising low levels of peracetic acid for use in decontaminating articles and surfaces contaminated with bacteria, viruses, fungi and other chemical and biological contaminants including, but not limited to, spores, such as Clostridium difficile (C. diff), Clostridium sporogenes, and anthrax, mouse parvo virus, and mustard, nerve and other chemical and biological warfare agents. The disinfectant composition is prepared just prior to use by combining two or more separately packaged components, one component which is an acetyl donor comprising TAED or DAMA, and the other component which is a hydrogen peroxide solution.

主权项

1. A ready-to-use, multi-part composition that, upon combining the parts, generates, in situ, a low odor, neutral aqueous peracetic acid solution for use in decontaminating or disinfecting biological or chemical warfare agents, including spores, on hard surfaces, consisting essentially of:
a. as a first part, an acetyl donor consisting of liquid diacetylmethylamine (DAMA); b. as a second part, a hydrogen peroxide solution, wherein the concentration of hydrogen peroxide is present in amounts less than about 10 weight percent; c. an alkalinity source included as a third part or combined with the first part, wherein the alkalinity source is selected from the group consisting of an anhydrous ammonia, ammonium hydroxide, triethylamine, triethanolamine, ethanolamine, diethanolamine, 2-(methylamino) ethanol, R-(−)-2-amino-1-butanol, 2(tert-butylamino) ethanol, or 2-(2-amino ethylamino) ethanol, and mixtures thereof; d. optionally, a low-foaming surfactant included in the first part; and e. water; wherein the composition is without the presence of detersive surfactants, enzymes, builders, foaming agents, anti-gel additives, or viscosity control agents, wherein the liquid acetyl donor, hydrogen peroxide solution and alkalinity source are mixed together just prior to use to form the peracetic acid solution, and wherein the peracetic acid solution requires no or less rinsing than other conventional decontamination or disinfecting compositions.
