[0287] In the present embodiment, a test is carried out to detect the persistence of the bactericidal effect of the chlorous acid aqueous solution stored at 40° C. for 40 days (converted to 240 days at normal temperature) used in Example 2 to the bactericidal effect of the test bacteria, Here, the chlorous acid aqueous solution stored at 40° C. for 40 days used in Example 2 was diluted arbitrarily and further stored at normal temperature for 30 days. Even when the aqueous solution of chlorous acid was stored under harsh conditions such as at 40°C and diluted to a specified concentration, and then the diluted solution was stored at room temperature for 30 days, no bactericidal effect on Escherichia coli or Staphylococcus aureus was observed Loss or reduction of effectiveness. Its stabilizing effect was confirmed.

Abstract

The present invention provides a technique enabling long-term preservation of a chlorous acid aqueous solution and novel application thereof. A sterilizing agent comprising an aqueous solution comprising chlorous acid (chlorous acid aqueous solution), which is used as a sterilizing agent, comprises a chlorous acid aqueous solution, metal hydroxide, and metal phosphate. Preferably, an agent in which potassium is the metal and / or pH is 3.5 or higher and less than 7.0 is prepared, whereby an unexpected long-term stabilizing effect was demonstrated. Further, the present invention provides: a sterilizing agent for preventing secondary contamination, comprising a chlorous acid aqueous solution, or an article impregnated with a chlorous acid aqueous solution for preventing secondary contamination; an article impregnated with a chlorous acid aqueous solution for sterilizing a floor surface; an agent for removing odor comprising a chlorous acid aqueous solution or an article impregnated with a chlorous acid aqueous solution for removing odor; and an agent for removing microbes adhering to the body, comprising a chlorous acid aqueous solution or an article impregnated with a chlorous acid aqueous solution for removing body adhering microbes.

Description

technical field [0001] The present invention relates to a long-term storage chlorous acid aqueous solution and a long-term storage disinfectant using the chlorous acid aqueous solution. Further, the present invention relates to a new application of an aqueous solution of chlorous acid. Background technique [0002] Chlorous acid aqueous solution has attracted much attention as a food additive. However, there is a problem that an aqueous solution of chlorous acid is difficult to produce, and even if it can be produced, it cannot be preserved under normal conditions. [0003] The present inventors have discovered an aqueous solution of chlorous acid and a production method thereof. The bactericidal effect on Escherichia coli has been verified, and thus a patent application has been filed thereon (Patent Document 1).
