摘要:
Disclosed are a two-agent type disinfectant composition for hard articles, which includes a first agent containing a powder mixture (A) and a second agent containing an aqueous hydrogen peroxide solution (B-1), the powder mixture (A) containing an alkali metal salt (A-1) exhibiting basicity when the salt is in the form of an aqueous solution, a water-soluble copper salt (A-2), a compound (A-3) represented by the following formula (1), and a nonionic surfactant (A-4) represented by the following formula (2), and in which the molar ratio of the water-soluble copper salt (A-2) and the compound (A-3) represented by the mixing amount of (A-3)/mixing amount of (A-2) is 3.0 to 20; and a single-agent type disinfectant composition for hard articles, which includes the components (A-1) to (A-4), and an inorganic peroxide (B-2) that releases hydrogen peroxide in water, and in which the molar ratio of the water-soluble copper salt (A-2) and the compound (A-3) represented by the mixing amount of (A-3)/mixing amount of (A-2) is 3.0 to 20. Disinfectant compositions for hard articles which have high disinfecting power against the surfaces of hard articles, have satisfactory stability of hydrogen peroxide in water, and have low foaming tendency, and a method for disinfecting the surface of a hard article by using the disinfectant composition for hard articles, can be provided.
摘要:
The present invention provides a sterilization auxiliary for ozone sterilization which is an aqueous solution including a Component (A) of an aluminum compound which produces aluminum ions in an aqueous solution, and a Component (B) of one or more of acids selected from phosphoric acid, citric acid, malic acid, succinic acid, gluconic acid, lactic acid, and L-tartaric acid, wherein the pH of the aqueous solution is greater than or equal to 1.0 and less than 5.0, and an ozone sterilization method for ozone-treating a substance to be treated using the sterilization auxiliary. According to the present invention, a sterilization auxiliary for ozone sterilization in which a high sterilizing effect may be obtained using less ozone without burdening sterilization apparatus and a substance to be treated, and a low-cost ozone sterilization method using the sterilization auxiliary can be provided.
