| abstract |
The present invention is a peracetic acid-based sterilizing composition liquid containing peracetic acid, acetic acid, hydrogen peroxide, and catalase enzyme, wherein the sterilizing liquid has a pH in the range of 2.6 to 5.0, and the catalase enzyme is It is contained in an amount of 0.1 to 10 μg / ml, the concentration of the peracetic acid is 500 to 10,000 ppm, and the concentration of the hydrogen peroxide is less than 500 ppm, so that it is efficiently peroxidized by a small amount of catalase enzyme. Hydrogen can be reduced, and foaming resulting from the catalase enzyme formulation can be suppressed. |
