[0004] It is an object of the present invention to provide an aqueous solution that is safe and can sustain high sterilizing power for a long time.

[0005]

Means for Solving the Problems To achieve the above object, the sterilizing aqueous solution of the present invention dissolves and extracts metamorphic rock mainly composed of chlorite with inorganic acid, and then dilutes this extract with water. In addition, it is characterized by containing, as an active ingredient, a salt and / or a double salt of a plurality of metals and nonmetals and an inorganic acid obtained by further removing insolubles as the case may be.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The metamorphic rock used in the present invention is mainly composed of chlorite, a clay mineral obtained by metamorphism of a mica-based mineral (biotite). Depends on

The inorganic acid is preferably sulfuric acid, hydrochloric acid, nitric acid, or a mixture of any two or three of these, from the viewpoint of the ease of dissolving and extracting metamorphic rocks.
A sulfuric acid aqueous solution having a concentration of 0 to 20% by weight is preferred.

In the present invention, the salts and / or double salts extracted from the metamorphic rocks with inorganic acids include, specifically, sodium hydrogen sulfate, sodium sulfate, potassium hydrogen sulfate, potassium sulfate, ferrous sulfate, and sulfate sulfate. Ferric iron, aluminum sulfate, and the like, and alum, sodium aluminate, iron alum, and the like can be mentioned. Therefore, as a plurality of metals and nonmetals contained in the sterilizing aqueous solution of the present invention, high sterilizing power and its sustainability In terms of sex, iron, calcium, sodium, potassium, magnesium, copper,
Preferred are zinc, manganese, cobalt, germanium, vanadium, silicon, aluminum, lithium, rubidium, strontium, phosphorus, fluorine, and / or sulfur.

As the water for diluting the extract with the inorganic acid from the metamorphic rock, tap water, ion-exchanged water and the like can be used depending on the purpose. In particular, ion-exchanged water is used for sterilization of foods and tableware. preferable. The dilution ratio of the extract with water may be any ratio depending on the purpose. However, for washing and sterilizing dishes, cooking utensils, etc., the total of the total ion concentration is 10,000.
It is preferable to dilute at a dilution factor of 2 to 100 times, particularly at a dilution ratio of 5 to 10 times, so as to be about 0 ppm.
