[Figure 3] 1 is Table 3 showing test results of the disinfecting coating compound according to the example of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0019] The disinfecting coating compound according to the present invention will be described below by way of examples with reference to the drawings. [Example]

[0020] The disinfecting coating compound according to this example contains copper, zinc, silver, essential oils, and distilled water. When used, this is used as an undiluted solution, which is diluted 30 to 120 times with distilled water and sprayed.

[0021] Table 1 shown in FIG. 1 is a list of ingredients of the disinfecting coating compound according to this example, and shows a total of 10 types, No. 0 to No. 9.

[0022] The disinfecting coating compound according to this example is a mixture of a copper sulfate aqueous solution containing copper, a zinc solution containing zinc, a silver ion solution containing silver, and water (distilled water). The copper sulfate aqueous solution has a concentration of 1 mol / L. The zinc solution has a concentration of 0.1 mol / L. The silver ion solution has a concentration of 1500 ppm.

[0023] As for the essential oils, it is a mixture of oregano oil (referring to essential oil extracted from oregano; the same applies below), cardamom oil, cinnamon katza oil, peppermint oil, eucalyptus globulus oil, litsea oil, lemongrass oil, tea tree oil, and benzoin oil.

[0024] Table 2 in Figure 2 is a composition table of essential oils. All blend ratios are in mass %. As shown in Figure 2, the optimal blend ratios of each oil are 10 mass % oregano oil, 10.0 mass % cardamom oil, 10.0 mass % cinnamon katza oil, 12.5 mass % peppermint oil, 10.0 mass % eucalyptus globulus oil, 17.5 mass % litsea oil, 10.0 mass % lemongrass oil, 12.5 mass % tea tree oil, and 7.5 mass % benzoin oil.

[0025] The essential oil may be emulsified with a surfactant and then mixed with an aqueous copper sulfate solution, a zinc solution, and a silver ion solution.

[0026] The antibacterial coating compound according to this example was diluted 30 times and the diluted solution was soaked in the diluted solution, and a test was conducted in accordance with the JIS standard (JIS L 1902:2015 Antibacterial test method and antibacterial effect for textile products) to investigate the antibacterial effect (however, the JIS standard requires that the antibacterial effect be confirmed after 18 to 24 hours, but in this case the antibacterial effect was confirmed after 15 seconds).

[0027] As a result of the above test, a 30-fold diluted solution of the disinfecting coating compound of this example was found to have a bactericidal effect against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. Furthermore, when a similar test was performed on a 120-fold diluted solution, the bactericidal effect was also found.

[0028] This point will be explained in detail using Figure 1 and Table 3 shown in Figure 3. Table 3 shows the results of the above test. Points where a bactericidal effect was observed as a result of the test are marked with a circle.

[0029] As shown in Table 1, No. 0, the disinfecting coating compound of this example was 2.5 ml of copper, 5.0 ml of zinc, 0.5 ml of silver, 0.2 ml of essential oil, and 1.8 ml of distilled water, i.e., 25.0 vol% copper, 50.0 vol% zinc, 5.0 vol% silver, 2.0 vol% essential oil, and 18.0 vol% distilled water (note that copper, zinc, and silver here refer to the above-mentioned copper sulfate aqueous solution, zinc solution, and silver ion solution, respectively. This also applies hereinafter.) When the above-mentioned test was performed on the diluted solution obtained by diluting this 30-fold or 120-fold, it was found to have a bactericidal effect against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, as shown in Table 3.

[0030] In addition, as in No. 1, the disinfecting coating compound of this example was 125.0 ml of copper, 500.0 ml of zinc, 50.0 ml of silver, 20.0 ml of essential oil, and 305.0 ml of distilled water, i.e., 12.5 vol% copper, 50.0 vol% zinc, 5.0 vol% silver, 2.0 vol% essential oil, and 30.5 vol% distilled water. When the above test was performed on diluted solutions obtained by diluting this 30-fold or 120-fold, it was found to have a bactericidal effect against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, as shown in Table 3.

[0031] In addition, as in No. 2, the disinfecting coating compound of this example was prepared by mixing 0.0 ml of copper, 500.0 ml of zinc, 50.0 ml of silver, 20.0 ml of essential oil, and 430.0 ml of distilled water, i.e., 50.0 vol% zinc, 5.0 vol% silver, 2.0 vol% essential oil, and 43.0 vol% distilled water. The above-mentioned test was carried out on the diluted solution obtained by diluting this 30-fold or 120-fold, and it was confirmed that it had a bactericidal effect against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, as shown in Table 3.

[0032] In addition, as in No. 3, the disinfecting coating compound of this example was 250.0 ml copper, 250.0 ml zinc, 50.0 ml silver, 20.0 ml essential oil, and 430.0 ml distilled water, i.e., 25.0 vol% copper, 25.0 vol% zinc, 5.0 vol% silver, 2.0 vol% essential oil, and 43.0 vol% distilled water. The above-mentioned test was performed on the diluted solution obtained by diluting this 30-fold or 120-fold, and it was confirmed that it had a bactericidal effect against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, as shown in Table 3.

[0033] Also, as in No. 4, the disinfecting coating compound of this example was 250.0 ml copper, 0.0 ml zinc, 50.0 ml silver, 20.0 ml essential oil, and 680.0 ml distilled water, i.e., 25.0 vol% copper, 5.0 vol% silver, 2.0 vol% essential oil, and 68.0 vol% distilled water. This was diluted 30-fold or 120-fold, and the above-mentioned test was performed. As shown in Table 3, it was found to have a bactericidal effect against Staphylococcus aureus and Escherichia coli. On the other hand, no bactericidal effect was found against Pseudomonas aeruginosa.

[0034] In addition, as in No. 5, the disinfecting coating compound of this example was 250.0 ml copper, 500.0 ml zinc, 25.0 ml silver, 20.0 ml essential oil, and 205.0 ml distilled water, i.e., 25.0 vol% copper, 50.0 vol% zinc, 2.5 vol% silver, 2.0 vol% essential oil, and 20.5 vol% distilled water. This was diluted 30 times or 120 times and the above test was performed. As shown in Table 3, it was confirmed that it had a bactericidal effect against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa.

[0035] Also, as in No. 6, the disinfecting coating compound of this example was prepared by mixing 250.0 ml of copper, 500.0 ml of zinc, 0.0 ml of silver, 20.0 ml of essential oil, and 230.0 ml of distilled water, i.e., 25.0 vol% copper, 50.0 vol% zinc, 2.0 vol% essential oil, and 23.0 vol% distilled water. The above-mentioned test was carried out on a diluted solution obtained by diluting this 30-fold or 120-fold, and it was found to have a bactericidal effect against Staphylococcus aureus and Pseudomonas aeruginosa, as shown in Table 3. However, no bactericidal effect was observed against Escherichia coli.

[0036] In addition, as in No. 7, the disinfecting coating compound of this example was diluted 30 times or 120 times with 250.0 ml of copper, 500.0 ml of zinc, 50.0 ml of silver, 10.0 ml of essential oil, and 190.0 ml of distilled water, i.e., 25.0 volume % copper, 50.0 volume % zinc, 5.0 volume % silver, 1.0 volume % essential oil, and 19.0 volume % distilled water, and the above test was performed on the diluted solution.As shown in Table 3, it was found to have a bactericidal effect against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa.

[0037] Furthermore, as in No. 8, the disinfecting coating compound of this example was mixed with 250.0 ml of copper, 500.0 ml of zinc, 50.0 ml of silver, 0.0 ml of essential oil, and 200.0 ml of distilled water, i.e., 25.0 mass% copper, 50.0 mass% zinc, 5.0 mass% silver, and 200% distilled water, and diluted 30 times or 120 times. It was confirmed that the diluted solution had a bactericidal effect against Escherichia coli and Pseudomonas aeruginosa, respectively. On the other hand, no bactericidal effect was observed against Staphylococcus aureus.

[0038] No. 9 was the same as No. 0, but six months had passed since mixing. The diluted solutions, diluted 30-fold or 120-fold, were found to have bactericidal effects against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, respectively.

[0039] From the above results, it was found that copper (copper sulfate aqueous solution) has a bactericidal effect even if it is not included in the disinfecting coating compound of this example, but that the bactericidal effect of zinc (zinc solution), silver (silver ion liquid), and essential oil is reduced if even one of these is missing.

[0040] Furthermore, it was found that a zinc solution with a concentration of 5.0% by volume or more and 50.0% by volume or less exhibits a bactericidal effect.

[0041] Furthermore, it was found that a silver ion solution with a concentration of 2.5% by volume or more and 50.0% by volume or less exhibits a bactericidal effect.

[0042] Furthermore, it was found that essential oils exert a bactericidal effect when the concentration is between 2.5% and 50.0% by volume.

[0043] Furthermore, the effectiveness of diluted solutions prepared by soaking fabrics in a solution diluted 30 times or 120 times with the disinfecting coating compound of this example against the novel coronavirus (COVID-19) was tested in accordance with JIS standards (JIS L 1902:2015 Antibacterial test methods and antibacterial effects for textile products). The results showed that the diluted solutions had a virucidal effect, i.e., an effect of inactivating the virus, against the novel coronavirus (COVID-19).

[0044] Therefore, the disinfectant coating compound of this example can be used to sterilize and kill viruses by spraying a diluted solution on toilets, handrails, doorknobs, walls, etc. Therefore, the disinfectant coating compound of this example can reduce the risk of infection with viruses, etc.

[0045] Furthermore, the antibacterial coating compound according to the present invention does not contain titanium oxide, unlike the conventional antibacterial coating agent disclosed in Patent Document 1, and contains only naturally derived components, and therefore has less adverse effects on the human body. [Industrial Applicability]

[0046] The present invention is suitable as a disinfectant coating compound.
