Panasonic Ecology Systems Co., Ltd. (PES) has recently verified that hypochlorous acid water (approx. 10 mg/L) at a pH of 8.5, inhibits more than 99.99% of the Novel Coronavirus (SARS-CoV-2) in one minute in collaboration with the global contract research organization Texcell(*2).
The hypochlorous acid water has a powerful effect on sterilization and deodorization. PES has developed hypochlorous acid technology for over 30 years since it employed hypochlorous acid water as part of the system to maintain the optimal sanitary conditions of beverage vending machines with an automatic cup dispenser in 1987(*3).
In a joint effort with a public research institute, PES has demonstrated that hypochlorous acid water has an inhibitory effect on the novel influenza virus, MRSA (methicillin-resistant Staphylococcus aureus), rotavirus, etc. In a recent test conducted with Texcell, the company verified that hypochlorous acid water (approx. 10 mg/L) at a pH of 8.5 inhibits more than 99.99% of the Novel Coronavirus (SARS-CoV-2) in one minute. This verification is a basic study and does not evaluate the performance of products equipped with hypochlorous acid water.
PES will continue to improve hypochlorous acid technology in an effort to contribute to clean and comfortable indoor air quality.
The Novel Coronavirus (SARS-CoV-2) was subjected to a test, in which the virus fluid was placed in contact with hypochlorous acid water at a pH of 8.5. In the test, the virus fluid and hypochlorous acid water were mixed at a ratio of 1:99.
More than 99.99% of the Novel Coronavirus (SARS-CoV-2) was inhibited in one minute.
. Testing agency: Texcell
. Target: Novel Coronavirus (SARS-CoV-2)
. Results: The inhibition of more than 99.99% of the virus in one minute was verified.
| time | Inhibition rate |
