I read there are different strengths required for isopropyl alcohol and Ethanol to destroy this particular virus, also I think the minimum recommended strength has been increased very slightly after further testing. I think slightly lower strengths can work but they would need to stay on the hands longer than would be considered practical. There's a general article on chemical disinfectants here (not all are safe to use on skin) :- https://www.cdc.gov/infectioncontrol/guidelines/disinfection/disinfection-methods/chemical.html
(confused) I keep reading 60% alcohol is effective, but TJC say in their presentations that it's 70%
The product page does say this kills flu, it also says "the active ingredients have been tested positively for killing SARS" However, while SARS is a type of coronavirus, it doesn't say that this product will kill SARS, or even if it contains the active ingredients in sufficient strength to be expected to "kill" SARS. So it might be effective, or might not. http://mcklords.com/2020/02/26/sursol-instant-hand-sanitiser/
Really? Essentially, all viruses contain the following two components: 1) a nucleic acid genome and 2) a protein capsid that covers the genome. Together this is called the nucleocapsid. In addition, many animal viruses contain a 3) lipid envelope. The entire intact virus is called the virion. Based on this information and the fact that products utilising electrolysed water are proven weapons against viruses, I have no reason to believe that it will not be effective, as a disinfectant, against the Coronavirus.
