That quote was of the title, which itself was quoting a phrase. More complete quote, from the article:
Britain’s largest rail franchise is using disinfectant which it claims will kill coronavirus on surfaces for up to 30 days.
Keywords: "claims", and especially "up to"
Which leaves a lot of wiggle room in real-world applications. If it fails after 2 days for whatever reason, they've still met their claim.
In any case, the implication is that this is something fairly new. A health-care or food setting is going to have to wait for safety certifications before using it.
This claim "for up to 30 days", intrigued me. Intuitively, if it is going to do that it means it has to persist in the environment for 30 days and at an effective concentration.
The GTA quote has been carried by a number of news outlets and, as many have noticed, there is precious little about what the product is. I found one article that added, "...that sticks to surfaces..."
https://www.itv.com/news/anglia/2020-05-26/new-viruscide-being-used-by-govia-thameslink-to-kill-coronavirus-on-surfaces/ . OK, I am starting to get an idea of how this could work - imagine some chewing gum under the the table that had a whole lot of virucide in it that that does not evaporate readily - is it something like that?
Then I read this article
https://www.fox13news.com/news/cleaning-product-continues-killing-novel-coronavirus-30-days-after-application-company-claims - not about the GTA but a US Port (Tampa, Florida..cruise ships, that kind of thing)..... and they showed a bottle of the stuff and the name is in thee article, along with the 30-day claim...
mPale aha, getting closer.
So I go to the product site
http://www.mpactusa.com/ and I see this message:
Due to significant increased web traffic caused by the COVID-19 pandemic and residual web searches for our mPact™ Antimicrobial System, we have disabled our website temporarily. Please contact our headquarters for further inquiries regarding mPerial™ + mPale™ products.ok, ok, settle down, let's not assume quackery, if it is a commercial product in the US, we should be able to find it with (or without) certifications and with an associated MSDS.
AT this point, I don't know where the 30-day claim appears or what evidence is cited if it does appear.
Here is an MSDS for the product
http://www.cms-clean.com/wp-content/uploads/2011/11/mPale-MSDS-Sheets.pdfHere is a labeling revision for the EPA (from last year)
https://www3.epa.gov/pesticides/chem_search/ppls/083129-00001-20190312.pdfThe label does clearly tout durability but I still don't see a written 30-day claim. Note, however, that in the video, someone is identified, by name, as being from the company.
Adding the name to the search, I find another article
https://www.tampabay.com/news/business/2020/03/10/kill-coronavirus-with-microscopic-spikes-port-tampa-bay-says-yes/ where the mode of action is described:
When mPact’s antimicrobial treatment, known as mPale, is applied to a disinfected surface and is allowed to dry, the company says, it leaves a thin film of molecules that have a unique spiked structure and a positive electrical charge. Those microscopic spikes do two things, mPact says.
First, they bond with virtually any surface, though they are much too small to be seen or felt by human touch. Second, they attract bacteria, viruses, mold and fungi, which carry an opposite negative charge, into physical contact. On contact, the spikes punch through the cell walls of the microbes.
“It punctures the membrane," Evans said. "It does not allow it to attach to a host. It does not allow it to propagate. It’s thinking about disinfection in a different way.”
Then, I see it!“It’s absolutely safe,” Evans said. “It stays on for 30 days at the nano level. You can’t see it. You can’t feel it. It’s not something you can touch, but it continues to kill for 30 days. ... It’s a very effective disinfectant."...and also...
Three weeks ago, mPact sent its product to a German lab, which Evans said determined that it’s effective in eliminating 99.99 percent of the new coronavirus, known as COVID-19, which is short for “coronavirus disease 2019.”So, I guess some data does exists for the claim, but I am reserving comment until I can see those data (i.e., somebody who knows more than me evaluates those data).
The article also notes that the product is not on the EPA list of "Coronavirus" killers, to which the response was:
The company’s products are not on a U.S. Environmental Protection Agency list of antimicrobial products for use against the new coronavirus, but Evans said the company was on a call Monday with the U.S. Commerce Department, which he said was interested in getting the company in touch with a coronavirus task force that includes EPA officials.OK, that exceeds my interest in the matter and I apologize if I got something wrong.
