Covid-19 is an illness caused by SARS-CoV-2, which is a Coronavirus. Coronaviruses have been around for a long time and belong to a group known as ‘enveloped viruses’. Below is some science behind how QAT based products such as the one we use to combat enveloped viruses.
This is a basic ‘enveloped’ virus. The virus is enclosed by a lipid membrane (a fat like substance). This membrane (envelope) is used by the virus to attach itself to the host cell, the virus then penetrates the host cell and replicates itself. The envelope is actually quite fragile, and susceptible to changes in temperature, pH levels and disinfectants.
Examples of Enveloped Viruses are Chicken Pox, Influenza A, Hepatitis C, HIV and of course, Coronaviruses.
Like most enveloped viruses, outside of the human body they are very weak and easily destroyed with hot water and disinfectant (hence all the media advice to wash your hands) Needless to say, you cannot kill viruses so easily once they are inside the human body.
There are various agents that are effective against enveloped viruses, the best one is actually common bleach, but you can’t go splashing that stuff around customers’ soft furnishings! The most well known version is probably alcohol, such as in some hand sanitisers, it works very quickly but it evaporates just as quickly and so has no residual effect.
QATs (or quaternary ammonium compounds), the active ingredient in our sanitiser, take longer to work but provide longer lasting protection. They are best applied and left on the surface in order to (in effect) kill the virus. They work by disrupting the envelope membrane, which exposes the nucleocapsid, affecting it‘s ability to infect subsequent cells.
The great thing about QAT’s is that you can use them on wet cleanable carpets, rugs, leather and fabric upholstery fabrics.
The active ingredients in the Virus & Bacteria Cleaners & Sanitisers we use has been tested and proven to be effective against most known microbes, including bacteria, viruses, fungi and mould. It is tested and proven to be effective against the following standards:
• EN14476 – European Standard against viruses
• EN1276 – European Standard against bacteria
• EN1650 – European Standard against fungi
In addition it:
• Leaves a lasting layer of protection (subject to environmental factors)
• Water based
• Safe for use with children, elderly & pets
• Bio degradable
Crucially, this product has been tested and is effective against all enveloped viruses as defined in EN 14476:2013 + A2:2019 Annex
A*. This therefore includes all coronaviruses and SARS‐CoV‐2 which causes the illness Covid-19.
