Morning all

Can anybody help / advise

I am doing a COSHH RA for a substance 'V-San sanitiser', unclassified under chp and apparently harmless. This solution is the only solution used in a portable 'Fogging' machine that is used to disinfect vehicle cabs after suspected covid 19 contamination.

In doing the COSHH RA I asked the supplier about the effectiveness of the fogging process against coronavirus. They sent me a product specification document that contained another MSDS for a chemical called Bardac 22. The supplier advised that it is the Bardac 22 that effectively disinfects coronavirus

This raised further questions that I hope you can help me with;

Basically the suppliers are telling me that the substance Bardac 22 is part of the solution 'V-San' but that because the quantity of Bardac 22 is small there is no requirement to note its presence in the V San MSDS.

My questions are;

1. The substance Bardac 22 is classified as a corrosive and as being dangerous to the environment. Is it right that this product can be part of the solution V-San without it being detailed on the V San MSDS?

2. Is there a standard quantity (percentage) of a solution at which there is no need to detail on an MSDS?

3. If I do not know the quantity of Bardac 22 contained in the V San mixture how can I know if it is effective against coronavirus?

Thanks in advance for any help

Is this an actual SDS? https://oversiz.ru/f/bardac22piseng0203.pdf

Bardac22 is described as effective against enveloped virus and Covid 19 is an enveloped virus but strictly speaking they are ASSUMING that it is effective against Covid 19. For example the Defra approved list of disinfectants for use  in farming actually have to be tested against the specific pathogen- http://disinfectants.defra.gov.uk/DisinfectantsExternal/Default.aspx?Module=ApprovalsList_SI

Snice Covid 19 is new disease it might be acceptable to have evidence that it is effective against another coronavirus (there are at least dozen to choose from most of which are harmless to humans) but there is no evidence of that either.

Then there is of course the fact what you are buying is not Bardac22 but STURDY VSAN Sanitising Machine. There is as far as I can see only on UK supplier. The blurb seems to emphasise that is gets rid of odours as much as pathogens. I have no idea where it comes from and what its effectiveness actually is. The ad implies that it “our V-SAN's special agents attack and destroy all germs, bacteria, viruses and spores in its path. Replacing them with a long lasting freshness and leaving you with a much cleaner, safer environment.” Which sounds too good to be true. I’d expect data saying how effective is at what concentrations, in what conditions: Fogging systems re very temperature and humidity dependent.

You still need an SDS telling you what this V-SAN Vehicle Sanitising Solution actually is. If it is “harmless” , it would be the first disinfectant that I have ever come across that is totally harmless.

AK - that is a product data sheet from the US manufacturer Lonza.

John - MSDS/chp are expired terms (June 2017). An SDS classified according to CLP has lower declaration thresholds for substances particularly active substances covered by the Biocidal Products Regulations due to the possibility of reaction at trace amounts. Under the old CHiP regulations many ignored substances less than 0.1%

Whilst the active substance named may appear on the BPR list supply and use within the EU should be for approved active substances sourced from EU based suppliers. The US has different regulations on chemical substances despite using (a version of) the Globally Harmonised System.

Plus, at the same time our V-SAN's special agents attack and destroy all germs, bacteria, viruses and spores in its path.

Someone is making false claims to market and I suspect may be totallly ignorant of the supply chain regulations.

Ask them for the results of their testing e.g. BS EN 13697 for Covid
