ADDMASTER has received many questions from customers and end-users about the efficacy of Biomaster antimicrobial technology against viruses in general and its potential use against the spread of Covid-19.
Covid-19 is an enveloped virus and relies on a protective lipid coating. These are the easiest types of virus to deactivate. Unlike many gastrointestinal viruses such as Norovirus which have a tough protein shell called a capsid enveloped virus, viruses with this lipid coating are relatively vulnerable and easier to destroy.
There are several methods available to destroy the lipid coating:
- Alcohol-based products disintegrate the protective lipids.
- Quaternary ammonium disinfectants, commonly used in healthcare and food-service industries, attack protein and lipid structures, thwarting the pathogen’s typical mode of infection.
- Bleach and other potent oxidizers will also break down the essential components of a virus.
These methods are highly effective at removing dangerous pathogens from surfaces, but they only remain effective for up to two hours maximum. Any new microbes landing on the surface after that will continue to thrive.
Biomaster and viruses
Biomaster antimicrobial technology is primarily effective against bacteria but is also highly effective against the growth and proliferation of viruses on porous surfaces such as textiles and paper. When microbes land on an untreated fabric or surface they multiply. When they land on the surface of a Biomaster protected fabric or paper, the silver ions trapped in the surface prevent microbial growth. Biomaster antimicrobial technology has been proven effective at reducing the viability of Norovirus on porous surfaces including treated fabrics and papers.
In independent laboratory tests* analysis identified that Biomaster fabric spray is effective at reducing the viability of Norovirus applied to textiles. The effects of the spray on the virus were measured after five minutes, 30 minutes and one hour. The outcome was a virucidal effect on the test virus by 93 per cent in half an hour, and 99 per cent within an hour.
The evidence proves the efficacy of Biomaster fabric spray in the reduction of microbial load in fabrics, both bacterial and viral, reducing risk to all types of fabrics.
