Zentek Ltd. (“Zentek” or the “Company”) (Nasdaq: ZTEK; TSX-V: ZEN), an intellectual property development and commercialization company, announces that SGS Standard Technical Services Co. (“SGS”) recently conducted tests to determine the extent of the antimicrobial properties and the time required to achieve deactivation of bacteria and virus on ZenGUARD™-coated mask material.
“Our goal at Zentek from early on in the pandemic was to create a technology that could improve the health and safety of our valued frontline healthcare workers” said Greg Fenton, CEO of Zentek. “Our patented ZenGUARD™ antimicrobial technology with 99.99% bacterial and viral filtration efficiency brings an added level of protection that doctors, nurses and all frontline healthcare providers deserve. We are excited to bring our unique ZenGUARD™ surgical masks to them via our Canadian distribution partnership with Southmedic Inc.”
Key Data points
Antibacterial testing completed by SGS following AATCC 100-2019 Test
Method for Antibacterial Finishes on Textile Material
Antiviral testing completed by SGS and followed ISO 18184: 2019 Textiles – Determination of antiviral activity of textile products TCID50 method
The ZenGUARD™-coated mask fabric demonstrated over 99.99% antibacterial effectiveness after 1 hour where 260,000 Escherichia Coli (E. coli) Colony Forming Units (CFU) was reduced to under 100 CFU.
The untreated control mask samples saw 120,000 E. coli CFU grow to 2.5 million in 1 hour and 1.1 billion in 8 hours
The ZenGUARD™-coated mask fabric demonstrated 86.7% antiviral effectiveness after 1 hour against H1N1 and 99.7% after 8 hours
These meaningful reductions in bacterial and viral load may have an impact in the reduction of infectious disease in high-risk environments
Impact in High-Risk Environments
In the context of high-risk indoor settings, such as hospitals where doctors, nurses and other healthcare professionals and patients wear surgical masks and are exposed to dangerous bacteria and viruses daily, this data offers compelling evidence that ZenGUARD™-coated mask material can provide additional protection with the strong antimicrobial properties of ZenGUARD™. The reduction in bacterial and viral growth in the mask materials may contribute to protecting doctors, nurses, other hospital staff and patients, as well as long term care residents and their caretakers, from mask acne to potentially preventing significant disease from bacterial or viral infections.
