Swiss speciality textile chemistry company HeiQ's antiviral textile technology, developed for use against the coronavirus, has been certified as safe and sustainable as all its ingredients are cosmetic grade, bio-based and recycled.

HeiQ Viroblock NPJ03 was proven to reduce 99.99% of human coronavirus SARS-CoV-2, the virus that causes Covid-19, along with other enveloped viruses and bacteria.

The textile treatment is for industrial use, designed to provide textiles with antiviral and antibacterial properties. The combination of silver antimicrobial technology and vesicle technology act to "rapidly destroy" enveloped viruses including coronaviruses. It has previously been tested against coronavirus 229E, another strain of virus in the coronavirus family.

"Since HeiQ Viroblock NPJ03 was designed for use on face masks to impart enhanced protection against viruses and bacteria, we selected only the most effective, safest and most sustainable ingredients," says Carlo Centonze, co-founder and CEO of HeiQ Group. "Furthermore, we are proud that HeiQ Viroblock NPJ03 qualifies as a bio-based renewable product and is 100% made from INCI approved cosmetic ingredients."

The HeiQ Viroblock NPJ03 is a formulation that contains a minute amount of recycled silver active ingredient and fatty liposome vesicle components. It is EU REACH and US FIFRA compliant, OekoTex certified, ZDHC and Bluesign homologised. Treated textile articles are compliant with EU BPR and US EPA. HeiQ Viroblock respirator masks with antibacterial and antiviral surface have been registered as medical device by Swissmedic and approved by US FDA.

Beta Analytics Testing Laboratory certified that HeiQ Viroblock NPJ03 contains 72% bio-based carbon. Test results are accredited to ISO/IEC 17025:2005 Testing Accreditation PJLA #59423 standards. HeiQ Viroblock NPJO3 is currently undergoing homologation for the USDA bio-preferred certification.

Specialities SRL (Italy), a surface chemistry research and development company, has also confirmed that all ingredients of HeiQ Viroblock NPJ03 are selected from the International Nomenclature of Cosmetic Ingredients (INCI).
