Tests confirm BI-OME effective against SARS-COV-2 after intense washing

BI-OME is said to be proven to achieve 99% and higher virus reduction, including of SARS-COV-2, on samples before washing and retains 98.5% even after 25 wash cycles

Belgian chemicals producer Devan has announced that new test results confirm the high-performance virus reducing capabilities of its BI-OME fabric coating technology on both unwashed and intensely washed fabrics. According to independent testing, Devan says,

BI-OME is proven to achieve 99% and higher virus reduction, including of SARS-COV-2, on samples before washing and retains 98.5% even after 25 wash cycles.

“In view of the COVID-19 pandemic and fast-approaching autumn/winter flu season, we were keen to provide textile manufacturers with concrete assurance regarding virus reduction performance on washed samples according to ISO 18184. This exceeds the limitations of the post-wash antimicrobial results most commonly shared for other technologies, giving the textile industry a clear, more precise overview of performance and wash durability,” comments Sven Ghyselinck, CEO of Devan.

Over recent months, Devan has worked closely with a series of international third-party laboratories to test different fabric substrates against a wide range of enveloped viruses. According to the company. before washing, samples treated with Devan BI-OME score very good to excellent (99% and higher according to ISO 18184) results on virus reduction.

Different substrates, like polyester, cotton and polycottons, were exposed to enveloped viruses like SARS-COV-2 (known to cause COVID-19), Feline Corona, Vaccinia (the EU standard for enveloped viruses) and Porcine Respiratory viruses. After 30minutes, BI- OME already reduced 99.96% of the activity of SARS-COV-2, Devan reports.

After washing, a decrease in virus reduction performance of coating technologies is normal and expected, Devan continues. However, BI- OME is confirmed to deliver only a minimal reduction, retaining up to 98.5% virus reduction even when the fabric is washed 25 times, it adds.

Devan says it is further improving its formulas to improve wash resistance even more and at the same time keep the economical add-on cost as low as possible. BI-OME is already endorsed by a wide range of companies and their collections span diverse applications including bedding, clothing, travel accessories, and transport.

According to Devan, BI-OME is a non-metal non-leaching quat silane-based chemistry, which is BPR (EU, TR) and EPA registered and Ökotex class 1 registered. Through its nature it is inherently biodegradable, concludes Devan.
