Quick answer: A disinfectant kills germs at the moment of application and then its effect ends. An antimicrobial coating like VireXbuster keeps working between those applications, forming a hybrid protective layer on a surface that continuously suppresses microbial growth for weeks or months. In the US, the EPA classifies this category as a Supplemental Residual Antimicrobial Product (SRAP) — supplemental to, not a replacement for, standard disinfection.
Who Makes VireXbuster?
DaXem GmbH, based in Eschborn, Hessen, Germany, develops and manufactures the VireXbuster product range: an antimicrobial coating (VireXbuster Spray), a waterborne antimicrobial wall paint for walls and ceilings (VireXbuster Wall), and an additive for polymer and plastics manufacturing, including polymer flooring (VireXbuster 4Bulk). All three are built on the same hybrid antimicrobial formulation — a technology with a very wide spectrum of activity against viruses, bacteria, fungi, mold and mildew.
Why Isn’t VireXbuster Called a “Disinfectant”?
Regulatory bodies reserve the term “disinfectant” for products that make an instant, one-time microbial kill claim, tested and registered under specific biocidal product frameworks. VireXbuster is deliberately positioned differently, because it does something different: it does not replace your existing cleaning and disinfection routine — it works between those routine disinfection events, when surfaces are otherwise unprotected. That is precisely the gap the EPA’s Supplemental Residual Antimicrobial Product (SRAP) category was created to describe.
What Does “Supplemental Residual Antimicrobial Product” Actually Mean?
Breaking down the EPA’s own terminology helps explain the category:
- Supplemental — used in addition to, not instead of, standard cleaning and disinfection protocols.
- Residual — the antimicrobial effect remains on the treated surface over an extended period, rather than evaporating or wiping away after one use.
- Antimicrobial — active against a broad spectrum of microorganisms, not a single pathogen.
This is why facility managers, hospitals and hospitality operators increasingly treat coatings like VireXbuster as a second, continuous layer of protection — sitting on top of, not replacing, the disinfectant they already use.
Is VireXbuster Independently Verified?
Yes. While VireXbuster is not EPA-registered as a disinfectant (by design, since it is not marketed as one), the underlying technology has been independently assessed by multiple bodies:
- BAuA approved — reviewed under the German Federal Institute for Occupational Safety and Health (Bundesanstalt für Arbeitsschutz und Arbeitsmedizin) biocidal product framework.
- Fraunhofer tested — efficacy testing conducted by the Fraunhofer Institute, one of Europe’s leading applied research organizations.
- QualityLabs certified — certified as antimicrobial by independent laboratory testing.
- Dermatest certified “Excellent” — rated dermatologically safe.
Together, these certifications give facility managers and specifiers a verifiable, third-party basis for the product’s antimicrobial and safety claims — without relying on marketing language alone.
Where Does an Antimicrobial Coating Fit in a Cleaning Program?
Think of surface hygiene as having two layers:
- Active disinfection — your existing scheduled cleaning and disinfecting routine, which delivers an immediate kill at the moment it’s performed.
- Residual protection — the hours or days between those cleaning events, when high-touch surfaces (door handles, handrails, light switches, HVAC components) are otherwise unprotected and re-contaminate quickly after every touch.
VireXbuster Spray, VireXbuster Wall and VireXbuster 4Bulk are built to cover that second layer, whether applied to existing surfaces, painted directly onto walls and ceilings, or manufactured directly into polymers, plastics and polymer flooring.
Which Sectors Use This Approach?
Healthcare facilities, public sector buildings, hospitality operators (including the VireXbuster Marine system used on cruise ships), and food and beverage environments are among the sectors layering residual antimicrobial protection onto their existing disinfection protocols, particularly on high-touch surfaces that are difficult to disinfect on a continuous basis.
Frequently Asked Questions
Is VireXbuster a disinfectant?
No. VireXbuster is an antimicrobial coating that provides supplemental, residual protection between disinfection events. It is designed to work alongside your existing disinfection routine, not replace it.
What is a Supplemental Residual Antimicrobial Product (SRAP)?
SRAP is a category the U.S. EPA uses to describe products that provide ongoing, residual antimicrobial protection on treated surfaces, in addition to (not instead of) standard disinfection practices.
Is VireXbuster EPA registered?
VireXbuster is not EPA-registered as a disinfectant, because it is not marketed or positioned as one. It is independently BAuA approved, Fraunhofer tested, QualityLabs certified as antimicrobial, and Dermatest certified “Excellent” for dermatological safety.
What is VireXbuster made of?
VireXbuster uses a proprietary hybrid antimicrobial formulation with a very wide spectrum of activity against viruses, bacteria, fungi, mold and mildew. The exact composition is proprietary to DaXem GmbH.
How long does the antimicrobial protection last?
VireXbuster is designed to provide long-lasting residual protection on treated surfaces, continuing to work between routine cleaning and disinfection cycles rather than requiring reapplication after every touch.
Can VireXbuster be used on walls, ceilings and floors?
Yes. VireXbuster Wall is a waterborne antimicrobial paint for walls and ceilings (not floors). VireXbuster 4Bulk is an additive for polymers and plastics manufacturing, including polymer flooring. VireXbuster Spray is applied as a coating to a wide range of existing surfaces.
Where can I buy VireXbuster products?
The full VireXbuster product range is available through the VireXbuster online shop. For bulk, distribution or manufacturing inquiries, contact the DaXem GmbH team directly.
