For surface disinfection, the question is not only \u201cis the product virucidal?\u201d, but \u201cwhich viruses was it tested against?\u201d. The answer depends on the structure of the virus.<\/p><div style=\"background:#F5F8F7;border-left:4px solid #008B79;border-radius:8px;padding:16px 20px;margin:0 0 24px\"><p style=\"font-family:Poppins,sans-serif;font-weight:600;color:#161E2C;margin:0 0 8px\">In short<\/p><ul style=\"margin:0;padding-left:22px;line-height:1.7\"><li style=\"margin:0 0 6px\"><strong>Enveloped viruses<\/strong> (influenza, coronavirus, RSV, hepatitis B and C viruses, HIV, herpes) have a fragile lipid envelope: they are the easiest to destroy.<\/li><li style=\"margin:0 0 6px\"><strong>Non-enveloped viruses<\/strong> (norovirus, adenovirus, rotavirus, poliovirus) are much more resistant and require a virucidal spectrum demonstrated against them.<\/li><li style=\"margin:0 0 6px\">Check the authorisation for the viruses tested, the standard (EN 14476, EN 16777), the concentration and the contact time.<\/li><\/ul><\/div><h2 style=\"font-family:Poppins,sans-serif;color:#161E2C;font-size:24px;line-height:1.3;font-weight:600;margin:40px 0 14px\">Why the viral envelope matters<\/h2><p style=\"margin:0 0 14px;line-height:1.7\">Enveloped viruses are surrounded by a lipid membrane that is easily destroyed by alcohols, quaternary ammonium compounds or chlorine.
