“Sanitizing”, “antibacterial”, “disinfectant”, “virucidal”, “kills 99.9% of germs”: on the shelf, they all seem to promise the same thing. They don’t. Some products only clean, others have proven in the lab that they destroy certain viruses within a specific time, and the difference isn’t in the color of the bottle but in a few lines on the label.
This guide explains what each term means, who regulates these products, how to read the “virucidal” claim (not all virucides cover the same viruses), what “log” reduction means and how to recognize a product that only sanitizes. At the end you’ll find the right products from the Prima Shop catalog, grouped by what they actually do.
These four words describe different levels. Each step usually assumes you have gone through the one before: you can’t effectively disinfect a dirty surface, because dirt protects microorganisms.
“Sanitizer” is not a legal category in the European Union. On a label it can mean an ordinary detergent, a cosmetic soap or a scented gel. In the US, the equivalent term (“sanitizer”) has an official definition, which explains part of the confusion.
| Product type | Legislation | Can it claim to destroy viruses? | What you see on the label |
|---|---|---|---|
| Detergent, cleaning product | Regulation (EC) No 648/2004 | no | Composition, directions for use |
| Cosmetic (soap, hand gel) | Regulation (EC) No 1223/2009 | no | INCI ingredient list, responsible person |
| Biocidal disinfectant (TP1, TP2, TP3, TP4) | Regulation (EU) No 528/2012, CNPB authorization | yes, for what it was tested against | Authorization, active substance and concentration, spectrum, EN standards, contact time |
| Medical device disinfectant | Regulation (EU) 2017/745 | yes, for what it was tested against | CE marking with the notified body number |
In Romania, biocidal products are authorized by the National Commission for Biocidal Products (CNPB), and the list of authorized products is public. TP1 means human hygiene, TP2 surfaces, TP3 veterinary hygiene, TP4 food contact areas.
From a disinfection standpoint, viruses fall into two main groups. Enveloped viruses have an outer lipid membrane that alcohol and detergents easily destroy: influenza, coronaviruses, HIV, hepatitis B and C viruses, herpes. Non-enveloped viruses are much more resistant: norovirus, which causes gastroenteritis, adenovirus, rotavirus, enteroviruses, poliovirus and hepatitis A virus.
That is why the European standard EN 14476 doesn’t have a single “virucidal” claim, but three levels:
| Label claim | Tested on | Covers | Suitable for |
|---|---|---|---|
| Active against enveloped viruses | vaccinia virus (MVA) | enveloped viruses only | Influenza, COVID-19, HIV, hepatitis B and C |
| Limited spectrum virucidal | adenovirus and murine norovirus | enveloped + adenovirus, norovirus | Viral gastroenteritis, adenoviral conjunctivitis |
| Virucidal (full) | poliovirus, adenovirus and murine norovirus | almost all viruses | Hospitals, outbreaks, high-risk areas, enteroviruses |
Laboratories measure a disinfectant’s efficacy in powers of ten: how many microorganisms remain active out of an initial number after the contact time. Each “log” means ten times fewer. For one million microorganisms:
So “kills 99.9% of germs” means 3 log. For a professional disinfectant, the threshold required by the standards is usually higher, and the claim only matters if it also states the standard, the microorganisms and the contact time in which the result was achieved.

| Situation | What you need | Keep in mind |
|---|---|---|
| Daily cleaning at home | Detergent, soap, water | Disinfectant doesn’t replace cleaning |
| Someone at home has influenza or COVID-19 | Disinfectant active against enveloped viruses | Door handles, light switches, phones, bathroom |
| Gastroenteritis, norovirus | Limited spectrum or full virucide, or a chlorine-based product | Alcohol alone is weak against norovirus |
| Hands in the practice | TP1 disinfectant tested to EN 1500 | With EN 14476 for the required viral spectrum |
| Surfaces between patients | Fast-acting TP2 disinfectant, EN 14476, ideally EN 16615 | Ready-to-use or wipes |
| Hospital, outbreak, isolation area | Full virucide, possibly also sporicidal | Clostridioides difficile requires a sporicide |
| Kitchens, food industry | TP4 disinfectant, EN 1276, EN 13697 | Rinse, if the label requires it |
Cleaning products and cosmetic soaps aren’t “weaker”; they have a different role: they remove dirt, grease and a good share of microorganisms, and prepare the surface for the disinfectant. Proper handwashing with soap and water remains mandatory when hands are visibly dirty.
Virucidal disinfectants for surfaces and hands, cleaning products and soaps, with technical data sheets and authorizations, invoiced to your company.
A gel with at least 60–70% alcohol usually works against enveloped viruses. Without testing to EN 14476 and without a biocidal product authorization, however, you have no guarantee regarding concentration, contact time or spectrum. In practices and hospitals, use a tested TP1 disinfectant.
They have no proven efficacy as disinfectants and are not authorized for this purpose. They are useful for cleaning, for example for limescale or grease, but they don’t replace a disinfectant.
Sodium hypochlorite solutions at the right concentration also destroy resistant viruses, including norovirus. However, products sold as detergents don’t have tested and authorized dilutions and contact times. If you use them, follow the label, ventilate the area and never mix them with acids or ammonia.
A 3 log reduction, meaning that out of one million bacteria, one thousand remain. The claim says nothing about viruses, nor about the conditions under which the result was achieved, unless it states the standard and the contact time.
It depends on the product and the surface. On surfaces that come into contact with food or with children’s skin, many products require rinsing after the contact time. The instruction is always on the label.
No. For hands and skin, use only TP1 products or antiseptics made for living tissue. The difference is explained in detail in the guide to disinfectants and antiseptics.
