The emergence of COVID-19 created confusion between the various terms related to environmental sanitation, making terms such as sanitation and disinfection everyday use among the population. However, consumers did not understand the differences in these terms, leading to confusion in choosing the correct treatment.

Be careful not to confuse Sanitation with Sanitization.


It is the cleaning procedure with water, a product or detergent and scrubbing. Cleaning does not kill bacteria, viruses or fungi, which are referred to as “germs”, it simply removes dirt and other organic materials by washing them away. This allows disinfectants to be more effective and prevents contamination of the environment.


Sanitizing means that the number of germs on the surface is being reduced to a safe level by helping to reduce the bacteria identified on chemical product labels. It doesn’t necessarily clean dirty surfaces or kill germs, but it does reduce the risk of spreading infection. Sanitization remains a mandatory intervention before disinfection and sterilization, because dirt can reduce the activity of disinfectants.


It is the process of disinfecting using chemicals to kill germs on the surface. While it does not clean dirty surfaces, it can remove nearly 100% of harmful microorganisms and pathogenic germs from surfaces and objects.

Disinfectants by law are subject to a harmonized authorization procedure based on scientific evidence and specific proofs of efficacy. The product data, registration/authorization number and detail information regarding efficacy claims and contact time by the manufacture is required in order inform the consumer.

That is why it is important not to confuse a sanitizer with a disinfectant: since while the first simply helps reduce the number of germs on the surface to a safe level, the second kills and acts on a whole series of multi-resistant microorganisms such as bacteria, fungi, viruses, etc.


In medicine, biology, food and pharmaceutical sectors, is a physical or chemical process that destroys all living microorganism. Sterilizers can also act by physical (filtration, heat, radiation) or chemical means.


Disinfectant destroys most pathogenic microorganisms (such as bacteria, fungi, viruses) by physical or chemical means. Products of this type fall under two distinct regulatory processes: medical devices (PMC) and biocides.

The main disinfectants types:

  • Ethyl alcohol
  • Sodium hypochlorite, also known as bleach, amuchin
  • Hydrogen peroxide
  • Quaternary ammonium compounds (QUATs), e.g., didecyl dimethyl ammonium chloride – DDAC, alkyl dimethyl benzyl ammonium chloride – ADBAC.

The factors influencing the action of disinfectants may be internal to the product, such as concentration, stability of preparation and contact time; or external, such as temperature, pH and other characteristics of the material to be treated; or the characteristics of the microbial flora.

In addition to commercial products, there are also disinfectants with so-called “in situ generation”of the active ingredient.

One of the active ingredients generated in this way is represented by active chlorine, which is obtained by electrolysis from sodium chloride, whose “biocidal” effect is given by the balance between hypochlorous acid, chlorine gas and sodium hypochlorite, in variable concentrations depending on pH and temperature. Like active chlorine, ozone, obtained from oxygen, is being evaluated as a biocide.


AMIL Care as a leader in the automated disinfection culture, provides its experience and certified methods to ensure high levels of standards of its treatments according to the needs of the different sectors. Our products are effective, innovative and in line with official regulations.

Based on the experience gained, AMIL Care has understood that research and respect for regulations must go hand in hand with technology to express itself effectively. For this reason, the concept to diffuse liquid substances has been redesigned from scratch following recognized parameters.

In times of great confusion and health crisis, it is essential to rely on those like AMIL Care who give credit to science and endorse their products with certified efficacy studies.
