Ozone and hygiene

What is Ozone?

O3 is an antimicrobial agent that exhibits high reactivity, penetrability and spontaneous decomposition into pure oxygen.

These characteristics make it an unmatched disinfectant. It has the power to inactivate bacteria, molds, yeasts, parasites and viruses.

It is composed of 3 oxygen atoms arranged to form a resonance hybrid; this particular chemical structure explains the reactivity of the molecule and its behavior at the biological level.
It is characterized by a pungent odor, the same that sometimes accompanies thunderstorms, due to the ozone produced by lightning discharges; it is an essential gas for life on Earth and is formed by natural phenomena, such as lightning and UV rays at 185 nm. When stimulated by an electrical charge or ultraviolet (UV) light (specific wavelength), the oxygen molecule (O2) breaks down and temporarily binds to other oxygen molecules, forming ozone (O3). All ozone molecules are chemically identical, each containing three oxygen atoms.

  The ozone layer is a key shield for intercepting radiation that is lethal to life on Earth. The ozone layer absorbs almost all harmful ultraviolet radiations, in particular those called UV-B at 95% and totally UV-C, but it allows UVA rays to pass through almost completely, i.e. those that cause the most damage to the epidermis. So, if the layer shrinks, the amount of radiation reaching the earth's surface increases. These radiations, in minimal quantities are not harmful, indeed they are useful: for example, they are important in our formation of vitamin D. At higher doses, however, these ultraviolet rays have deleterious effects on the whole life of microorganisms, animals, plants, even plastics are affected by their effects.

This is why we talk about the problem of the "ozone hole", that is the reduction of the thickness of the ozone layer in the earth's atmosphere caused by the release of some pollutants by man deriving from production and consumption activities.

In the absence of human activity on the Earth's surface, ozone would still be present near the surface and throughout the troposphere and stratosphere as it is a natural component of the clean atmosphere.  


Active Oxygen is an extremely reactive species and reacts very selectively with the macromolecular components of bacterial cells, fungi, protozoa and viruses.


Unlike most chemicals used for these purposes, it has no natural resources or conservation methods. It is generated on site and since it has a rapid decomposition, it cannot be stored for long periods of time, therefore it needs a generation plant every time it is necessary to use it.

Other uses of ozone

In addition to sanitizing and sanitizing in depth, ozonated water is also perfect for washing the nose, the oropharyngeal cavity and the private parts.


Another important field of application is at the cutaneous level, ozone not only makes the skin more luminous and elastic, but is also a valid aid against fungal infections of the skin, athlete's foot, vaginal candidiasis, impetigo, psoriasis, dyshidrosis and other pathologies.


The benefits also extend to the sanitization of food: washing fruit, vegetables and meats allows to break down the bacterial load and the contaminants present in them. It is in fact approved by the Ministry of Health and the FDA (Federal and Drug Administration) as a food preservative due to its bactericidal and effective capacity.

Ozone is also used on an industrial level, specifically by paper mills for the treatment of cellulose, in metallurgy for ferrous removal, in the pharmaceutical sector for protein systesis, photochemistry and the production of sterile water, not contaminated by microorganisms and in the textile sector for bleaching fabrics .
