Disinfectants: knowing the differences to choose the most suitable one

As we have seen in the article on sanitizing and sanitizing are different actions that require specific tools and detergents. Cleaning and removing the dirt deposited on the surfaces is the first step to effectively carry out the hygiene measures that should actually be carried out after cleaning in order to achieve a truly effective and lasting result.

Solvents, detergents, disinfectant soaps, there are now such a variety on the market that it is difficult to find your way around choosing the right product for us.

In fact, each product has its specific use, certainly there are also multi-use cleaning products but here today we want to focus on the different formulations and their characteristics.

We assume that Disinfect means carrying out those operations necessary to eliminate a percentage of around 99% of potentially pathogenic bacterial loads.

Let's see what the Italian law specifically says:

  • 'Cleaning activities are those that concern the complex of procedures and operations designed to remove dust, unwanted material or dirt from surfaces, objects, confined spaces and areas of relevance;'
  • 'Disinfestation activities are those that concern the complex of procedures and operations aimed at destroying small animals, in particular arthropods, both because they are parasites, vectors or reserves of infectious agents and because they are bothersome and unwanted plant species.'

(MINISTERIAL DECREE 7 July 1997, n. 274 'Implementation regulation of articles 1 and 4 of the law 25 January 1994, n. 82, for the regulation of cleaning, disinfection, disinfestation, rodent control and sanitation')

Acting in depth, but not reaching the level of disinfectant products can also be products for cosmetic purposes and not PMC . A product marked P.M.C. must bear a registration number, imperatively present on the packaging, which guarantees its authenticity and the examination by a qualified body that can define it as a PMC, since it conforms to the predefined sanitary standards.

Let's see some of the main types of disinfectants:

Sodium hypochlorite (NaClO): also present on the market as Varechina, Amuchina or Bleach in concentrations ranging from a minimum of 1.5% to a maximum of 10/15%, it has a good disinfectant efficacy on a wide spectrum of bacteria, viral agents, molds and spores . Above 15% bleach is corrosive and should always be used with extreme caution. We recommend that you always use gloves during cleaning and even more so when using these products, very important: NEVER mix solvent products together, bleach together with ammonia, for example, releases toxic and extremely irritating amounts of chlorine.

Ethyl and isopropyl alcohol: cheap and easily available, it is a good disinfectant at concentrations between 60% and 75%, also used on intact skin and has a good disinfectant capacity. There is also isopropyl alcohol (or iso propanol) with antiseptic properties slightly higher than those of ethyl alcohol. It is not marketed in pure formula, unlike ethyl alcohol, but only diluted in other solvents. Extremely flammable, they have the advantage of having multiple uses and broad spectrum antiseptic functions.

Hydrogen peroxide: it is also easily found in large-scale distribution stores, it is slightly less effective than sodium hypochlorite but has the advantage of working better at low concentrations, as the bactericidal action persists over time. Above 35% concentration it becomes corrosive, attention: if the product degrades it releases carbon dioxide inflating the container.

Quaternary Ammonium Sali: the products composed of quaternary ammonium salts in low concentrations have a good bactericidal power, by denaturing the proteins they inhibit the metabolic processes of micro-organisms and alter their external membrane, therefore they are excellent against bacteria but also viruses and algae. Not very effective on molds and spores. It has the advantage of being less toxic than the previous ones, but it must be used with some precautions: first of all it must not be diluted with soap and never use or wash the surfaces with soap after using ammonium salts, the latter in fact are 'deactivated' as antiseptics from anionic surfactants such as common detergent soaps. It also tends to develop a form of resistance, so it is good to rinse well after use and alter the ammonium salts other disinfectants such as alcohol or the others we have talked about, viruses and bacteria in fact tend to develop a form of resistance to this substance, therefore after its use it is necessary to rinse well so as not to allow the surviving micro organisms to 'get used to' and develop defenses to ammonium salts.

Our PMC cleaners:

Pharmaform 5 L: based on ammonium salts, ethyl components and chlorhexidine, it has a broad and effective disinfectant power. This is why it can be used to sanitize different surfaces in contexts potentially at high risk of contamination. It is diluted in 5% water (50 ml in a liter of water) in the practical 5 L package, it is perfect for even frequent sanitation operations.

LH Ambiente 5 L: always based on ammonium salts, it has a broad spectrum of action by acting on bacteria and viruses. It dilutes well in water and is excellent as a disinfectant even on pre-wash clothes and dishes.

Our other disinfectants:

Saniclor spray: based on Sodium Hypochlorite, it has an excellent disinfectant action on all washable surfaces, even the most delicate

M-15Oxi: disinfects surfaces with hydrogen peroxide respecting the hygiene criteria of the HACCP protocol

Igienplus: with chlorhexidine gluconate and propyl alcohol, it is an excellent broad spectrum disinfectant which, if used correctly, does not even require rinsing, even Igienplus is ideal in environments that require products consistent with HACCP regulations.
