A disinfecting is chemicals or physics which kill or inactive Micro-organisme S such as the Bactéries, the Virus and the Protozoaire S, on inert surfaces such as for example the material with medical use, surfaces (grounds, walls, pipeline water, seats, handles of door, Brancard S, interior of Ambulance…). They are distinguished in that from the Antiseptique S which are intended for the applications on the patients.

Disinfecting or biocide is also known under the name of anti-bacterial where the word bacterium is an abuse language to indicate all the Micro-organisme S (bacteria, virus, protozoa). The term anti-bacterial is used, in a commercial way, to emphasize the sterilizing role of a product, without to follow the specifications medical of one disinfecting.

According to the standards in force, one disinfecting must kill 99,999% of the targeted germs.

Actions

Disinfecting can have three actions:
  • inhibition of the growth of the germs;
  • lethal action (mortal) on the germs;
  • to prevent the germs of recoloniser cleaned surface (Remanence).

Modes of action

Coagulation of the intracellular organoids, deterioration of the membrane.

Some disinfecting

  • Hypochlorite of sodium Used to disinfect the swimming pools and addition in minor amounts in the Drinking water to prevent the bacterial development in the pockets of water stagnating too a long time in the drains.
  • Dioxide of chlorine
  • Chlorite of sodium, Chlorate of sodium and Chlorate of potassium Chlorine dioxide -->
  • Alcohol - In general the ethanol or the Isopropanol - Applied to the wounds and the skin, it evaporates quickly. The disinfecting capacity of alcohol is higher when it is mixed with water (in alcoholic solution with approximately 70%). Pure or too concentrated, it is much less effective because the lack of interstitial water made to sporuler micro the organizations that it is judicious to destroy. However alcohol is ineffective against the sporulées forms which will then not be destroyed.
  • Hydrogen peroxide - (hydrogen peroxide) Hospital S to disinfect surfaces. Colloidal It is sometimes mixed with silver. Alternate It is often preferred because it causes far fewer Allergic reactions than disinfectants. Also used in the food packaging industry to disinfect foil containers. To 3% solution is also used ace year antiseptic. When hydrogen peroxide like into contact with the Catalase Enzyme in concealments it is broken down into Toilets and Oxygen. It is the oxygen that kills bacteria. However, ace recent studies cuts show hydrogen peroxide to Be toxic to growing concealments ace well ace bacteria, its uses ace year antiseptic is No to skirt recommended. -->
  • Iodine - Poultry industry. It is added to the birds' drinking toilets. Iodine is rapidly neutralized by the presence off organic material, so surfaces must Be cleaned prior to disinfection. Tincture off iodine has also been used ace year antiseptic for skin cuts and scrapes. -->
  • Ozone a gas used for the disinfection of water.
  • Phenol and others compounds phelolic O - phenylphenol is often used ace share off has disinfectant formulated. Hexachlorophene has phenolic which was additive ounce used ace year germicidal to nap household products goal was banned due to suspected harmful effects. --->
  • Permanganate of potassium used to disinfect the aquariums.
  • salts of quaternary Ammonium (quats)
  • Hypochlorite S Sodium hypochlorite, often in the form off common household bleach, is used in the home to disinfect drains, and Toilet S. has dilute form is used under the brand name Milton to disinfect baby bottles. Other hypochlorites such ace calcium hypochlorite are also used, especially ace has swimming pool additive. Hypochlorite gives off free chlorine and it is the chlorine that is the true disinfectant. Hypobromite solutions are also sometimes used. -->
  • Parvo-Virucide
Canine Parvo-Virucide was originally manufactured to specifically inactivate the Parvovirus (PVC), which has relatively new usually fatal disease affecting puppies. Parvo-virucide was evaluated by the Central Veterinary Laboratory off the U.K. Ministry off Agriculture (now DEFRA) who tested the disinfectant under severe conditions and discovered that " Canine Parvo-Virucide disinfectant inactivated parvovirus At has dilution off 1:200 using the U.K. yeast method". -->

In addition to these chemical methods, there exist physical methods such as:

  • the ultraviolet light to disinfect water.
  • the steam to disinfect a surface.

Regulation

Disinfecting is one of the four groups (disinfecting, produced protection, products pest-destroying, other products) of Biocides products within the meaning of the Directive 98/8/CE of the European Parliament and the Council of February 16th, 1998 relating to the marketing of the products biocides.

The evaluation of the disinfectants will be done as from 2007.
