Disinfectants are antimicrobial agents that
are applied to the surface of non-living objects to destroy microorganisms that
are living on the objects.
Disinfection does not necessarily kill all
microorganisms; it is less effective than sterilization. They work by
destroying the cell wall of microbes or interfering with the metabolism.They
are frequently used in hospitals, dental surgeries, kitchens, and bathrooms to
kill infectious organisms.
PROPERTIES
A perfect disinfectant offers complete and
full microbiological sterilization, without harming humans and useful form of
life which are noncorrosive. However, most disinfectants are also, by nature,
potentially harmful to humans or animals. Most modern household disinfectants
contain Bitrex, an exceptionally bitter substance added to discourage
ingestion, as a safety measure. Those that are used indoors should never be
mixed with other cleaning products as chemical reactions can occur.
The
choice of disinfectant to be used depends on the particular situation. Some
disinfectants have a wide spectrum while others kill a smaller range of
disease-causing organisms.
TYPES
OF DISINFECTANTS
·
Air disinfectants are typically
chemical substances capable of disinfecting microorganisms suspended in the
air. An air disinfectant must be dispersed either as an aerosol or vapour at a
sufficient concentration in the air to cause the number of viable infectious
microorganisms to be significantly reduced.
·
Alcohol and alcohol plus
Quaternary ammonium cation based compounds comprise a class of proven surface
sanitizers and disinfectants. The efficacy of alcohol is enhanced when in
solution with the wetting agent.
·
Aldehydes, such as formaldehyde
and glutaraldehyde, have a wide micro biocidal activity and are sporicidal and
fungicidal. They are partly inactivated by organic matter and have slight
residual activity.
·
Oxidizing agents act by
oxidizing the cell membrane of microorganisms, which results in loss of
structure and leads to cell lysis and death. A large number of disinfectants
operate in this way. Chlorine and oxygen are strong oxidizers.
APPLICATIONS
Disinfectants are important chemicals used
for a variety of purposes. Within homes, they are used to kill microorganisms
which can grow in places such as the kitchen or the bathroom. They are widely
used within the medical establishment, hospitals, health care centres and
doctors' offices for purposes of killing different types of germs which may
cause different kind of diseases.
Disinfectants can kill germs and
microorganisms which may not be seen with the naked eye. For instance, Phenolic
types of disinfectants are very good for killing bacteria. They are considered
as general purpose disinfectants, and can kill organic matter.
