What myths about detergents should not be believed?

A group of disinfectants

Advantages

Disadvantages

Halide-containing drugs

· a wide spectrum of antimicrobial action: bactericidal, tuberculocidal , virulicidal , fungicidal, sporicidal properties;

· multi-purpose purpose;

· good solubility in water;

· quick action;

relatively low cost

· high aggressiveness towards structural materials;

· high toxicity, pungent smell, irritating effect on mucous membranes of respiratory organs and eyes;

· discoloration effect on fabrics;

· the ability to form environmentally hazardous compounds;

· sensitivity to the action of inorganic and organic substances, temperature, light, pH , etc

Aldehyde-containing preparations

· a wide spectrum of antimicrobial action: bactericidal, tuberculocidal , virulocidal , fungicidal properties, in concentrations of 2% and higher — sporocidal ;

· multi-purpose purpose;

· good solubility in water;

· efficiency when interacting with organic materials;

speed of action;

possibility of use for processing optical instruments (endoscopes)

· increased volatility and the associated need to treat large surfaces with high-concentration solutions in the absence of patients;

· the ability in certain cases to fix organic contamination: blood, mucus, pus, etc., which requires preliminary washing of medical products;

· irritating effect on the skin and mucous membranes

Peroxides, peroxy compounds , oxygen-containing and other oxidants

· environmental safety

relatively low stability, which limits the shelf life of drugs;

aggressiveness towards corrosion-resistant materials;

· high irritant effect of concentrated solutions on mucous membranes of respiratory organs

Alcoholic drugs

· a wide spectrum of antimicrobial action;

· environmental safety;

· short exposure during disinfection;

· absence of residual chemical effect (for example, does not leave stains);

· absence of sediment after evaporation

· the possibility of fixing organic pollution;

· easy flammability;

· swelling and increasing the hardness of plastic, rubber, their subsequent deterioration due to prolonged contact;

· inactivation by organic materials;

rapid evaporation, which leads to a decrease in concentration and prevents long-term contact of objects not immersed in alcohol solutions with the disinfectant

Surfactants

absence of pungent odors;

· low level of toxicity;

· proper level of cleaning properties

· a narrow antiviral spectrum of action;

lack of sporicidal effect at normal ambient temperatures;

· inability to inactivate RNA- containing hydrophilic viruses that do not have a lipid envelope (for example, poliomyelitis viruses, enteroviruses , etc.);

presence of pronounced foaming , which prevents their use in aerosols;

development of resistance in microorganisms with long-term use

Preparations based on guanidine derivatives

· low toxicity

weak effect on tuberculosis mycobacteria, viruses, fungi;

· lack of action on disputes

Phenols

strong fungicidal, virulicidal , bactericidal effect

· lack of action on disputes;

· poor solubility in water

Peracids

· a wide spectrum of antimicrobial action;

availability of high-level disinfection;

speed of action at low concentrations

· corrosive activity;

· strong smell;

· irritating effect on mucous membranes of respiratory organs and skin;

· the need for special measures to protect respiratory organs during the production of working solutions from the concentrate

Meadows

· bactericidal and virucidal properties ( sporicidal effect at high temperature )

· corrosive activity;

· irritating effect on mucous membranes of respiratory organs and skin
