Top 5 Chemical Disinfectants Used in Hospitals

Hospitals use numerous ways and means to prevent the spread of infection, and using the best disinfectants is of the utmost importance in achieving this purpose. Healthcare professionals can use an array of disinfectants to clean surfaces and equipment. However, knowing the most effective ones that can provide the best result is the key. This blog will discuss the top 5 disinfectants used in medical centre cleaning.

Most Common Types of Chemical Disinfectants

1. Alcohols 

Alcohol, a common disinfectant, is used in hospitals as an effective agent against various microorganisms, including bacteria, viruses, and fungi. However, they are not efficacious against spores. In healthcare and pharmaceutical setups, alcohol refers to ethyl alcohol and isopropyl alcohol, two water-soluble chemical compounds that medical professionals use

as antimicrobial agents. 

Alcohols have also been used as hard surface (nonskin) disinfectants in healthcare settings as they possess many desirable features for disinfectants or antiseptics. Due to this, expert cleaners use alcohol as a hard-surface disinfectant because of its general antimicrobial properties. Although, the volatility and flammability of alcohol could cause an issue. Ethanol and propanol have flash points below 15°C, requiring caution in usage to avoid it. 

2. Phenols 

Phenols are another type of disinfectant commonly used as effective against various bacteria, viruses, and fungi. Phenol is an antiseptic and disinfectant, and cleaners in Manly use it as a cleaning product in medical centres and other premises. As per FDA, phenol concentration is a high-level disinfectant containing 1.12% glutaraldehyde and 1.93% phenol/phenate.

Thus, exposure to phenol could irritate the skin, eyes, nervous system, nose, or throat. Weight loss, weakness, exhaustion, muscle aches, and pain are some symptoms of exposure to phenol. Moreover, severe exposure could cause liver, and kidney damage, convulsions, skin burns, tremor, and twitching.

3. Chlorine 

Chlorine, a potent disinfectant, is widely applicable and very effective in pathogen deactivation. It can be easily applied, measured and controlled; it is persistent and affordable. People have used chlorine for applications such as the deactivation of pathogens in drinking water, wastewater and swimming pool water and for the disinfection of household spaces, textile bleaching, and much more over hundreds of years.

It breaks the chemical bonds in the molecules and kills pathogens such as bacteria and viruses. It also disinfects surroundings and is widely applicable for cleaning purposes in various residential, commercial, medical facilities and other spaces. Healthcare professionals commonly use chlorine in medical cleaning for sanitising and disinfecting surrounding regions of healthcare premises. 

4. Iodine 

Iodine is a potent disinfectant used in medical centre cleaning. It is an effective disinfectant for viruses and bacteria. There are many advantages of using iodine sanitisers – healthcare professionals can use them at much lower pH levels, making them less corrosive than chlorine. However, the efficacy of iodine sanitisers is temperature-dependent, implying iodine becomes very caustic at high temperatures (above 80 degrees Celsius). But, healthcare professionals use povidone-iodine as one of the most commonly used surgical scrub preparations. According to a study, a scrub of at least 3 minutes is crucial for effective disinfection.

5. Hydrogen Peroxide 

Another disinfectant healthcare professionals use as an effective agent against various microorganisms is Hydrogen Peroxide. It is an inexpensive and effective disinfectant with relatively few disadvantages. Moreover, numerous studies provide data on the concentrations and durations of hydrogen peroxide, effective against certain organisms. It is the best choice for manual disinfecting.  

Hydrogen peroxide is a sustainable and affordable disinfectant. It is stable in normal circumstances. When stored correctly, the decomposition or loss of potency in small containers is less than 2% per year at ambient temperatures, implying hydrogen peroxide has a longer shelf-life without significant loss. 

Hydrogen peroxide is the most effective and sustainable disinfectant to clean and kill bacteria, fungi, viruses, and spores. It has proven time and time again to be superior at disinfecting surroundings. Healthcare professionals must choose hydrogen peroxide in cleaning patients within a hospital or any healthcare building. 

Wrapping Up 

Healthcare professionals use many disinfectants alone or in combinations (e.g., hydrogen peroxide and peracetic acid), including alcohol, chlorine and chlorine compounds, formaldehyde, quaternary ammonium compounds, etc. Moreover, the commercial formulations based on these chemicals are unique and registered with the respective authority. Such products serve specific purposes and have a unique manner of use. Therefore, healthcare users should read labels carefully to ensure the correct product is selected for the intended use and applied efficiently.

As disinfectants are not interchangeable, incorrect concentrations and applications result in additional expenses. Moreover, healthcare personnel must use various measures such as gloves and proper ventilation to avoid occupational hazards among healthcare workers.
