Hand-sanitizers have got hyped a lot after COVID-19 outbreak. A lot of people don’t want to go through the trouble of hand-washing as you can have germ-free hands in 5 seconds.

World Health Organization (WHO) took to social media recently to spread awareness about protecting yourself amid the corona outbreak. On of the topmost advised usage was of sanitizers. It also killed another type of coronavirus i.e. Middle-East Respiratory Syndrome Coronavirus. Doctors recommend alcohol-based sanitizers that too with a concentration of at least 60%. Also, studies show that sanitizers with lesser concentration of alcohol may just lower the growth of germs in place of killing them. Thus, the use of sanitizers with an alcohol concentration of 60-95% is the most effective one.

Analyzing the ingredients of hand-sanitizers

The common ingredients of hand sanitizers are isopropanol, ethanol or n-propanol as the active ingredient; polyacrylic acid or glycerin as the thickening agent; Propylene Glycol, essential oils for scent; Benzalkonium Chloride, Povidone-Iodine or Triclosan as the active ingredient in non-alcohol based sanitizers. Isopropanol, ethanol or n-propanol are all alcohols. So, Ethanol makes it easier for other foreign chemicals to absorb through the skin. Isopropanol is known to irritate the skin.

Polyacrylic acid is used as absorbent material in diapers. Propylene Glycol is a very safe compound that is used as a food additive. Benzalkonium Chloride can cause skin irritation and in a concentration above 0.1%, it can act as a sensitizer. The dangers of the same are known. Povidone-Iodine is rubbed on the skin to sanitize it before going under the knife for operations. So it’s going to be pretty safe and you can choose the alcohol-based one (also, if you like the cool feeling it gives as it is produced by the evaporation of alcohol).
