Ethanol or isopropyl alcohol?  

CP Industries Ltd product is made from isopropyl alcohol

The World Health Organization (WHO) states that disinfecting surfaces like tables and door knobs and disinfecting hands with the use of alcohol is a must to avoid the spread of Coronavirus (COVID-19).

The WHO strongly encourages people to take steps in protecting themselves from the virus, such as practicing good hand hygiene and good respiratory hygiene.

When it comes to disinfecting with alcohol, which would you prefer to use – ethanol or isopropyl?

These two alcohols are essentially the same when it comes to disinfectant properties. They do, however, have slight differences when rubbed on the skin.

Ethanol (sometimes called Ethyl) is the type of alcohol present in alcoholic beverages. Isopropyl alcohol is also known as isopropanol, 2-propanol or rubbing alcohol. When used as disinfectants, both are typically at a concentration of 70% in water.

Ethanol works by denaturing proteins and dissolving lipids, effectively destroying many types of bacterial and viral cells. It is ineffective against spores.

Ethanol is typically used in concentrations of 70% because higher concentrations evaporate too quickly and lower concentrations are not as effective. It is present in some soaps and hand wipes, but it is capable of drying out skin thus, should not be used directly without additional agents.

Isopropyl, on the other hand, evaporates at a similar rate and destroys bacterial and viral cells by the same mechanism. It is not, however, as effective at dehydrating living tissue and so is a better solution for disinfecting skin than ethanol. Isopropyl alcohol is often used as an antiseptic for this reason.

A study comparing the effectiveness of an ethanol-based cleanser (EBC) with isopropyl alcohol pads in reducing bacterial contamination of stethoscope diaphragms led health experts to believe that cleaning with EBC and isopropyl alcohol pads significantly reduced the colony-forming units (cfu) counts (by 92.8% and 92.5%, respectively), but neither was found to be statistically superior.

Cleaning a stethoscope diaphragm using either EBC or isopropyl alcohol led to a significant reduction in bacterial growth in culture.

For disinfecting surfaces, ethanol and isopropyl alcohol are similarly efficient. Ethanol may be used in purely surface-cleaning applications, but isopropyl alcohol can also double as antiseptic and is commonly used in hospitals.

Both are most effective at 70% concentration and can be used to clean small tools if they are immersed for about 10 minutes. Both evaporate quickly, without leaving a residue, and are effective for cleaning optic drives and computer components.

Both alcohols are capable of dissolving lipids, which makes them effective against lipid-wrapped viral cells such as HIV and hepatitis A. They are inexpensive and relatively easy to handle, although their vapors are flammable.

But the most important of all is to rub the alcohol while applying it to make it more effective.
