E for Ethanol

This is the fifth in the series of 26 posts this month, one post a day, barring four Sundays, each on a theme corresponding to a letter of the English alphabet. The theme this year is "Chemicals in our life", spurred by my interest in chemistry.

This is a chemical compound that is a major component of something that is very familiar to us - alcohol, the common beverage.

In fact, ethanol is also called alcohol, ethyl alcohol, or grain alcohol. 

It is colourless and flammable and has a molecular formula of C2H5OH.

Ethanol is the active ingredient in beverages such as beer, wine, and distilled spirits. It is produced naturally by the fermentation of sugar by yeast or via petrochemical processes such as ethylene hydration. 

Ethanol is used in a wide range of cosmetics like hair styling products, foundations, perfumes and deodorants.

Ethanol is also there in paints, varnishes, lacquers, and pharmaceutical products, of course, in various forms and degrees. 

It has antibacterial, antiviral, and antifungal properties that can kill microorganisms by dissolving their membranes and denaturing their proteins.

It is used in medical wipes, hand sanitisers, mouthwashes, and wound dressings to prevent infections.

In motor vehicles, ethanol is used as a fuel or as a fuel additive. It can be blended with gasoline to form gasohol, which reduces carbon monoxide emissions and improves engine performance. 

Ethanol has a very low freezing point of -114°C (-173°F), which makes it suitable for preserving specimens and organisms that require low temperatures. 

Like all chemicals, ethanol is hazardous. It has psychoactive properties that affect the brain and cause intoxication and euphoria. 

Its excessive consumption can have negative effects on health, such as impairment, addiction, liver damage, and even death by way of alcohol poisoning.

  3. A professor once told me that some chemists just like to imbibe it, since you can't have moonshine without ethanol.

  6. Okay, I maybe had an experience or two with ethanol in college in the form of grain alcohol. If mixed with something like Hawaiian Punch, you can't taste it, and that's very dangerous! :)
