What Is A Hand Sanitizer?

Hand Rub or commonly known as Hand Sanitizer is a liquid or gel-based solution which is usually used to keep your hands free from germs. Two variants of hand rub are generally available: alcohol-based and non-alcohol based, of which the alcohol-based hand sanitizer is more effective as it works against a variety of disease spreading microorganisms.

Alcohol-Based Hand Sanitizers are usually available in a combination of isopropyl alcohol, ethanol or propanol. If the percentage of alcohol is 65-95%, then it is considered to kill maximum germs. It is the best substitute for soap and water. Hand Sanitizer is more effective than hand washes as it works in mere 10-30 secs and helps in combating many strains of bacteria, fungus and viruses.

Non-alcohol based versions may contain benzalkonium chloride or triclosan. But non-alcohol based hand sanitizer may not be very effective against many types of germs and it just reduces the growth of harmful germs instead of killing them.

How Does A Hand Sanitizer Work? 

Initially, hand sanitizers were developed to use after handwash or when soap and water were not easily accessible. The gel-based sanitizers have more than 65% alcohol content as alcohol is known to have antiseptic properties which kills numerous disease-causing microorganisms present on the surface of the skin. It starts working instantly and kills most of the bacteria, viruses that too in less than 30 sec. Thus,it gives you protection against various contagious diseases. Hand Sanitizer does not kill the human cell but instead, works against microbial cells. It is based on the use of 70% of Isopropyl alcohol which is the rubbing alcohol that conveniently kills the microorganisms or germs present on the skin surface. This 70% isopropyl alcohol is more fruitful than 100% concentration as it has water added to it which makes the absorption easy. Hand Sanitizers work against the virus, by rupturing its outer coat whereas it destroys the bacteria by disrupting its cell membrane.
