HAND SANITISER VS WASHING HANDS

Hand sanitiser/hand antiseptic is a liquid or gel-based product designed to kill or inhibit the growth of microorganisms on the hands. It is used as a convenient alternative to hand washing when soap and water are not readily available or feasible.

Hand sanitisers typically contain a high concentration of alcohol, such as ethanol or isopropyl alcohol, ranging from 60% to 95%. The alcohol acts as the active ingredient that kills a broad spectrum of bacteria, viruses, and some types of fungi on the skin's surface. Hand sanitisers can also contain other ingredients including water, moisturisers (glycerin), emollients (aloe vera) and fragrance.

Are hand sanitisers a good replacement for hand washing and when should they be used? 

Hand sanitisers should not be considered a substitute for hand washing because they are unable to effectively eliminate dirt, grease, or other debris from the skin and nails. As a result, washing hands with soap and warm running water is the recommended and preferred method. Nevertheless, using a hand sanitiser after proper hand washing can provide an additional layer of protection.
