Professor from the London School of Hygiene and Tropical Medicine in the UK, Sally Bloomfield, said that the products in the market were accompanied by moisturizers. The moisturizer is used to anticipate the harsh effects when alcohol is applied directly to the skin. how about a hand sanitizer that dries quickly, like a 7 second hand sanitizer? and this is what we make glycerin for 3% to dry for 15 seconds, which one is better? and 70% alcohol
Thank you for the question.
To maintain personal hygiene, especially hands, the use of hand sanitizers can indeed be one solution. The hand sanitizer recommended by WHO is one that has an alcohol content of at least 60%. With its contents, this, a variety of pathogenic microorganisms, including viruses and bacteria, can be killed, so that its potential to cause disease can be minimized. It's just that, because of its potentially irritating nature, the use of alcohol as a hand sanitizer should indeed need to be added with a moisturizer. The aim is to minimize the risk of irritation on the skin, such as in the form of skin redness, sore, itching, peeling, blisters, and even swelling.
Alcohol itself is a particle that is volatile. Therefore, repeatedly opening the lid on the hand sanitizer packaging can reduce the work quality. Addition of glycerin can help slow down the evaporation of alcohol, so that the quality of work is more awake. But unfortunately, there are not many studies that specifically test which is better between volatile alcohol and which is not in eradicating impurities and harmful microorganisms. Therefore, any hand sanitizer that is available, as long as it contains more than 60% alcohol, you can actually use it.
It should also be understood, that the use of hand sanitizers is actually only appropriate in urgent conditions, for example when traveling where it is difficult to find clean water sources, when in hospitals or public places where many objects may be contaminated with dirt and harmful microorganisms, and so on. If outside of these conditions, it is strongly recommended to prioritize washing hands using clean running water and soap so that hand hygiene is better maintained.
Hope this helps ...
