Alcohol Hand Sanitiser Pros and Cons
Hand Sanitiser is also known as Hand Sanitizer the lather being American spelling. There are currently several variations of sanitizers using active ingredients such as peroxides, chlorine-based, BKC and alcohol. For this post we will focus exclusively on alcohol based sanitisers.
Let’s look at the advantages:

- It is not effective against grimy hands. If your hands have dirt or anything else sticking to it, your hands need to be washed before they the hand sanitiser to be effective.
- Some alcohol-based hand sanitisers can leave your hands feeling dry and chapped. If your hand sanitiser doesn’t include a conditioner, chances are, using it leaves you reaching for hand cream.
- People with thin skin may find it too harsh on their skin. Some people with thin weak skin, e.g. people with eczema & babies, may find alcohol-based hand sanitisers too harsh on their skin.
