Which type of alcohol is commonly found in hand sanitizers?

Isopropyl alcohol is commonly found in hand sanitizers due to its effectiveness in killing a broad range of bacteria, viruses, and fungi. It typically has a concentration range of 60-95% in sanitizers, which is crucial for achieving the desired antimicrobial action. Isopropyl alcohol acts as a solvent and denaturing agent, making it suitable for disinfection purposes.

In contrast, butyl alcohol, methyl alcohol, and propylene glycol do not possess the same level of antimicrobial efficacy or safety profile for use in hand sanitizers. Methyl alcohol, for instance, is toxic and can lead to serious health issues if absorbed through the skin or ingested. Propylene glycol, while safe for skin contact, does not have strong antiseptic properties. Therefore, isopropyl alcohol is the preferred choice for formulating effective and safe hand sanitizers.
