The most important parameter to consider in compounding hand sanitiser is the alcohol content. It has also been determined that hand sanitiser with alcohol concentration below 60% (v/v) is not effective and could leave the user at higher risk of infection. This application note describes the use of FT-IR spectroscopy to determine ethanol and isopropanol in hand sanitiser.
