 This study developed a new analytical method to detect and measure the concentration of ethanol or isopropyl alcohol in hand sanitizers. The method was tested on 69 samples of hand sanitizers, and it was found that some samples had too much methanol, which could be dangerous if consumed. Therefore, this study provides important information about the safety of hand sanitizers and can help ensure that only safe products are available to the public.
