The use of hand sanitizers is one of the important measures recommended by the Centers for Disease Control and Prevention to prevent the spread of diseases. The main component of hand sanitizers is ethanol, and its concentration should be greater than 60% as regulated. Several spectroscopic techniques have been developed to determine the actual ethanol concentration in sanitizers. One such method involves measuring the frequency of a specific vibrational mode of ethanol, which is proportional to its concentration. In this study, Raman and Brillouin spectro-scopies were used to investigate seven hand sanitizers, and the results were compared with those of pure ethanol-distilled water (subsequently referred to as ethanol-water) solutions. The results showed that the mode frequency of the CCO stretching vibration of several sanitizers deviated from the fitted line, indicating that the actual ethanol content in these commercial products differed from the values stated on the product labels. Additionally, the concentration deviation was correlated with an anomalous increase in the sound velocity. This suggests that acoustic methods may be used as an additional tool to investigate the actual ethanol concentration in commercial hand sanitizers.
