| Summary: | Fourier transform infrared spectroscopy (FTIR) is a fast and non-destructive analytical method. Combined with chemometrics, it is a powerful tool for the pharmaceutical, cosmetics and food industries. This method can be used for qualitative and quantitative analysis of medicines, foods and other daily products. At the same time, IR spectroscopy is becoming a suitable technique in the processes of drug preparation and for monitoring the productive processes in quality control laboratories. In this paper, IR spectroscopy is used to determine the concentration of alcohol in hand sanitizers, which is essential for slowing the spread of viruses. The effectiveness of hand sanitizer is entirely determined by the volatile ingredient, alcohol, which must remain at a concentration greater than 60\% (volume) to destroy bacterial and viral pathogens. The selected samples varied according to the initial concentration of ethyl alcohol, manufacturer, color, perfume and other ingredients, as well as the validity period.
