They actually do contain high levels of alcohol. For use as protection against Covid, the recommendation was between 60 and 95% alcohol, usually ethanol or isopropanol. The hospital where my wife works had numerous cases of alcoholics stealing and consuming with some requiring treatment afterwards.
