Hand sanitizer disappears when rubbed on your hands because the alcohol and other volatile components evaporate. As you apply and rub the sanitizer, the friction and heat increase the evaporation rate, turning the liquid into vapor. This process removes the sanitizer from your skin as it evaporates into the air, leaving your hands dry and sanitized. The evaporation is a key step in its effectiveness as it helps eliminate germs.
