Of course. You need three ingredients:

* isopropyl or rubbing alcohol (99% alcohol volume)
* aloe vera gel
* an essential oil, such as tea tree oil or lavender oil, or you can use lemon juice instead

Mix the alcohol and the aloe vera in a 2:1 ratio and a few drops of the essential oil or lemon juice. This creates a 60% alcohol solution which, according to the FDA, is sufficient to work as a hand sanitizer. You can experiment with different odour compounds and the amount of which you add to your home-made hand sanitizer.

Do note that if clean water and soap is available, washing your hands with soap is more effective than hand sanitizer.
