You only need two ingredients: 2/3 cup of isopropyl alcohol and 1/3 cup of aloe vera gel. Mixed them together and behold, you don’t need to line up at your favorite store to buy a hand sanitizer!
It is your choice to add a few drops (8-10 is recommended by Dr. Helmenstine) of essential oils to give an attractive smell. But adding scent for the olfactory organ is only a secondary reason to add. Because some essential oils like cinnamon, clove, pimento, thyme, oregano, and rosemary have antimicrobial properties, it makes a lot of sense to do the dropping. Although you may become poorer for doing so, adding essential oils make your home product even more powerful to keep you safe.
When done, pour out the mixture into a suitable bottle. Happily inform your friends and love ones about it. If they like your output, it is not at all bad to do business and pocket a few bucks. After all, it is your creation.
