The most important thing to remember when you are creating your hand sanitizer is to make sure that it is alcohol based. The alcohol solution should be strong enough to kill off the germs on your hands. So, I recommend that you purchase an alcohol solution that contains at least 70% of alcohol to be on the safe side. It’s all about the potency, if it is watered down you won’t get the benefits you are looking for. Secondly, you will need aloe vera gel. You can either purchase the aloe plant and extract the gel or purchase the gel itself. Lastly, you will need an essential oil. Choose an oil that is antibacterial and kills germs such as tea tree oil, lemon, clove, sage and several others.
