I did a lot of experimentation to make a hand sanitizer and found that most things just won't stay together with such high amounts of alcohol. The thickeners separate out and in many cases get very gummy.Anyone have luck actually making sanitizer? I just tried a batch 1 cup 91% rubbing alcohol to 1/2 cup aloe gel. It wouldn't mix, had to put it in a big bottle and shake the heck out if it.
The final product was water thin and so strong alchohol smelling, I don't think any amount of EO would cover it.
I ended up dumping it all. Might as well put straight alchohol in a spray bottle.
Aloe gel is the same way- unless the aloe gel uses a more synthetic thickener that holds up to the alcohol. It will separate too.
My conclusion was that a spray made with alcohol, glycerin, and water is the most convenient, but was also able to make a thin gel with carbopol. I'd shoot for around 70% as an ideal alcohol content.
I tried just about everything I could think of, and most things didn't work. (That includes gums like xanthan and guar, gelatin, agar agar, etc.)
