OK first 240ml test worked OK. I added Aloe (bottled) instead of topping off with sterile Distilled Water hoping it might thicken a bit. While looking for specific gravitys, I read details about Hydrogen Peroxide. The Aloe had citric acid as a preservative and I’m not sure what got cloudy and separated, but eyeballing volume-wise (the visible layer settles over time) the Aloe is an easy guess. Perhaps was denatured by the concentrated (91%) alcohol, or reacted with the hydrogen peroxide (?) Also could be from adding oil.
I had some Lavender Orange essential oil which makes it so awesome. It feels (soft hands!) and smells great after the alcohol evaporates. Speaking of alcohol smell, I’m pretty sure there is quite a bit of evaporation in your old bottle of Purell, because stuff I have used from various places (and my own ancient bottle from my car console) doesn’t smell as strong as my own fresh batch …which is carefully calculated to 75% v/v. Maybe don’t rely on it soo much (label states to never store over 110 degrees F like in your car?), or add a little alcohol yourself (for insurance) …of course we’re talking 190 proof Everclear or 91% Isopropyl.
So next question. What are they adding to hand sanitizers to make that pudding-ey gel? I would think it might help it stay in place more effectively, but at the same time, what’s that junk doing drying on your hands? My watery stuff definitively does the job, but you just can’t make a little controllable mountain of it in your palm, so application is a bit “splashy”. I can read the ingredients on the back of my Purell, but it’s not helpful in terms of stuff I can procure (looks like some vitamin E?). Maybe I should not care …just so curious (DIY-itis~!) I mean I did make a half-pint for like 39 cents.
Gel ingredient? Anything I can find in my kitchen? When warmer weather hits I’ll be able to get some Suntan product type aloe gel, but I don’t think it’d work as an about 10% add to gel up a whole batch
