Safety with Essential Oils

So when mixing my liquids I never go above 15% Essential Oils, you can technically go to 20% and be fine but there is no need to. 10% is fine for the my 3 EO mixtures. You should never touch an undiluted essential oil directly if you can help it, and I never ever recommend vaping them undiluted even if it's just a couple drops on top of some sort of dry herb etc. Straight EOs can cause sensitivity reaction when touched even by just skin (which means horrible rashes whenever you come in contact with just the plant), I can only imagine what would happen if you vaped pure EOs without dilution. 

I only dilute my EOs with vegetable glycerin, mine is food grade and certified organic. When preparing EO mixes, I use disposable latex gloves very carefully, I clean my stuff very thoroughly. My preferred method of is using high quality vodka, rubbing alcohol is not safe due to the fumes it puts off and the fact you will be inhaling it/heating it up. I also regularly clean my atomizers, this is because with EOs your atomizers and coil can get gunked up quickly due to the high vegetable glycerin content, the oil from what I understand is relatively thicker than E Cig liquids in general. But it doesn't cause a health problem with inhaling it, since the actual Essential Oils are pretty much watery consistency when you add them, so technically this would just be like a high VG content E Cig Liquid. 

I can't say that for sure though... I have never tried E Cig Liquid, never needed to ever. I have never smoked so I can't weigh in tons there. But people on forums say high VG content can be thicker. I can imagine, sucking that stuff up into a syringe is a pain. 

I carefully store my mixes in amber glass bottles, colored glass (which the brown/amber ones are easier to find and usually less expensive) is the best way to store Essential Oils, so they don't go rancid.

I steep my new mixes for about 36-48 hours, when I first make them, they smell absolutely disgusting and horrid. I would never ever vape them. After shaking (to mix well of course) vigorously for 5 minutes, I let them sit over night. Then the next day I mix multiple times, once again by shaking for 5 minutes each time. By the end of that second night the scent has totally changed and usually they smell absolutely amazing. 

Steeping for regular E Cig Liquids means opening them up and letting them breathe from what I understand, for EO liquids, you don't open them up, just mix them regularly for some minutes and leave them to sit in their bottles while you wait for a couple days. Now in the very first post I made among a lot of other information, I mentioned the preferred temps for EO vaping. 200-220 degrees F is what you want them at. Do not burn more than 250. If you do burn them more for that for a prolonged period, it will burn the EOs and completely ruin the useful benefits they provide.
