Menthol and Solubility
Ok...I've been harping all over the forum about my menthol crystals and how wonderful they are, but there is something that I'm wondering. I dissolved the crystals in water, in which they aren't very water soluble and a waxy substance separated from the water, but they are soluble in alcohol. I was reading that propylene glycol is a diol alcohol and was wondering if it would be better to dissolve it in that?
Now, I ordered VG, which is vegetable glycerin and the crystals are not very soluble in glycerin either. I just don't want any of the waxy substance on my atomizer.
Any advise so I can go correct all those posts I made? (Dang newbie)
They seem to do much better dissolving in a PG based juice rather than VG.

Menthol Crystals dissolve in PG very well. especially if you give it a little heat. I put one ~1-inch long crystal in 15ml-20ml of PG, put in the microwave for 4-seconds, swirl it and it is all dissolved in just a few seconds. I use this to mix with a strong (24-36mg/ml nicotine) tobacco flavor or unflavored juice. Works great for me! I have not tried VG yet, but I imagine it would be more difficult to dissolve in VG.
SS, I have not tried VG yet. My guess is mixing the PG-menthol juice with even high concentrations of VG would be OK (remain soluble). Try it with just a small amount of fluid...what do you have to lose? I would love to hear your results.
This weekend I might pick up some VG. I just want to add small amounts of VG to my mixes to see how it increased vapor production.
With menthol mixes I like to add at least 20% of a tobacco flavored juice to kill that Vick's Vapor Rub taste of 100% menthol flavored mixes.
For me, tobacco/menthol mixes taste much closer to menthol cigarettes than tobacco juices do to regular cigarettes. Since I switched to smoking menthols ~6-months before stopping analogs and moving to e-cigs, the menthol-tabacco juice mixes are serving me well. Making my own menthol-PG and mixing with high-test tabacco makes my juice costs about 1/3 of commercial juice.
