I can find no studies on Glycerin as a fog material. All studies are on the newer Glycols.
That does not mean it is unsafe, however I'd limit my exposure or use it outdoors.
I used to work with Chemists and Physicists at a major applied technologies lab. There are often slight variations on molecules, and sometimes what is in the bottle is a little different then the simple explanation, example: It is not always pure, can't exist in a pure state, has a isomer, has additives to stabilize it, and so forth. So I am always cautious to check what is actually in a bottle.
Most countries have a "Pharmacopia" which is a list of approved recipes for drugs and topical medications. Often the Pharmacopia requires additives to the pure material.
So one has to check the Pharmacopia to see what is in the drug store chemical.
