I knew VG had such properties, but is there some study that validates or inclines such a statement? Very interesting indeed.
Somewhat true. I am not quite sure if the same can be said for PG (Propylene Glycol) I know that VG (Vegetable Glycerin) is metabolized into H20 and C02. Here's some light reading on a study done with VG when inhaled through an atomizer: Safety of VG when inhaled through an e-cig
e-liquid, however, does contain more than just VG. Nicotine if you have it. Flavorings. The last one is probably the most questionable, and as such, the quality and safety of the liquid you use can only be weighed by the professionals and tools/labs they create it in. I wouldn't recommend buying juice on eBay. Not only does eBay not allow such sales, but you have absolutely no way of knowing what you are vaping.
Check out: Velvet Cloud Vapor They make organic juices (using natural flavoring) and even put an ingredient list on their bottles! I'm enjoying some of their Nutty Cookie right now!
P.S. That Vapage U-Turn is indeed an eGo Twist / Vision Spinner. Just another variant of the same thing. They're easily one of the most popular and highly recommended devices for vaping.
Vape well, vape often

Really, if you search VG or PG + antibacterial or antimicrobial and you'll get plenty of hits leading to a variety of published studies.
