I am just starting to dabble at making my own e-juice. I am not looking to get into too big of a debate if flavors in of themselves are safe at all, but looking for feedback on what we think are the safe ones and the types to avoid. I have purchased some flavorless nic (60mg VG base) from RTS. I have also purchased some PG from RTS as well as some VG (glycerin) from CVS. I have mixed up some 50/50 12 mg juice it is nice and clear and it vapes just fine. I also purchased some flavorings from RTS. They are TFA flavors. Maraschino Cherry (PG base) and Toasted Almond (PG Base). I mixed up a batch of the Maraschino Cherry. 12mg 80%VG and 20%PG 10% of the PG is the flavoring and the result is a cloudy juice. First of all I am not sure why the result is cloudy. It has been three days and it still is cloudy compared toe the non flavored batch I made. The flavoring in the bottle RTS shipped is clear (slight yellow tint) and all the bases are perfectly clear. Why are they cloudy when they are mixed together. So I started searching for answers and started finding all types of discussions on what is safe and not safe etc etc. Does anybody have a reference on what to avoid and what seem to be alright to use. I am not trying to make thousands of different flavors just looking for some safe bets. I heard things about avoiding oils, but aren't many of the natural flavors from oils? Very confused. Somebody should right a book.
