Just got this and it's kind of cloudy. Ingredients say Caprylic/Capric Triglycerides.

Anyone have experience with this flavoring? How safe is this to use?
Caprylic/Capric Triglycerides are similar to glycerin, just usually way thinner -- they're common as diluents for certain flavor volatiles. Funny aside, their name comes from "goat" because the triglycerides are common in goat's milk. Carprylic acid is also known as octanoic acid.
They're the majority of what makes up MCT oil (derived from coconut typically).
The TFA flavor "Frosted Donut" uses these as a diluent.
MCTs aren't lipids -- the body doesn't need lipolysis to break them down for energy.
Mainline Nicotine uses MCTs as a carrier and posted about it here
I've played with MCTs and thought it wasn't wicking very well but I don't see any reason not to vape it. It's not a lipid.
