Okay, apparently it's made by a company called "Murica," and I'm not having much luck finding the ingredients right now, but for their "Snozz Creme," I came across

Flavor goes bad in tank too quick, June 10, 2017
Reviewer: Paulie from NY
I am not sure if its the flavorings or the high VG.. but i have to change my wick on my kayfun mini v3 everyday or twice a day.. At first the flavor is good, it taste kind of like a raspberry razzle candy with some creaminess. Throat hit is kind of weak which is another thing I don't like. but what kills it for me is that the flavor takes a dive very quick and I get an almost burnt taste from the juice. I might just get rid of it.
So it seems that there is an issue with the Snozz Creme, at least, for some. Too much sweetener in an e liquid can definitely gunk up coils quickly and cause a burnt taste, and high VG can also contribute if the wick/coil isn't able to absorb the liquid efficiently for the rate of vaping or the wattage used.
Of those issues, pretty much all you can really try is lowering wattage, and making sure you aren't chain vaping too strongly to see if that makes a difference ... or cutting your juice with more plain PG, possibly, but that will dilute the flavor, and is probably not a very useful idea unless it seems overflavored already.
I hope someone with direct experience can help more!
