This is concentrated flavouring and should be mixed with PG and/or VG and/or additional flavouring before vaping.
Ingredients: Natural and Artificial Flavors, Propylene Glycol, Ethyl Alcohol
Note: This is a rich vanilla flavor that has no Acetoin, Acetyl Propionyl, or of course, Diacetyl. Instead it uses a lesser known custard note called Butyric Acid.
This is the ingredient that other flavor companies are now using to replace Acetoin and Acetyl Propionyl for flavors like Vanilla Custard, and we were asked to create similar substitutions. We want to stress that Butyric Acid can also be a source of irritation to the lungs.
It is still a custard note, but usually is only used in traces, as too much of it can give an unpleasant note to a flavor. Butyric Acid is found in milk, butter, and cheeses. In fact, Butyric Acid occurs at about 2.9% in butter.
