Limited water solubility.
The Perfumers Apprentice (also known as Flavour Apprentice) range of flavour concentrates are reputated to some of the best flavourings in the vaping world. These are water soluble and use Propylene Glycol (PG) as the flavour carrier (unless otherwise shown). Having one of the biggest Perfumers Apprentice flavour ranges in the UK and having many eliquid vendor clients among our customer base, we can say that most UK purchased eliquids contain flavours from this range.
With low 10ml bottle prices and even more savings when buying in 30ml, this is a perfect flavour base for those of you starting to experiment in the mixing world.
Please note that Perfumers Apprentice flavours are "Food Grade" and approved by the US FDA. While "generally regarded as safe" for vaping, they have never been approved by any International body for this purpose and as with any our products sold on site, to use them for vaping is done so at your own risk.
