drop of PI contains about 12 mcg None (as far as I know). But the secret incredient in NPA and the different carrier
NPA (-> alcohol) and PI (-> oil) makes me unsure.
My next question concerns what kind of PI I should I buy -
the scented or the unscented version? what would you suggest me?
Last question: How works the chemset-None
compared to the PI - anybody can tell me about?
Thanks :)
