Im pretty sure its ok, RU seems to disolve pretty damn well in it. Did drink half of the first bottle....f**k me! Never again. Although have a shot of it after a few pints and double vodka's+RB... wierdly enough seems to KO you far more, then if you just drink loads of it on its own from sober
Not that i'd recommend it, and it wont do ur hair any good!
The container in the picture doesnt look the same as the one that was there when i bought it, however the CAS Number matches up with the one on the bottle ive got. I bought the 500ml bottle.
Also on the one i have it says Pharmacopoeia Grade, on the page linked above it says
Food Grade - Fragrance Grade
tis still 99%+ as far as i can tell, so should be the same stuff. Im pretty sure this is the right PG to use, although if it's not can someone enlighten me
