Purity - What is the SD on "denatured" GBL?

[unico_walker]

There seems to be the common idea that companies have begun "denaturing" GBL to eliminate its abuse potential.

Now mixing other solvents or NMP seems obvious but several people have
said that even if you boil off the other solvents like a certain polish
remover that has GBL and acetone it is impossible to feel effects from
the GBL or use it in a synthesis.



Whats going on here? I find it hard to believe that chemical companies
have found a way to make non-fun GBL,but its a popular idea on the
newsgroup.
