It is a common question that people ask, if a certain chemical is OK to use for extraction or not, and also where to find such and such chemical. Instead of cluttering up the forum with hundreds of threads about it, those who have these question can post here (and threads made with such questions will be merged here).
But before asking such questions, here's a few important links you should THOROUGHLY read:
Check what your solvent contains here thread
FAQ: Is my solvent/chemical OK to use ?
The Suppliers section

... Btw just a note for Tolki !!! As i am coming from the same country i can only tell him that he is lucky he is living there as most of the solvents can be found quite pure from a chemical supplier here.The prices are high compared to the standard we have here, but it will not hit your pocket hard if you extract for your own personal exploration.
