don't looking for this now I am sure if a chemical can be used to make any kind of explosive its highly regulated here.
or it comes on the market in a form you can't used anymore. ammonium nitrate for example know to be an explosive together with fuel oil - ANFO - and widely used as a fertilizer is mixed with chalk it don't work this way.
no, they don't forget anything also the simple potassium permanganate is not easy to get for years now.
