Yeah pretty much what those distributors are offering is guaiacwood essential oil which ranges from amber to green and is extremely thick. The main constituent is valerianol. There are about a hundred different hydrocarbons in it but no guaiol. No one seems to have a clue that what they’re selling as “guaiol” contains anything but guaiol.
So if you’re going to do some R&D, save yourself some trouble and order tech grade synthetic guaiol from Sigma. Otherwise you’re going to have one big mystery soup.
Its metal. I saw an article/interview on it, with the guy who found out about it. they use metal molecules to make it blue. If someone can inform me more please do.
