Well I am having a balls of a time with swan atm (Aye, I blame the lighter fluid when I think it's actually the bark not been powdered down just enough, blunt blades on grinder lol) so I think I will try some of this Betaclean 3350 Kerberos mentioned next time.

Seems easily purchased

Just ordered some more ZenSpice Got over 600mg clean spice out of two 50ml pulls with this on a Cyb salt tek with 50g of bark. I will also be posting a link to a UK suppler of Isohexane when it turns up and i have tried it out. It is safer than n-Hexane and according to Benzyme "the inter/intramecular forces are the same.. 100% Van Der Waals." So i am hoping that the UK will have a good selection of solvents to choose from very soon.

If you have a hard time finding out what is behind a specific EINECS number for many hydrocarbons, from p10 to p16 is a nice list:
