Yeah, EB is used as the solvent of choice ($) in fantastic, windex, and 409. The better choice would be it propylene derivative Dipropylene Glycol mono-methyl ether. The propylene derivative is far less toxic. EB has been shown to exibit penetration through the skin into the blood stream potentially causing liver and kidney effects, as well as blood disorders. Safe handling of EB would definitely include impervious gloves. I say this in particular that used motor oil contains dangerous free radicals accumulated from the blow by gases of of incomplete combustion. Seems natural that should protect themselves from EB providing a route of entry. The rest of the formula appears to be mainly aliphatic distillates, hydrotreated to remove any benzene ring impurities.
