it's a medical grade solvent. it penetrates skin like smoke through a fan. you can mix lemon juice in it, rub it on your cheek, and you taste the lemon juice instantly in your mouth.
the only thing you have to be careful about is making sure the area you prepare in and the containers you use are very clean. if you get anything in it, it'll be in you, too
they use it in a lot of stuff like mentholatum rub, pretty safe as long as you don't contaminate it. it has industrial uses, so make sure you get medical grade. i don't think the industrial would hurt you, but they put something in it that makes it stink like garlic
