EO is used to keep plastic soft during the molding process, not to mention other chemical applications.
I have seen it, and used it. My body does not like it but had few small issues. Allergy I think.
I have also herd lots of people with bad allergic reactions to it.
Try it out, if its not for you its not for you.
But its so smooth it will go through a 31.
You may also pay a premium for it.
