We broke a bottle of Eucalyptus Essential Oil recently. The closest thing to salvage the oil was a sandwich bag, so we dumped it in there. I meant to transfer it to glass right away but the day got away from me & so before bed I set the whole bag in a styrofoam cup. I was assuming the EO would melt the bag & figured that putting it in the cup would at least keep the mess off the counter.
In the morning, the EO was still in the plastic bag! It didn't eat through the bag! I was shocked! BUT... it somehow ate a hole in the styrofoam cup!?!?!
An hour later, at 8:14, the cup I poured EO directly already has a hole... a large part of it has already "melted" onto the counter. The first time there was no residue remaining. It's a much more dramatic reaction & much faster. Thus, I am certain no EO was on the outside of the bag the first time. The 2nd cup (with EO contained in a bag like the 1st time) seems to have started to become tacky... but it's too early to really tell.
What I want to know is... HOW and WHY did the EO eat through the styrofoam cup but not the bag? Is the plastic bag porus? I'm so curious!?!
I did the same "experiment" with nail polish remover replacing the EO... but I used "non acetone" nail polish remover & I think I was supposed to be testing for the effects of acetone. Oops. I'll scrounge up some of the type with acetone and repeat & post. There were NO noticeable effects w/the non-acetone nail polish remover to the bag or cup.
