Storing bulk oil for "travel"

I've got a buddy who is going on a very long trip to new Zealand, he needs to take provisions with him 200ml of test I'm going to brew it for him but we need a inconspicuous container. He is insistent on a hair oil bottle my concern is its made from plastic, will this be okay or will the bb melt the bottle?

BB will eat through plastic eventually, but it depends on the concentration as well

Whatever you do be very careful, New Zealand has some of the toughest customs and laws on the planet. Proceed with caution.

I’d take that advice very serious considering the source!!
