Speaking of removing makeup with oil, see this from "thebeautybrains".
There is even a blurb on emu oil.. he he! -Artist

"Like dissolves like
When you use oil to remove oily dirt you're employing the chemical
principle called "like dissolves like."; In other words, oils will
dissolve other materials that have a similar chemical structure. As an
example let's look at emu oil just because the emu is a silly looking
bird and it always makes us smile. The atoms in emu oil (the solvent)
are held together by covalent bonds. Now, if the solute is greasy
makeup or skin oils (aka sebum), it also consists of atoms that are
hooked together with covalent bonds. So that means that emu oil is
similar enough to dissolve all the gunk on your face. Cool, huh? What?
