I don't think EOs are meant to be taken internally...
I think Jojoba Oil is a good carrier, because it's what all the diluted oil blends at my natural food store use as a carrier. Have you tried soaking vanilla beans in oil to make your own vanilla essence? Personally, if I were making a perfume for my body, I would soak it in vodka, but you don't want to put alcohol in your hair. You could even try steeping vanilla bean and orange peel...
