I like to melt my Van Der Hagen Deluxe soap and add a fragrance. I've been adding Bay Rum aftershave, but that's usually over half alcohol and it has occurred to me that I would do better to find the ingredient that is just the bay rum fragrance, without the other things that make for a good aftershave.

What should I be looking for to add the bay rum fragrance to my soap without adding all that alcohol and other stuff?

Am I just barking up the wrong tree here?
