I've never tried it, but don't want to. With my career in the natural health field, I'm amazed how many people have severe allergies but don't mention it until they have to. I mean... how many people expect a soap to trigger a deadly peanut allergy? One of my massage clients likes peanut oil during her session, but I keep it in a clearly labled bottle, away from the other oils. Just in case someone saw no reason to mention his/her allergy.
