I've had problems using scented stuff to the point where my face will burn like fire if I use something with a scent in it. Even the very mild fragrance in MWF (and check the label, it's there!) left me hurting. Throughout the experience of trying several scented offerings that were awesome (even moisturizing despite their painful nature), I tried one mostly unscented offering that has been my one and only friend, and a friend for life.
Try some VDH glycerin. It's cheap, it's effective, and frankly the scent is so weak unless SWMBO were to try inhaling the puck, you should be okay. By the time you whip it into lather the scent is pretty much gone (though I guess a lather fight might be out of the question...). For 1.27 a puck on Amazon (though probably 2-2.50 for a trial puck in the store) it's worth a try.
My name is Chris but you can call me "subtle as a train wreck."
