I use spiced rum from my local store in this. Since this is a water based witch hazel distillate with alcohol as the preservative you wouldn’t be able to make it into a lotion bar. A lotion bar is made with oils and waxes and won’t mix with anything water based, since oil and water don’t mix. You could add the essential oils used here to a lotion bar recipe, but it wouldn’t include the rum or witch hazel which is what tightens the pores and makes it an aftershave. It would be more of a bay spice scented lotion. Thanks for your question!
