Menthol Crystal Cold Process Soap

Here is an interesting cold process soap from The Soap Queen called Menthol Crystal Cold Process Soap.   What is so interesting about this recipe is that the soap is scented with menthol crystals instead of essential oils.  Never heard of Menthol crystals? They happen to be a natural product that can be used in a variety of bath products including soaps, scrubs. balms and more.  According to The Soap Queen, you only need to add a few crystals to add a minty scent and cooling sensation on the skin.
