Hi everyone! I am interested in making bath salts to resale and after trying many complicated recipes with bad luck , I am wondering if its a "the simpler the better" thing that works best for bath salts? I am considering using just Dentritic salt, dead sea salt, and essential oil instead of all the glycerine, baking soda and the like. What are your thoughts? Like everyone I want a product that does not clump and maintains its scent. My previous batches seemed great at first but faded fast after a weeks time. I thank you for your input!
