I’ve been trying homemade deodorants. Coconut oil + bicarb worked ok most days but some of my tops got grease stains. Coconut oil+ magnesium hydroxide didn’t seem as effective and the grease problem persisted. Third experiment was with rose water and mag. hydroxide. Only tried it for three days yet, but it seems to work ok. Questions: 1) anyone else tried this? 2) is there a meaningful difference between cosmetic rosewater and the cooking stuff? The one I have now is meant for cooking, are the expensive flower waters from essential oil companies more concentrated or something? 3) what preservative would you suggest for this? I have it in a pump bottle now and apply with my hands, but mean to get a roll-on bottle if my experiment is successful. So a lot of contact with skin + I would like to be able to make 2-3 bottles at a time, it needs a decent shelf life. Alright, this experiment is moving on! The flower water+magnesium does not do it for me. My next candidate is a recipe from Mommypotamus. It’s a stick with butters, beeswax, magnesium and kaolin clay.
