Homestead Series - How to Make Deodorant

Warning for Homemade Deodorants in General: I asked a chemist friend of mine, who is a pharmacists, about what do if you get redness, rashing, or darking of skin ...and he said this: "If necessary the person needs to adjust the amount of baking soda and alter that pH level. Cut down the amount of the baking soda to less than 20% and use arrowroot powder or cut out the cornstarch and replace with the arrowroot powder until you get a homemade deodorant that works for your PH type.
Stop using if you see a redness, rash or other cracking or darkening of skin immediately until you rectify the PH level of your homemade cosmetics.
If you introduce liquids to your formula, be sure to add a broad spectrum preservative as well as this can cause an infection down the road as well. Wash out containers and sterilize each time you refill them. I hope this helps. I certainly have not heard anyone else have this issue... but I do know that some ppl have turned to arrowroot flour to get their best results. Work with it until you get what you like.
I also added 1/4 tsp. Vitamin 'E' oil to the mix-- and this last time, added about 1tbsp mango butter. Also used lime, coconut, vanilla, and butter extract for an awesome Coconut Lime Twist Scent! Loved these changes! This keeps me dry; no wet underarms! No odor! Washes out on my white T-shirts and doesn't stain my good clothes. It goes on fairly clear. I'm in construction during the hottest part of summer...and I'm menopausal...and it works for me for only .50 cents per 4 sticks!
