I saw this recipe for homemade deodorant from Passionate Homemaking, and I read the comments which had people raving about it. So I mixed some up.
5-6 Tbsp Coconut oil
1/4 cup baking soda
1/4 cup arrowroot powder or cornstarch ( I used cornstarch)
Combine equal portions of baking soda & arrowroot powder (or cornstarch). Then slowly add coconut oil and work it in with a spoon until it maintains the substance you desire. It should be about the same texture as the store bought kind, solid but able to be applied easily. You can either scoop this into your old dispensers or place in a small container with lid and apply with fingers with each use. After applying the product, you can just rub the remains into your hands as a lotion! This recipe lasts about 3 months for two people with regular daily use.
Here's the deal. You will still perspire. You will. But that's healthy...it's what we're meant to do. But, I've had great results in keeping the smellies at bay. Apparently coconut oil is a natural antibacterial. Mix it with the baking soda and corn starch and it's a miracle!
The website where I found it says you can mix it up to the consistency of regular deodorant and pack it down into an old dispenser. I don't recommend this! If it gets a little warm (say 80*), it liquifies. Still usable, but liquid. Keep it in a little container with a lid, apply it with your fingers.
I can confidently throw away my carcinogenic, metal laden, store bought deodorant....I'm hooked on this stuff!
