After alternating for the last few years between Ban Roll-On (for days I know are going to be stinky and stressful) and The Rock, I've finally succumbed to the allure of homemade deodorant. There are quite a few recipes online for making your own.
Some people use straight up baking soda and have found that it's a little irritating, so they cut it with cornstarch. Other people have found success by mixing equal amounts of baking soda, cornstarch and coconut oil to make it into more like a deodorant bar.
I liked the recipe I saw on Angry Chicken (us chickens have to stick together), except I didn't have shea butter so I fiddled around a bit with the recipe to make a deodorant bar that is more like what you get from the store.
Here's what I ended up using:
2 T coconut oil
1.5 T cocoa butter
2 T baking soda
2 T corn starch
Sandalwood essential oil
Let me first point out that most sandalwood essential oil isn't sustainable. But, the stuff I have is really old and it gives the deodorant a nice hippie feel to it. Sandalwood is supposed to be antimicrobial, for whatever that is worth, so if you have some use it, but don't go out of your way to get it. The cocoa butter kind of overpowers any smell in there, so if you don't like that make sure you buy deodorized cocoa butter if the smell is too strong.
Anyway, I melted the oils in the microwave, added in the dry ingredients, mixed well and added in the essential oil. You can pour the cooled, but still liquid deodorant into a 2.5 oz deodorant plastic applicator for easy application and put in the fridge to harden. Make sure the applicator is the kind with the "screw" in the middle of it. If you don't have an old applicator, you can pour it into a small wide mouth canning jar or other small lidded container and put it in the fridge to solidify.

I know what you all are wondering: sure it looks easy enough to make, but does it work? Well, I've used this on the day I got my legs sugared at the local beauty academy (totally worth the $10, but man they sucked) and came out smelling okay in spite of the profuse sweating going on in there.
I also used this deodorant when I got my nose pierced the other day which was, needless to say, quite nerve-wracking and lo and behold, no stink! So, if I can make it through those sorts of events that would normally require a Ban Roll-On kind of day, then I'm sure it will work fine on your average day's stress and sweating.
