I made my own deodorant for the first time last night and I am NEVER buying it from the store again. Not only was it quick and easy, but it smells better than the overpriced storebought junk AND it contains zero aluminum or SLS (yippee!!!).
I got the recipe from Craftster.org, and it's so simple it's almost silly. The person that posted the recipe (GirlOnBike) got a lot of responses and thank-yous for letting us know how easy it is to create your own deodorant :)
(Please note, however, that it's not an antiperspirant. If you sweat a lot you might find that the homemade stuff doesn't do the trick.)
Here is the recipe and instructions:
1/4 cup baking soda
1/3 cup cornstarch
10 drops of your fav scented oil (make sure it is the type you can put on your skin!!! Tea tree oil is also a good bet, because of its antibacterial properties, but I can't use it because I am allergic, so I just used marjoram and rosemary scented oils.)
1 tbsp + Coconut oil*
*I changed the recipe and used almond oil, simply because I had that lying around the house. Next time I would try with coconut oil, however, because mine didn't set the same way it was described in the original post.
GirlOnBike's instructions were to mix together in the order listed, adding enough coconut oil to give your deodorant the consistency you like. With the almond oil, I had to add about 4 tablespoons, which leads me to believe it isn't as useful as coconut oil in this recipe. I've heard the same comment about canola oil, which some of the other people on the forum had tried.
Then, she suggests putting it in the oven or dehydrator at 150 degrees Celsius for about 15 minutes to allow the cornstarch to thicken. You can either mush it into an old deodorant container (no, it won't melt at that temp) or just mush it into a block. It is supposed to get "gooey" in the oven, and you are supposed to let it cool before touching it, but mine didn't do that. I believe, again, that it was due to my choice of oil.
However, even though I don't think my results were quite as "professional looking" as the original version, I used the deodorant this morning and it worked just fine! I ended up putting it into an old container which is probably why it still worked, despite the fact that it didn't thicken properly. If you are doing it without putting it in a proper deodorant dispenser, however, I would highly recommend using coconut oil and following the steps outlined above exactly.
I've been using it for about two weeks now and I am never going back to putting expensive, cancer causing deodorant on my armpits again. HOMEMADE FTW!
