I stopped using deodorant/anti-perspirant about four years ago, because I was tired of all the chemicals. I remember writing a speech in college about the aluminum in anti-perspirant being linked to Alzheimer's, and it got me researching that topic quite a bit. Plus, deodorant/anti-perspirant never worked very well for me at keeping the stink and sweat at bay, no matter what I tried.
Then I moved on to the deodorants at the health food store that supposedly had fewer chemicals in them, but was never real happy with how they worked. And I still didn't know what all the ingredients were!
Finally I decided to make my own. I wish I had taken the plunge YEARS ago! Since I'm really into DIY stuff, I found this recipe at the Naturally Knocked Up blog. It uses only four ingredients: coconut oil, cornstarch (or arrowroot powder), aluminum free baking soda, and tea tree oil (or another kind of essential oil, but the tea tree oil is used for its anti-bacterial properties, and helps with any smell issues you may have). Keep your old deodorant containers to put your homemade deodorant in. I need to have three old containers to have enough space to put this recipe in!
I use coconut oil a lot (we buy it in bulk and wait for specials to get a good price from Tropical Traditions... if you buy small amounts at your grocery store, it can be pretty spendy) so I always have it on hand. I don't recommend substituting another kind of oil. Coconut oil is very high in saturated fat, so it is in the solid state up till 75 degrees F. when it starts to melt. So you may need to keep this in the fridge if you are somewhere that gets warmer than that.
Make sure you read the tips listed on the above link for using the deodorant. One tip is letting the deodorant soften with the warmth of your skin before you smooth it on. It doesn't rub on right away like your typical deodorant. I find myself sort of dabbing it on.
Also, I like how the blog's author talks about this deodorant allowing the body to work the way God intended it to. Sweating is a way to remove toxins from the body, and when you block the toxins from coming out, that means they move somewhere else in the body. Ick. Personally, I'd rather let the toxins come out, rather than letting them hang around.
Both my husband and I have been using this first batch of deodorant exclusively for three months, and I only now had to make a new batch. We both love it! We're normally pretty sweaty people, but when using this deodorant, even when it's been hot out, we've had great success.
If you're looking for a different deodorant, give this recipe a try!
