Combine coconut oil, shea (or other) butter, and beeswax in a double boiler, or a glass bowl over a smaller saucepan with 1 inch of water in it. Combine in a quart size glass mason jar with a lid instead and place this in a small saucepan of water until melted. This will save your bowl and you can just designate this jar for these types of projects and not even need to wash it out…
Turn the burner on and bring the water to a low boil. Stir ingredients occasionally until they're melted and smooth.
Remove from heat and add the vitamin E oil, baking soda, arrowroot powder, probiotics, and essential oils. Make sure the mixture is not hot to the touch (warm is ok) so that the heat doesn’t kill the probiotics. If you're using the brand I've linked above, they're fine at higher temperatures.
Gently stir by hand until all ingredients are incorporated.
Let cool for about 15 minutes, until the mixture is slightly thickened, but still a pourable consistency.
Pour the deodorant mixture into new or repurposed and cleaned deodorant containers. Let dry overnight to fully harden.
Notes
This recipe can be adjusted to make any quantity that you’d like by increasing the amount of ingredients used.
Shea butter yields a softer deodorant consistency, while cocoa butter is much firmer. You can also use a blend of shea butter, mango butter, and/or cocoa butter.
