Melt the shea butter, cacao butter, and coconut oil in a medium saucepan on a double boiler. Remove from the heat and add essential oils, mixing them in. Gradually add the baking soda and arrowroot powder, mixing to incorporate as you go.
Spoon the mixture between prepared, clean jars with a lid. Let the deodorant sit for the arrowroot and baking soda to fully absorb all the oils, about 24 hours. During this time, the mixture will transform from thick and creamy to a more hardened paste. Keep the jars that are not in use refrigerated.
To apply, use a small wooden stick or a tiny spoon to scoop out a small amount of the deodorant. Rub between your fingers to melt and gently apply to your armpits, making sure to fully cover the area.
