Ensure that the deodorant container and utensils you will be using for this DIY project are thoroughly cleaned and sanitized.
In a small saucepan, pour some water and place it on the stove over low heat. Put a heat-resistant bowl, I have a glass bowl I only use for making deodorant or soap, on top of the saucepan.
Add 2 tbsp of coconut oil, and 2 tbsp of shea butter, to the heat-resistant bowl. Let them melt slowly until they form a smooth liquid consistency.
Once the coconut oil and shea butter have melted, add 4 to 5 tbps of arowroot powder to the bowl. If you prefer, you can use cornstarch instead of arrowroot powder. Stir the mixture thoroughly until all the ingredients are well combined.
Carefully transfer the liquid deodorant mixture into the clean containers. For convenience, you can use an empty deodorant stick, a small glass jar (brown glass), or even repurposed lip balm tubes. Allow the deodorant to cool and solidify completely before use. I like to put it in the fridge overnight so it will cool down fast.
