6-8 Tbsp Coconut oil (solid state)
1/4 cup baking soda
1/4 cup arrowroot powder or cornstarch (arrowroot is preferred)
Combine equal portions of baking soda & arrowroot powder.
Slowly add coconut oil and work it in with a spoon or hand blender until it maintains a firm but pliable texture. It should be about the same texture as commercial deodorant, solid but able to be applied easily. If it is too wet, add further arrowroot powder/cornstarch to thicken.
You can either scoop this recipe into your old deodorant dispensers or place in a small container with lid and apply with fingers with each use. Makes about 1 cup. This recipe lasts about 3 months for two people with regular daily use.
