Add the arrowroot powder and baking soda to a shallow bowl. Mix, using a fork, until combined.
40 grams arrowroot or cornstarch, 1 teaspoon baking soda
Add the essential oils (in any combination you like) to the arrowroot mixture. Stir to combine.
10-15 drops essential oils
Mix in the coconut oil and shea butter, using the fork in a mashing motion. This will take a minute or so - the mixture will look too dry, but keep mixing.
