| The arrowroot powder can be used all by itself as a soothing body/bath powder, just add scent to suit your nose.
The above quantities are provided as a guideline. Basically, you want to use equal parts of baking soda and cornstarch, adding about 20 drops of fragrance oil for each cup of the mixture. Combine dry ingredients in a bowl and mix together until thoroughly blended. If you're making large batches,
you might want to cover your nose/mouth so you don't breath in too much of the powder. Then, if desired, add fragrance oil and stir until thoroughly blended.
If you're using cornstarch, you'll probably want to sift it through a screen, to break up clumps and fluff it up. Push the mixture of oil/cornstarch through the screen and mix with the rest of the cornstarch powder. You may need to repeat the filtering process a few times.
Let the whole mixture sit in a sealed jar overnight. This allows the scent to permeate the whole batch. Be sure to let dry before packaging.
