I recently stumbled across a recipe online for homemade deodorant and decided to give it a try. After some tweaking of the recipe, I am pleased with the results and don't plan on buying the store brand stuff ever again.
Here's what I did:
Girl on bikes homemade deodorant.
*1/4 cup baking soda
*1/4 cup cornstarch
*1/2 tsp tea tree, lavender, &/or your favorite scented oil
(tea tree works best because of it's antibacterial properties)
*1 tbsp+ coconut oil
Mix baking soda & cornstarch in a bowl with the oil or oil blend of your choice. Stir in coconut oil in until it’s the consistency you like. (mix it quite a bit before adding more)
Shape into disk or smash in to empty deodorant container. The cornstarch needs some heat in order to begin thickening so I put mine in the dehydrator at 145 degrees for about 15 minuets. The bar will be gooey until it cools so try to resist touching it. Once cool it will be firm and easy to handle.
