Ingredients: Organic arrowroot powder, organic coconut oil, aluminum-free baking soda, organic spearmint essential oil, organic tea tree essential oil. USDA Certified Organic Description: With refreshing spearmint and earthy, calming tea tree, this 'Pit Putty is hugely popular and effective. Not only do you get the arrowroot powder to help absorb the sweat and powerful essential oils to deodorize, but you get the power of baking soda. Baking soda is a natural odor-blocker and also raises the pH of the underarm so it's less hospitable to odor-causing bacteria, but because of the overall silky-smooth texture and low concentration of baking soda used, it's appropriate for all skin types -- even rash-prone skin.
