If you enjoy making natural deodorants, body powders, or unique cosmetics, use arrowroot powder to add unique properties to your creations. Arrow root powder is a white, silky powder that provides a better glide in deodorants and is used as a natural alternative to talc in body powders. It's also used in cosmetics as a thickener, but unlike most thickeners, arrowroot is able to thicken at room temperature, and at varying pH levels.
