This deodorant contains no aluminum chlorohydrate, aluminum zirconium, parabens, or phthlates. It is made of natural mineral salts, and it really works to keep odor at bay. I have tried a couple other roll-on mineral salt deodorant, and this is the only one that keeps the stink away even through a vigorous workout. I love this stuff - it works without that "fragrance" scent that comes in many conventional deodorants, and there's no itchy feeling that sometimes accompanies natural deodorants.
I use the original, unscented version. It retails for $3.99 at Walgreens. One deodorant lasts about 6 months.
