this review title is: not gentle enough contains baking soda but written as sodium bicarbonate and the content is: this deodorant is not for the most sensitive of skin when i read the ingredient list i did not see baking soda so i went ahead and bought it i used the deodorant for a couple of weeks and thought this stuff works all day then my armpits turned deep cranberry and the skin cracked and peeled like a sunburned nose i really wish they had labeled this deodorant as containing baking soda instead of using some fancy term for baking soda and they could have saved me from a week of pain and being cranky with the world because my armpits feel like they are raw and on fire if you can use natice or schmidts this stuff is better consistency smell and longevity but if you are allergic to baking soda steer clear.there are other information for this review, one is this reviewer did purchase it and the other is 2 people think this review is helpful.
