Our deodorant contains no Bicarbonate Soda also known as baking soda. Although baking soda keeps wetness and moisture at bay, it can also be very irritating to some people, sometimes to the point that it turns them off from natural deodorant entirely. According to dermatilogists, “Baking soda is highly alkaline, and often causes irritant dermatitis in armpits." As an alternative, all of our deodorants are baking soda free, that are also palm free, plastic free and plant based . And with added magnesium and charcoal to combat odor.
