I've tried several natural deodorants and they were ok. But this one, is probably one of the best I've ever used. I believe you will feel the same. THERE ARE NO aluminums, parabens, phthalates, triclosan, propylene or glycol. All these ingredients are known to cause Alzheimers. 
Ingredients are:
Caprylic/Capric Triglyceride, Beeswax, Cetearyl Alcohol, Zinc Ricinoleate, Magnesium Hydroxide, and corn starch.
