Ever hear of something called "Aluminum"? It's a metal, for thoughs who don't know. Well, you can find this "metal" in your deodorant. You may be saying "Okay, So?"...
Aluminum is a metal the skin can absorb when in liquid form. Your body is not able to break it down so it stores it in pockets of the tissue. Prolonged use will form tissue clots, or, TUMORS. These tumors can be VERY cancerous. Its one of the leading causes of breast cancer in women.
Another ingredient found in most deodorants is Propylene glycol. This is known as "Antifreeze" to most automotive users. Yes.. Antifreeze is goes on your SKIN with every application. Sadly, it is also found in paint, floor wax and even... Dog food. Propylene glycol is neuro-toxin known to cause contact dermatitis, kidney damage, and liver damage.
FD&C colors are made from coal and have been shown to cause cancer in animals; they also often cause allergic skin reactions. Triclosan can be absorbed through the skin and causes liver damage in some lab animals, and quaternium compounds are the number one cause of preservative-related contact dermatitis. About 5% of the population is extremely allergic to quaternium compounds, which can cause asthma-like symptoms and even respiratory arrest when inhaled. This, is ALSO in your deodarant.
I can name a few other chemicals that cause problems but I'll leave that to you to do some research.
I'd advise people to stop using it and stop buying it. I have a solution that is not only healthy and safe but even more sanitary then that junk in tube. Its baking soda and peroxide! I have tested this myself today, actually and it works WAY better. I didn't shower, worked out and waited hours. I stunk pretty bad. I took some baking soda and mixed in peroxide until it was a watery substance. I then poured it onto my hand and rubbed my arm pits. Spell vanished INSTANTLY. The reason why? It is bacteria that causes this odor. When you apply baking soda is covers the smell, when you apply peroxide, it kills the bacteria = NO SMELL!
I hope everyone who reads this makes the switch.
NOTE: Not all baking soda is created equally. Some have aluminum in them! I use Arm and Hammer as it only has one ingredient.
