I recently used Tom's of Maine deodorant and received the worst chemical burn of my life.The ingredient which I believe caused the burn is called propylene glycol. Propylene glycol is a chemical usd to make antifreeze and is highly toxic. So when I called Tom's of Maine the recording said at the end ''If this is a medical emergency please dial...'' this only confirms to me that they have had medical issues with their products, hence I will never purchase from them again. Many others have stated the exact same issues that I have and nearly all of them attribute their burn to the propylene glycol.
