Never looked into it that far but I have to believe it's better than the leading mainstream brands (secret, suave etc). No one said anything harmful about the Arm N Hammer and I have to believe Toms of Maine's products are a bit more natural than an Arm N Hammer product...I would hope at least, LOL.
Either way, I'm still comfortable with my Toms Deodorant considering it doesn't have a lot of nasty stuff in it that most deodorants do. I do so much to avoid so many harsh chems while pregnant so I have to believe all will be okay!
You're right, the Arm n Hammer is not what I would call "natural" or "safe" in any way, shape or form. Here are the ingredients in it:
Dipropylene Glycol (by-product of Propylene Glycol manufacturing)
Propylene Glycol (as discussed above)
Sodium Stearate (They make the claim that they use no animal-derived ingredients in this product, but Sodium Stearate is made up of 90% Stearic Acid which is animal fat)
Sodium Bicarbonate (Baking Soda)
Coriandrum Stavum (Coriander) Fruit Oil
Rosmarinus Officinalis (Rosemary) Leaf Oil
Lavandula Hybrida (Lavandin) Oil
Fragrance (could be a combo of any of the 200 chemicals used to make "trade secret" fragrances)
Triclosan (This was just in the news....again. Besides being one of the top 10 contaminents in our rivers and streams, it's shown to cause toxic hormonal effects and was found in the breastmilk of 60% of women tested-and has been found as a contaminent in umbilical cord blood)
Tetrasodium EDTA (A preservative made from the known carcinogen formaldehyde - this is what they use instead of parabens as a penetration enhancer - i.e straight into your bloodstream)
