Volcanic Minerals?


Hi Stephanie,

The new body shop deodorant "DeoDry" claims to use "volcanic minerals" to absorb & evaporate sweat, keeping you dry. Despite it being aluminum & paraben free, it contains a host of harmful chemicals. For this reasom I would never use it, I'm just wondering if this whole volcanic minerals thing is for real? How would it stop you from sweating? Is it safe?

Thanks! Ama L.

Thanks for your question, Ama!  It looks like the "volcanic minerals" they're talking about is perlite. It's kind of an iron-based clay that doesn't really pose a risk as-used. (Perhaps if you inhaled the dust, but that's not an issue with this product.) It will work to an extent to absorb moisture, but it's not going to keep you from sweating.  (This product is considered a deodorant, not an anti-perspirant.)  Just for kicks, let's take a look at what else is in this deodorant:
Propylene Glycol, Water, Glycerin, Stearic Acid, Hamamelis Virginiana (Witch Hazel) Water, Ceteth-20, Perlite, PEG-40 Hydrogenated Castor Oil, Sodium Hydroxide, Fragrance, Alcohol, Hexyl Cinnamal, Aloe Barbadensis Leaf Juice, Limonene, Eucalyptus Radiata Leaf Oil, Thymus Vulgaris (Thyme) Flower/Leaf Oil, Citral, Citrus Nobilis (Mandarin Orange) Peel Oil, Cymbopogon Flexuosus Oil, Rosmarinus Officinalis (Rosemary) Oil, Citrus Medica Limonum (Lemon) Peel Oil, Linalool, Eugenol, Eugenia Caryophyllus (Clove) Bud Oil, Satureia Montana Oil, Geraniol.
Propylene Glycol is the first ingredient here.  Propylene glycol is an irritant, penetration enhancer, and suspected neutrotoxin. (Read more here.)


Ceteth-20 and PEG-40 Hydrogenated Castor Oil are both ethoxylated chemicals. This means they've been created using the carcinogen ethylene oxide, traces of which can remain in the product, along with its carcinogenic by-product 1,4-dioxane. 

"Fragrance" is a blanket term for anything on a list of over 2000 different chemicals, including neurotoxins, endocrine-disrupting phthalates, allergens and more. (Read more Here.)

So, despite it not containing aluminum, it looks like this product has quite a few problematic ingredients not just at the end of the list, but that comprise the bulk of the formula!

I love your website and how you explain the real truth about chemicals. Great job!

I have a related question. Is adama clay dry deodorant safe? EWG says there is fragrance, but zion healths website lists the fragrance and it seems ok. Also there are 8 different kinds on the zion website, are any of the 8 ok?

Thanks for your question, Joy. They list it as "natural pine fragrance" so it's hard to this a pine essential oil or what? I would contact the company and ask exactly where this "natural pine fragrance" comes from.

But, in addition to that question, it does look like it contains Grapefruit Seed Extract, which is one of my chemicals I suggest avoiding. It sounds like a natural extract, but it's actually a synthetic chemical. Check out the article here
