Strong claims have been made regarding the safety of aluminium in deodorant. However, as with so many headlines, stories can get blown out of proportion or simply altered over time. Let’s find out the truth…

The Claims That Have Been Made.

Aluminium causes breast cancer.

It is said that because aluminium in deodorant stop toxins being expelled through our skin, that the toxins are instead clogging up our lymph nodes around our armpits and breasts. This is then what is said to cause breast cancer.

It is also thought that the risk of this is higher for women who shave under their armpits before applying deodorant as the aluminium is absorbed into the skin quicker through any nicks from the razor.

Also, it has been said that for women, the aluminium in deodorant could interact with DNA. This could then lead to cancerous changes in cells or even interfere with estrogen, which is already known to influence the growth of breast cancer cells.

Aluminium in deodorant causes Alzheimer’s

As Aluminium is absorbed by the skin, it is said that it then affects the blood brain barrier which is then linked to the onset of Alzheimer’s.

So yeah, pretty strong and ugly claims!

The Truth about Aluminium in Deodorant. Strong claims have been made regarding the safety of aluminium in deodorant. However, as with so many headlines, stories can get blown out of proportion or simply altered over time. Let’s find out the truth…

Breast Cancer.

First, it’s worth noting that most of the research that looks into the link between breast cancer and aluminium in deodorant comes from only one research group.

According to Ted S. Gansler, MD, MBA, director of Medical Content for the American Cancer Society, “There is no convincing evidence that antiperspirant or deodorant increases cancer risk”.

There was a study published in 2002 by the Journal of the National Cancer Institute that looked into the relationship between breast cancers and deodorants in 1606 woman. The findings did not show an increased risk of cancer among the deodorant.

One of the Myths mentioned above states that ‘aluminium stops toxins being expelled through our skin and the toxins are instead clogging up our lymph nodes around our armpits and breasts.’  Actually, antiperspirants block sweat glands, not lymph nodes. Also, breast cancer actually starts in the breast and then spreads to the lymph nodes, not the other way around.

The Cancer Council states that “Reputable organisations like the American National Cancer Institute, cancer research UK, the American Cancer Society and most other major authorities suggest a link between deodorant or antiperspirant use and breast cancer is unconfirmed, or simply a myth.”


Heather M Snyder, PhD, Senior associate director of Medical and Scientific relations of the Alzheimers Association says that, “There was a lot of research that looked at the link between Alzheimers and aluminium, and there hasn’t been any definitive evidence to suggest there is a link.

According to, “At present so little is known about the underlying cell changes in Alzheimer’s disease that the definitive statements about the role of aluminium cannot be made with any certainty. However, the balance of evidence does not appear to support a specific role for aluminium in Alzheimer’s disease”.

The Cancer Council make a great point on this when they say, “Studies show that there is no relationship between antiperspirant use and Alzheimer’s disease. Humans are exposed to aluminium from food, packaging,  pans, water, air and medicines. From the aluminium we are exposed to, only minute amounts are absorbed, and these are usually excreted or harmlessly stored in the bone.”


Sweating is natural, we need  to sweat as it’s our bodies natural way of cooling down and removing toxins. Considering this, it then doesn’t seem right to block our pores preventing this natural process from happening.

The trouble is that aluminium isn’t the only toxic ingredient in deodorants.

Other toxins that can be found are:

  • Parabens
  • Steareths
  • Triclosan
  • Propylene Glycol
  • TEA & DEA
  • Artificial Colours

Dr. Mercola reports that, “A 2012 study found one or more parabens in 99% of the 160 tissue samples collected from 40 mastectomies”

From this the conclusion is that using a natural deodorant is the best way to go.

    I’ve been allergic to deodorant for years and just suffered through it. This past year I finally decided to try organic deodorant and my skin feels so much better! My only complaint is that I have to reapply several times a day to avoid stinking. This is better than suffering through all of the junk they put in it. Great post!

      I am so glad you have found something that better suits your skin! If you are having to reapply several times perhaps have a look around, there are so many varieties available!

    Thanks for laying out the facts!
    My deodorant usage has really changed over the years. One thing I noticed is that I “stink” more if I use deodorant. So, I actually only use it on days where I’m at risk of major sweating (think hot summer days or working at the office). Otherwise, I skip it.
    Second thing I notice is that if I am not drinking enough water, I will also be prone to more “smelly” sweat.

      Yes, if you find you don’t need it every day then I would definitely go without!

    I really want to use natural deodorant but I have never been satisfied with the ones I have tried. I can use them in the winter when I don’t get so hot but the minute summer rolls around I stink if I stick with a natural deodorant. Any suggestions?

      Yes, sometimes it an take a while to find one that works well for you can’t it?
      Something you could consider is an underarm detox. It is explained really well in this article: If you are in Australia then Black Chicken have a great one which you can get here: otherwise for the US I really recommend this one by Modere (I have used this myself and love it): Just remember once you apply it you then need to rub it in a little. Hope that helps 🙂

    I actually stopped using these sprays when trying to get pregnant. Annoyingly there is only one brand available n shops with no aluminum.

    Great post! Your blog has really got me thinking about the products I use. I have already been cautious about what I use for my little one, but I should be conscious of it with my products too!

      Absolutely, we have to look after ourselves too!

    Interesting read. I have an autoimmune disease and recently started to cut down on extra chemicals in my body. After tons of trial and error deodorants, along with a few homemade ones using lemon juice or baking soda, I finally found one that works. Got my entire family hooked on it and am happy to know that they will have less chemical exposure. The name is DayDry. They are located in Paris, France but just started shipping Internationally. They also started a new Facebook Page (Daydry North America) & Twitter Page in English They don’t use any of nasty chemicals. Instead it is a probiotic roll-on or spray that fights the proliferation of bacteria responsible for body odor. It does not stop you from sweating… which as you mentioned it a good thing.
    I look forward to reading more of your blog for other chemicals that I can cut down on… I’ve got a long way to go in order to truly say I am living clean.
