Does deodorant cause breast cancer or other diseases?
If you've ever read about the potential health impacts of deodorant and antiperspirant (the two are in fact different, as only the latter actually blocks sweat, the former just masks smell), you might feel quite alarmed by the supposed risks. A quick Google can tell you that your deodorant will give you breast cancer, Alzheimer's, kidney disease, and other frightening illnesses. But are these claims backed up by science?
Peer-reviewed, scientific sources tell us that in the case of breast cancer, Alzheimer's and kidney disease alike, even conventional deodorant use is likely not linked to the development of these diseases or that results are inconclusive. It is recognised that further research is needed in the area – so there's nothing stopping you from erring on the side of caution – but that with the studies done up until today, no clear, causal link is found.
What ingredients should you avoid in your deodorant?
If you want to avoid the ingredients in question here, they are aluminum and parabens. Aluminum is the active ingredient in antiperspirants, as they create a temporary 'plug,' which stops the flow of sweat from sweat ducts to the surface of your skin. Frequent application of aluminum-based products to the armpit, which is close to the breast, can lead to absorption into the skin. This absorption may have hormonal effects that contribute to the growth of breast cancer cells. So the logic around potential links between aluminum and other diseases is the same – absorption is the risk. There is also some fear that temporarily blocking the ability to sweat means temporarily losing the ability to release toxins – but lymph nodes, which are not connected to sweat glands, are responsible for this.
Similar concerns relate to parabens, which do have weak estrogen-like properties. But, again, there is no conclusive evidence that aluminum or parabens at the levels they exist in deodorant causes these diseases. Some people are concerned, though, that it is the build-up of aluminum and parabens across their skincare regime and diet that creates risk. This is particularly relevant for parabens, which manufacturers widely use in cosmetics, food, shampoo, and skincare products. If you're concerned about them, you can avoid these ingredients when you see them listed on deodorants and other products.
Is all deodorant vegan and cruelty-free?
When we talk about the deodorant that is best for us and the planet, we need to consider the other living beings here with us. Many deodorants are still tested on animals. Animal testing of deodorant isn’t simply putting some roll-on in the underarm of a rabbit, but smearing the ingredients and chemicals used in deodorants onto their shaved bare skin, and into their eyes.
Perhaps the most upsetting form of animal testing is the acute oral toxicity test, where rats are forced to swallow a substance until they become incredibly sick and ultimately die. The purpose of this test is to see how long it takes for half of the exposed animals to die within 14 days of swallowing the substance. Unfortunately, this is all too common in the personal hygiene and cosmetics industry.
What’s more, not all deodorant is vegan. Some deodorant contains gelatin – made from boiled animal skin, tendons and bones, while others may contain beeswax, animal-derived glycerine made of animal fat (vegan glycerine from vegetable oil fortunately exists too), and other unappealing and cruel ingredients.
For those wanting to avoid supporting all of the above mentioned cruelty to animals, there are a huge range of vegan and animal-testing free certified deodorants available.
How does deodorant packaging impact the planet?
It’s estimated that 120 billion units of cosmetic packaging is produced every year. Unfortunately, a large amount of this packaging is not able to be recycled, ending up in landfill, or if not properly disposed of, the ocean.
The health of the planet and our personal health are completely intertwined. While personal hygiene, skincare and makeup companies must take responsibility for the impact of their products and use more sustainable and even reusable packaging, we have a part to play, too.
Today, there are deodorant brands that sell refillable roll-ons, which use glass packaging that is more valuable in recycling systems, and even compostable packaging. These are great options to choose.
For a topic as simple as deodorant, a lot of concerning points have been raised here! Luckily, it’s not so hard to avoid all of these concerns, while staying fresh as a daisy. Here are some of our favourite natural, aluminium and paraben free, vegan, animal-testing free, and sustainably packaged deodorants – they sure tick a lot of boxes!
