Sustainable deodorant: why you'll want to switch today
This article is from Soul Stores.
Most people use a deodorant every day. But many deodorants contain substances that can be harmful to your body and the environment. How dangerous is it really? And can it be done differently?
Most people use a deodorant every day. But many deodorants contain substances that can be harmful to your body and the environment. How dangerous is it really? And can it be done differently?
Opinions differ
Opinions on the harmfulness of deodorant or anti-transparent to health are divided: Some say that the amount of dangerous substances is so small that they can hardly harm your body. Others claim that the active ingredient used in most common deo or antiperspirant can even be carcinogenic. We are talking about the ingredient aluminium chlorohydrate, popularly called aluminium salt. There is still much uncertainty about its long-term health effects, but one thing is certain: as we say in Dutch, it has a smell to it.

Aluminium in your deo
It is and remains a hot topic: aluminium in deodorants and antiperspirants. Because: what does it actually do there? The ingredient aluminium chlorohydrate acts like a stopper on your sweat glands, temporarily stopping you from sweating in the areas where you applied the product. The skin stays dry, giving unwanted odours no chance. That seems like good news, but how healthy is it to block your sweat glands day in and day out? There are dermatological studies showing that this is not necessarily bad for your health. After all, the area of skin under your armpit involves only 1% of your total skin surface area and sweat can find its way out through other sweat glands (ever had a wet lower back?).
Aluminium in your body
Except that a study by the RIVM and the Norwegian VKM, suggests that daily exposure of aluminium on your skin, may lead to absorption of that substance and therefore may indeed be harmful in the long term. Or - to quote the RIVM: "After absorption, aluminium distributes to all tissues, and is able to accumulate in some tissues, such as bone tissue. Elimination from some tissues is slow so that, after cessation of exposure, the aluminium may remain present in the human body for a long time."
Possible consequences
Aluminium is known to have epigenetic effects, irreversible changes in gene functions. In addition, the substance can cause DNA changes and may be endocrine disrupting. Not surprisingly, aluminium is being scientifically researched worldwide as a possible cause of reduced fertility and even breast cancer. If on the latter, opinions are divided. For instance, one breast cancer study says there is a link between aluminium in breast cells and faster tumour formation. But the KWF refutes this. If you are systematically exposed to aluminium for a long time, through intake of food, water and use of cosmetics, it can be harmful to your health. But research is still in its infancy, and the long-term effects are still unknown. Until then, however, I would rather be safe than sorry.

Natural deodorant: spray, spread or roll?
That spray- or roll-on deodorants are not exactly the most sustainable cosmetics product ever will come as no surprise. Although nowadays, the propellants released by spray cans do not affect the ozone layer like the CFCs of yesteryear. And aluminium packaging is increasingly being recycled. Most standard deo rollers are sold in plastic packaging and contain a large amount of microplastics. As a result, they have been contributing to that ever-growing plastic soup in our oceans for years. On the handy app Beat the Microbead, you can see exactly which products in your bathroom cabinet contain microplastics.
Sustainable deodorant: cruelty-free too?
Although many brands claim to be 'cruelty-free' these days, it is good to remain critical. Animal-free and vegan have become popular marketing terms and, unfortunately, there are cosmetics brands that misuse this. Want to know if your products are vegan and/or animal-tested free? Then take a look at the Dutch animal-free cosmetics list published by website Shop Like You Give a Damn. This guest blog was written by Talita Kalloe.
