Is Ammonium Alum Dangerous?

After being questioned by someone new to veganism if I used deodorant or if I was “stinky” I felt it my duty to educate the non-vegan masses about vegan deodorants as well warn those about potential risks associated with certain types of crystal deodorants.

A Note on Stinkiness

Research has shown that some people with body odour have problems in their personal and social relationships and it is no laughing matter for those with this embarrassing problem. Solving the problem of “stinkiness” will not come from antiperspirant and deodorant sprays that only mask the problem. If people find that despite regular bathing and wearing clean clothes they are still suffering from body odour they should take a good look at their diet and health in general.

Research at the Imperial College in London has shown that some people with body odour have bacteria imbalances (which can occur through use of antibiotics and steroids in particular or a diet high in fat, sugar and red meat). Caffeine and can stimulate the nervous system, which regulates sweating making you possibly sweat more. Strong spices and foods such as curry, garlic and onions is excreting through sweat and can create a strong body odour. I assume a healthy vegan diet without intoxicants is less likely to result in a body odour problem!

Please remember it isn’t necessarily sweat that creates a smell, it is the bacteria on the skin feeding on the sweat that leads to unpleasant odours. Rather than focusing on stopping sweating a long term solution addresses the bacteria through diet and deodorant.

Mineral Salt Crystal Deodorant
Dr Mercola is completely against the use of alum in deodorants and suggests limiting contact with aluminum altogether (especially in antiperspirants). In his article Aluminum Lurks in Crystal Deodorants he makes a good point that aluminum is not needed by the body and therefore it does no harm to prevent exposure. However people exposed to large amounts have been seen to develop Alzheimer’s Disease and even cancer.

So Why Does the Health Food Store sell it?

Faith in Nature was launched more than thirty years ago by Rivka with an aim to produce products from natural sources which are kind to the environment and the user too. Faith in Nature do not conduct animal testing and are on the BUAV list (Leaping Bunny Standard).  It is understandable why a consumer would trust this brand and buy a deodorant without worrying about safety issues. Faith in Nature describe their solid crystal deodorant as eliminating odour-causing bacteria and “allows perspiration without body odour”. The deodorant is vegan and has the Vegan Society logo, and is made from pure ammonium alum. Interestingly it is marketed as a natural product free from toxins.

What is Ammonium Alum?

I was not aware until recently but ammonium alum has had a lot of controversy. Faith in Nature’s Stand on Ammonium Alum After contacting Faith in Nature about their reasons for using alum I was delighted to get a reply, yet I was concerned at the quality of response:

“Our ammonium alum is a nature identical form of the natural mineral rock, We understand that it has a very good safety performance. Whilst it is not natural as such, but is a man made product. There is no waste material that goes into the crystal and all .the ingredients are of top quality, made under Good manufacturing practise.”

Eeek well spelling and grammar aside they haven’t actually answered my concern in relation to safety and their personal ethics in providing products that are both natural and completely safe for consumers.

Deodorants vs Antiperspirants

Antiperspirants are supposed to work by both constricting and blocking your sweat glands. The aluminum used in antiperspirants (not deodorants) are absorbed into your body and broken down, releasing the aluminum. The aluminum in deodorants (usually potassium or ammonium alum) lies on the skin in a thin layer and makes it alkaline stopping bacteria from growing and creating bad odours. It is likely that limited exposure to alum will not cause harm yet is it really worth the risk?

In the United States the FDA has required a new label on antiperspirants saying that people with impaired renal function (who have trouble shedding environmental toxins) and children should not use these products. Many in the industry are complaining due to lack of scientific evidence, but someone at the FDA seems to believe in “prudent avoidance”!

Is Ammonium Alum Safe?

A 2007 Daily Mail article has Dr Exley suggesting caution with natural deodorants:

“There are some non-aluminium- based antiperspirants but they don’t work as well. Myth and legend tells us aluminium is safe but reality shows us not that it isn’t safe but that we don’t know. Not knowing is not a reason for assuming safety.”

Dr Exley said manufacturers used aluminium in deodorants because it was very effective in preventing sweating.

The Vegan Alternatives

There are no peer reviewed studies as of yet that prove or disprove the safety of aluminum alum and so it pays to be cautious. I think for now I would suggest staying away from ammonium based deodorants and antiperspirants.

Safe options for vegans include Aromaco and Aromarant from Lush and High C Roll-on Deodorant from Aubrey Organics. Brace yourself for new reviews on deodorants…
