Is Aluminum Chloride Safe? Myth debunked

Is Aluminum Chloride Safe?

Many questions have been asked regarding the safety of aluminum chloride. Nowadays, much effort is done to reduce chemicals in all the products that we use daily.

Organic and natural options are sought to reduce hazardous chemicals that have caused an outbreak of many diseases and have claimed the lives of uncounted individuals.

Aluminum chloride has been on the list of chemicals that may have side effects and leave a long-term negative impact on your health.  So, the burning question remains: Is aluminum chloride safe?

In this article, I am going to share what research says about aluminum chloride and how it is used in antiperspirants.

But first of all, check out a very informative video from Dr. Oz.

What Is Aluminum Chloride?

Aluminum chloride, a chemical element from the non-ductile metal group of boron, is used in rubber, to treat water, paint, among others.  It is used in the form of salts.

However, the most noticeable use for aluminum chloride is in antiperspirants. This silvery-white and soft metal form a gel-like substance that plugs the sweat glands and closes the pores of your skin temporarily.

This metal is the best-known solution for individuals suffering from hyperhidrosis. Although it gives temporary relief, it prevents sweat marks on your clothes and helps you gain back your self-confidence.

In literally every synthetic antiperspirant/deodorant you will find this chemical and you have likely used one of these at some point in your life. Maybe you are still using it.

Side Effects

Aluminum chloride has a few well-known side effects. People that have used clinical strength antiperspirants know a few of them very well.

When applied to your skin, and especially in your armpits, which are highly sensitive, it can cause tingling, mild to severe itching, skin irritation and sometimes even severe rashes.

In rare cases, research has found that trouble with breathing, swelling of tongue and throat can be traced back to the use of aluminum chloride.

However, when used as an antiperspirant, it is combined with other substances and used only in small portions so you will not have to fear any serious side effects.

If you ever experience abnormalities after using antiperspirants, do not hesitate to see your doctor.

Aluminum chloride in its pure form should never be eaten because it would burn the tissue of your inner organs and leave behind serious damage. Also, breathing this chemical can cause a series of problems, like vomiting, headaches, trouble breathing, among others. Also, avoid contact with eyes.

Whenever aluminum chloride comes in contact with moisture, it starts to have a chemical reaction, and then it starts to burn.

Therefore, when applying clinical strength antiperspirants to your armpits, palms, etc., you want to make sure that the affected area is completely dry and stays dry for at least 4 hours after application in order to prevent irritation.


When using aluminum salts, there are few precautions you need to take. First of all, if your skin becomes irritated or you get a severe rash, consult with your doctor immediately.

Also, let your doctor or pharmacist know if you have any other allergies. Other allergies you may have, can be affected.

However, these cases are very rare and I am just outlining this so you get the idea. I have used clinical strength antiperspirants for some time, and I have experienced the tingling, and mild irritation and itching, but it happened more when I left a trace of moisture before application.

If you are pregnant, consult your doctor before as well. It should only be used if necessary. If you do not have a serious sweating problem, you should clearly not use this product while pregnant.

While there is no proof that aluminum chloride goes into breast milk and no data to the moment that it can have side effects on you or your baby, it is highly advisable that you don’t apply while breastfeeding either.

Other than that, there are no specific precautions to be taken. Use as described and you are good to go.

Is Aluminum Chloride Safe?

Now to the burning question regarding the safety of aluminum chloride.

The earliest aluminum chloride therapy dates back to 1916. Over the years, many studies have been made.

I remember the email with a PowerPoint presentation that I got around 15 years ago where antiperspirants and deodorants were under examination. It said that aluminum chloride caused cancer, Alzheimer, and other diseases.

The question only remained: What should I use then for my sweating and bad odors? Back then, I had no all-natural options available and we did not know how to make something at home. So we continued to use them, against better knowledge.

The matter of the fact is that in the 1950s and 1960s, studies were done on mice and rabbits. The research concluded that cell damage was done with the application of aluminum chloride, which was a precursor to dementia and cancer.

However, these studies were never able to prove their theory. In theory, it sounded true, but no evidence was there to prove it right.

Also, through the foods that we eat, we consume more aluminum than we apply to our underarms. Food would then have to be considered a risk factor as well.

Around 15 years ago, this myth was finally debunked by the American Cancer Society and the Alzheimers Association. Studies were done on thousands of patients and not enough evidence was found that the use of aluminum chloride in antiperspirants would have been directly linked to any of these diseases.

In fact, it was found that only a 0.012% of aluminum chloride was absorbed by the body, which is such a small percentage, that the chance of building up in your body or cause cell destruction would not be able to happen.

Your skin is there to protect the inner organs of the body from dangers that can be found outside. As with other chemicals, sweating brings them out and will not let them in. That is not to state that nothing comes into your body through your skin, but your skin is there to protect you.

Therefore, not many chemicals used in antiperspirants can be absorbed by your body.

I do not suggest that you overdo these chemicals. Use them as needed only. I would never expose my body to more chemicals than clearly needed.

After extensive research is done by honorable institutions, there is not much doubt left that aluminum chloride is safe to use. Just be cautious of side effects, as described above.

How Is Aluminum Chloride Used?

One thing that sticks out is that this chemical is highly effective when treating excessive sweating. It blocks the sweat glands. In one study done by Scholes, patients were treated with 20% aluminum chloride in alcohol and all treatments were successful. All patients were completely dry in their armpits for the next few days, while others were sweating tolerably.

Today, most formulas for underarms contain between 12-15% aluminum chloride, as it has been proven to be as effective as 20%. Only that it is more tolerable because of skin irritation.

However, palmar hyperhidrosis seems to not be relieved by 15% of aluminum chloride. Only up to 30% will reduce or stop palmar sweating.

Never attempt to use palmar antiperspirants on your underarms because it could cause severe skin irritation, depending on the product used. Also, palmar sweating will not stop completely when using antiperspirants for your armpits.

Which Antiperspirants are Most Effective?

In recent years, many different and effective antiperspirants have made their way into the market. There are those that reduce moderate sweating, which is the norm for most people.  Many people should not even be using antiperspirants because they sweat so little that they would not need it.

Then there are those people that sweat moderately and need stronger antiperspirants.

And lastly, you find people like me that sweat excessively in their armpits day-in and day-out.  If you are one of those, I highly recommend using clinical strength antiperspirants like Sweatblock.  Sweatblock has changed my life completely and I was able to get my self-confidence back by applying a considerable amount of aluminum chloride once per week and my sweating is totally gone and I can enjoy wearing the clothes that I like.


Is aluminum chloride safe? On a final remark, aluminum chloride is safe and very effective in treating hyperhidrosis. If you live with hyperhidrosis, you know how embarrassing it can be, and how your social life always spins around the fact that you sweat excessively.

Having experienced it myself, I am so glad that there is a safe solution for me. I have been using it in the past years and I am extremely happy with the results. The clinical strength antiperspirants have given me back my confidence, and my social life has improved ever since.

Did I answer your questions regarding the safety of aluminum chloride? Did you know that there were studies that state there is a lack of evidence that aluminum chloride causes Alzheimer, cancer and other diseases? What do you think?

Please leave a comment below. I’d love to hear from you. Also, I invite you to share this article with friends and family. Maybe they are stressed about the deodorants and antiperspirants they use because they were misinformed. Spread the word.


Ready To Make a Change Now?

OscarHi, I have been sweating excessively for the better part of my life.  I looked for solutions for well over a decade, but I never found anything that lasted.

I had given up hope and accepted to live the rest of my life being embarrassed with ugly sweat stains in my armpits.

However, after a few years of not searching for any solutions anymore, I gave it another shot.  And I found what finally gave me the freedom I had longed for so many years. 

Now, I don’t worry about sweat stains in my armpit anymore, nor do I have to change up to 4 times daily.

My Recommendations

Recommendation #1

SweatblockA clinical strength antiperspirant is one of the first things I recommend to people that sweat excessively in their armpits because you can stop your sweating completely.

Sweatblock is a product I have used successfully for years now and it has proven effective every single time I apply it correctly.  The best I have gotten out of it are 7 days, but some people report to have been sweat-free for 10 days.

This product has saved me from many embarrassing situations!  Instead of having to hide the stains in my armpits minutes after taking a shower, I can now lift my arms as much as I want and no sweat will show.  Not one drop of sweat for many days!  

To know for how many days it will work on you, you have to try it out yourself, as it varies anywhere between 4-10 days.

Recommendation #2

thompson teeAnother thing that I always use after finding out about such a great product is a sweat proof undershirt.  I wore undershirts every single day before I found out about the Thompson Tee but they never helped.

Since I sweat so much in my armpits, I was immediately sweating through.

The Thompson Tee has a patended think sweat pad sewn nicely into the armpit.  I do not sweat through nor do I have had leaks in the past few years of wearing these.  They are so comfortable and leave me completely dry on the outside.  When I forget to put on Sweatblock, I have the Thompson Tee as a backup as I always wear one.

Could not recommend it more to anyone sweating excessively.  With a large variety of undershirts for both, men and women, you will find your perfect life-saver.

About Oscar

I am the founder and director of and have been researching and writing about hyperhidrosis for many yearOscars.

It all started when I was around 14 years of age, when I suddenly found out that I was sweating more in my armpits than I should.  At first I thought it was something that would go away soon, but I was wrong.

After finding a solution to my problem, I decided it was important to shout out my message to those that are suffering from what I had lived with so many years.

My goal is to help people find their freedom from sweating by sharing my expertise because hyperhidrosis is an underdiagnosed condition.  People don’t know that it is a medical term and can be treated effectively.

That is why I am here: Sharing with you what I know, what works and what does not work.

  1. Hi, 

    I’ve been using anti-perspirant deodorants for a long time but never gave thought to that aspect of it; I used it only to reduce bad odour.  Now I know its other use that is to prevent excessive sweating and the chemicals used in its manufacture.  It’s good to know aluminum chloride is not harmful.  Personally, I discontinued the use of any deodorant that gave me itching or other uneasiness.  But that’s a long time.  Either I’m now used to some particular brands or there are improved products on the market.  Many thanks for the info.

    1. Hi, 

      I understand your very well.  Thanks for sharing your experiences with different deodorants and antiperspirants.  Yes, the alcohol component and others can cause bad rashes.  I have lived through those as well with all the deodorants that I have tried.  

      Deodorants do not have aluminum chloride in them, because that is only to stop sweating and used in antiperspirants.  Deodorants kill bacteria that thrive on our sweat and produce the unpleasant scents.

      Personally I love natural and organic deodorants now, because they offer you protection for a full day and you do not have to worry about all those rashes if you apply them correctly.


  2. I have struggled over the years to find a good deodorant that will help with my sweating. I do sweat a lot and it’s hard to find something that works well for me.  I agree with you, as far as working out, there is really no solution to keep your armpits dry.  Thankfully I have never had a reaction to Aluminum Chloride, but I have known people who do.  A friend of mine has to use a prescription and I can only imagine how expensive that must be.  

    I never really thought about the metal factor before, and that being absorbed into the body. I suppose there are so many things in the food we eat, etc, that antiperspirants are no different.  Thanks for this awesome article breaking down everything about Aluminum Chloride, you sure know your stuff.

    1. Hi Steve,

      thanks for leaving a great comment!  If you need something to stop your sweating, look for antiperspirants and if it is excessive sweating, look for clinical strength antiperspirants because those are the ones that block your sweat glands.

      If you look for something to keep you fresh and will not stop your sweating at all, look for deodorants, because they are intended to stop unpleasant odors, while antiperspirants are made to stop sweating.  It took me years to really understand that concept; it confused me all the time.

      But it helped me to look for the correct solution to fix my problem.

      And yes, it gave me some peace of mind when I first learned that aluminum chloride is not nearly as unsafe as claimed by many!


  3. I have definitely had burns from putting on certain deodorant, is it usually because of the aluminum chloride and the fact that I am putting to much on? I don’t recall sweating that much when I placed it. Also, I have gotten swollen areas under my armpit but they seem to subside once I stoped deodorant use for a few days.

    1. Hi Jessie,

      I do know what you are talking about!  Aluminum chloride is only found in antiperspirants, but many deodorants are both: Deodorant and antiperspirants.  They are intended to stop your sweating and to make you smell good!

      Aluminum chloride is not the worst skin irritator when talking about antiperspirant/deodorant.  I think it is more the  deodorant part that contains chemicals to which our armpits are highly sensitive.  

      Aluminum chloride give you more a sense of prickling and of burning, while deodorants make you itch and have swollen armpits.  At least in my experience, aluminum chloride, if applied in the correct amount and correctly (it has to be applied to 100% dry armpits and preferably in the night which is when you sweat the least), it does not irritate your skin.

      Hope that helps,
