Benefits of Aluminum-Free Deodorant

Geraldine Orentas

Today, it’s fairly easy to find a myriad of natural deodorants and antiperspirants available at your nearby store, all claiming to be aluminum-free. While most people continue to use traditional antiperspirants, there are many reasons for switching things up to avoid certain ingredients like aluminum in a product that we use, well, every day. 

In favor of a cleaner, greener, and potentially safer underarm skin routine, the benefits of aluminum-free deodorant seem to be catching up with most people. 

To better understand the debate between aluminum and aluminum-free deodorants, let’s break down this controversial ingredient -- and, why switching to an aluminum-free deodorant can be the best thing you’ll do for your underarms.

What is Aluminum?

Now you know the benefits of aluminum-free deodorants -- but it’s also important to understand the ingredient in question. 

Aluminum is an element and one of the most abundant metals on our planet. In antiperspirants, aluminum is present in ingredients like aluminum salts. These can appear in ingredient labels with names like aluminum chloride, aluminum chloralhydrate and aluminum zirconium. There are about 18 aluminum-based ingredients currently approved by the Food and Drug Administration (FDA) for use in over-the-counter antiperspirants. 

Why is Aluminum in Antiperspirant Deodorants?

Most antiperspirants work to prevent sweat. These ingredients are all popular for their sweat- and odor-blocking properties. They absorb into the skin and temporarily block the pores and sweat glands, preventing sweat from ever reaching the surface. 

Antiperspirants contain aluminum to help minimize body odor by inhibiting the bacteria that feed on sweat from reaching the sweat glands and causing odor.  

On occasions, prescription-strength antiperspirants can help treat conditions like hyperhidrosis, which causes too much sweating. These antiperspirants have about 10-30% more aluminum salts than the ones in drug stores or over-the-counter.

Concerns About Aluminum in Deodorants

While aluminum was the go-to ingredient for antiperspirants for decades, new research has raised health concerns related to the long-term use of deodorant products with aluminum. There are three main health issues usually cited about aluminum deodorants:

  • Breast Cancer: While the American Cancer Society says there’s no scientific evidence that using antiperspirants causes or worsen breast cancer, they acknowledge that aluminum salts can be collected in breast tissue. A 2018 study showed that too much aluminum in the body could alter how the body produces or responds to estrogen. Another medical study surveyed 209 women with and without breast cancer about their antiperspirant use and found that the group with breast cancer self-reported using antiperspirants several times a day. 
  • Kidney Disease: The National Kidney Foundation advises people with kidney disease to avoid most skincare products with aluminum. This is mainly because your kidneys help your body get rid of aluminum and other waste products. If your kidneys aren’t working as optimal, this can allow an aluminum build-up in the body and trigger health problems. 
  • Alzheimer’s Disease: Back in the 1970s, aluminum was a possible suspect in the onset of Alzheimer’s disease, a degenerative brain disease. One analysis of studies found that adults with Alzheimer’s disease tend to have higher levels of metals like aluminum, calcium and mercury in their blood.

5 Benefits of Aluminum-Free Deodorants

There are many benefits to switching to a natural deodorant. However, when you’ve been using an aluminum-based deodorant or antiperspirant, there may be an adjustment period that can be a bit annoying for some people. Still, once your body adapts to the new deodorant, you’re likely to enjoy many of its benefits. 

1. They’re Much Gentler on the Skin

Many antiperspirants contain ingredients that can cause irritation and inflammation. Ingredients like alcohol can be very drying to the skin and trigger rashes and irritation. One study showed that antiperspirants (but not deodorants) could adversely affect the skin’s microbiome by disrupting the natural bacteria balance on the surface. 

Switching to an aluminum-free deodorant can provide some much-needed comfort and relief for people with dry or sensitive skin. Natural deodorants instead have ingredients like natural botanicals to help control odor-causing bacteria while nourishing and caring for your sensitive underarm skin at the same time. 

2. You Can Still Control Sweat

You’re supposed to sweat. Sweating is how our bodies regulate temperature and release toxins – it’s a natural process of our body that we need for our health. 

While deodorants without aluminum don’t necessarily claim they can fight sweat, you can still keep it under control with natural ingredients. For example, our natural deodorant contains natural starches like arrowroot powder and potato starch that help absorb sweat and moisture. 

Unlike pore-clogging ingredients found in antiperspirants, sweat-controlling ingredients in aluminum-free deodorants won’t disturb your body’s natural sweating process. Some people even find that they sweat less after switching to natural deodorants. 

3. They’re Great for Blocking Odor, Safely

Most aluminum-free deodorants do what they are meant to: block or neutralize odor. They just do it in a way that is typically safer for our bodies. Using natural botanicals, essential oils and ingredients that fight odor causing bacteria, these deodorants can prevent odor from ever occurring in the first place. 

Mother Dirt's natural deodorant is formulated to preserve a healthy microbiome all while regulating and neutralizing odor-causing bacteria. This way, we’re not disrupting the skin’s natural ecosystem by wiping out all bacteria as other deodorants do. 

4. Keep Your Underarm Pores Clear

Clogged pores are trouble waiting to happen. They can cause acne, cysts and a myriad of skin issues that can be uncomfortable. Aluminum-based antiperspirants actually work by temporarily clogging the pores, which is why people who use them can often struggle with pimples or irritation. On the contrary, natural deodorants don’t have pore-blocking ingredients that disrupt your skin’s natural sweating process.

5. Avoid Irritation and Pit Stains

Some antiperspirants may contain irritating ingredients like alcohol or high levels of aluminum that can be too drying and irritating, particularly for people with sensitive skin. Besides, clogging the sweat ducts in your underarms can lead to irritation, rashes and even skin color changes.

Our natural deodorant is free from synthetic fragrances, phthalates, alcohol, and aluminum to prevent some side effects of common harsh irritants. Plus, it contains ingredients like sunflower and coconut oils that can help keep skin nourished and calm. 

One of the culprits of dark and yellow stains on your shirts is the aluminum found in most antiperspirants. This is because when aluminum mixes with sweat, it creates a reaction that can leave behind stains in your clothes. Since natural deodorants don’t contain aluminum, you don’t have to worry about that. 

Mother’s Dirt Natural Deodorant 

Our deodorant is formulated to neutralize odor effectively and balance your microbiome. The natural starches help absorb sweat and moisture that rises to the surface to help your skin stay dry throughout the day. Plus, a powerful blend of postbiotics helps promote a healthy microbiome and overall skin health. At last, a hint of lemongrass oil helps neutralize odor and keep you feeling fresh and scented all day long. It‘s vegan, alcohol-free, cruelty-free, and most importantly, aluminum-free.

Also, it works as an excellent primer for our patented AO+ Restorative Mist and fits easily in our Active Probiotic System for even better results. 

If your goal is to control odor and sweat, an aluminum-free deodorant can help you keep it under control without clogging your pores or potentially causing metal build-up in your body. 

Wrapping Up

An aluminum-free deodorant has benefits for your skin and the environment. Plus, it can be as effective as aluminum-based ones. Finding the right one for your body and lifestyle may take some time to adjust. But, once you’ve successfully made the switch, you’ll notice a significant improvement and difference in your underarm skin’s health.
