How Magnesium Neutralizes Odor
How Magnesium Fights Odor-Causing Bacteria
Magnesium plays a key role in keeping underarm odor at bay by balancing the skin's pH and creating an environment that's less inviting for odor-causing bacteria. Thanks to its natural antimicrobial properties, magnesium chloride can slightly raise the skin's pH, making it harder for bacteria to thrive[4]. This ability to combat bacteria and reduce odor is supported by clinical research.
In fact, studies have shown that magnesium-based formulations can cut malodor by more than 40%, with 84% of participants reporting long-lasting protection. ICL's scientists developed a molecule called CareMag® D, derived from the Dead Sea, which demonstrated these results in sniff tests[5].
"It prevents odor production by controlling bacteria growth on the skin, without blocking the sweat glands and disrupting the natural cooling mechanism of the body." - ICL Innovation [5]
Magnesium hydroxide, another key compound, works by staying on the skin's surface. It balances pH and absorbs moisture, effectively neutralizing bacteria without deeply penetrating the skin. This insoluble compound helps keep underarms dry while allowing natural sweating to occur. Research confirms that it remains on the skin's surface, ensuring it doesn't get absorbed into the body[2]. These characteristics make magnesium a standout choice compared to traditional deodorant ingredients.
Magnesium vs. Aluminum and Baking Soda
To understand why magnesium is becoming a go-to ingredient for natural deodorants, it helps to compare it with other common options like aluminum and baking soda:
| Ingredient | How It Works | Skin Compatibility | Potential Side Effects |
|---|---|---|---|
| Magnesium | Balances pH and neutralizes bacteria on the surface | Gentle; supports skin's natural pH | Minimal irritation; ideal for sensitive skin |
| Aluminum | Blocks sweat ducts by forming gel plugs | Can cause irritation and clogged pores | Skin irritation, blocked pores, potential staining |
| Baking Soda | Absorbs moisture and neutralizes odor with high alkalinity | Highly alkaline; may disrupt skin barrier | Irritation, dryness, discoloration, risk of candidiasis |
Aluminum-based antiperspirants work by physically blocking sweat ducts, which can lead to irritation and clogged pores. Magnesium, on the other hand, allows the body to sweat naturally while keeping odors under control. As MAGS Skin puts it:
"Magnesium lets your body do what it's designed to do - sweat. It just keeps odor away while keeping your skin calm and balanced." - MAGS Skin [6]
Baking soda, though effective at absorbing moisture, has a highly alkaline nature that can disrupt the skin's natural barrier. This can result in dryness, discoloration, or even conditions like candidiasis[2][7]. Magnesium hydroxide offers a gentler alternative, as its pH is closer to that of the skin. Its larger molecular structure also enhances its ability to absorb moisture and neutralize bacteria[8].
"Unlike aluminum-based antiperspirants, which work by clogging pores to reduce sweat production, magnesium hydroxide targets bacteria responsible for unpleasant odors. By creating an alkaline environment on the skin's surface, it effectively inhibits bacterial growth, keeping underarms fresh and odor-free." - Gentle Moose [3]
This comparison underscores why magnesium-based deodorants are becoming a popular choice for those seeking effective odor control without sacrificing skin health or interfering with natural sweating.

Skin Benefits of Magnesium
Magnesium does more than just neutralize odor - it also supports overall skin health in impressive ways.
Gentle on Sensitive Skin
Magnesium is kind to sensitive skin, working naturally with your body to soothe irritation. Its anti-inflammatory properties help calm redness and swelling caused by shaving or friction, making it a great choice for those with easily irritated skin [10]. Plus, magnesium’s ability to balance pH levels helps maintain your skin's natural harmony.
Pro tip: If your skin reacts strongly to citrus essential oils, opt for formulations that are free of citrus to avoid potential irritation [11].
Strengthens the Skin's Natural Barrier
Magnesium not only soothes but also strengthens your skin’s defenses. It helps maintain hydration and elasticity - two essentials for keeping skin healthy and resilient [1]. Unlike aluminum, which clogs sweat glands, magnesium takes a gentler approach by neutralizing odor-causing bacteria while allowing your body to sweat naturally. This surface-level action ensures your skin’s protective barrier stays intact, promoting long-term comfort and health.

Health and Safety Considerations
When choosing personal care products, understanding the safety of their ingredients is essential.
Concerns About Aluminum-Based Deodorants
Aluminum compounds, commonly found in antiperspirants, work by blocking sweat ducts. However, this has raised concerns, as studies suggest that up to 60% of applied ingredients may be absorbed into the bloodstream [13][14][15].
Some potential health risks linked to aluminum-based products include breast cancer, hormone disruption, kidney disease, bone disease, and Alzheimer’s disease [13]. These concerns have led many people to seek safer alternatives. In fact, the FDA mandates warning labels on antiperspirants for individuals with kidney disease [12][13].
Despite these worries, experts like Dr. Susan Massick, a dermatologist and Associate Professor at Ohio State Wexner Medical Center, emphasize that:
"The claim that aluminum-containing antiperspirants cause cancer is a myth that has been debunked in the minds of doctors and scientists, and so it's time to put lingering doubts for consumers to rest." [14]
A 2014 review also found no evidence linking aluminum-containing antiperspirants to an increased risk of cancer [14]. Still, the availability of alternatives has encouraged many consumers to make the switch, preferring to avoid potential risks altogether.
Magnesium as a Safe Alternative
Magnesium-based deodorants offer a natural and safer option for those concerned about aluminum. Unlike aluminum, which blocks sweat glands, magnesium neutralizes odor naturally without interfering with your body’s ability to sweat [9]. This makes it a gentler choice for maintaining skin health.
Magnesium hydroxide is classified as "generally recognized as safe" (GRAS) by the FDA [18]. Importantly, it does not appear to absorb through the skin, eliminating concerns about systemic absorption [18]. This safety profile makes magnesium particularly appealing for people with sensitive skin or health conditions. Unlike aluminum-based products, magnesium deodorants do not require FDA warnings for kidney disease patients. However, individuals with medical conditions requiring them to avoid magnesium should consult their doctor before use [18].
Switching to magnesium deodorants is usually an easy transition. It may take a week or two for your body to adjust, during which mild stinging or itching can occur. These sensations are temporary and typically resolve as your skin adapts [19][20]. Allergic reactions to magnesium hydroxide are rare but possible. Signs of sensitivity, such as rash, hives, or redness, should prompt discontinuation and consultation with a healthcare professional [18].
Interestingly, nearly half of Americans and 70 to 80 percent of older adults have a magnesium deficiency [16]. Since magnesium is vital for over 300 biochemical functions in the body [15], using magnesium-based deodorants may offer additional wellness benefits. Research suggests that the skin absorbs magnesium more effectively than oral supplements, potentially supporting overall health while keeping you fresh [15].
For those looking to reduce aluminum exposure, magnesium deodorants provide a well-researched alternative that works in harmony with your body’s natural processes.
Eco-Friendly and Conscious Consumer Choices
The demand for eco-friendly personal care products is on the rise, and the deodorant industry is no exception. With the market expected to hit $30 billion by 2030, brands are under pressure to embrace sustainable practices [25]. Millions of deodorant containers end up in landfills and oceans annually, making the push for eco-friendly alternatives more urgent than ever [24]. This has led many companies to rethink their packaging strategies.
Eco-Friendly Packaging Options
Traditional deodorant packaging often combines materials that are difficult - or even impossible - to recycle, leading to significant waste [24]. For instance, 70% of recyclable plastics in Europe still end up in landfills or oceans, while 40% of the world's traded wood goes to the pulp and paper industry [22].
Refillable packaging offers a practical solution by allowing consumers to reuse containers multiple times, cutting down on single-use plastic waste. This aligns with the principles of a circular economy, where materials are reused and recycled instead of being discarded [21].
"Deodorant refillable packaging represents a step towards environmental sustainability in the beauty and personal care industry." – APG Packaging [21]
Biodegradable packaging is another promising alternative. Unlike conventional plastic containers that linger in the environment for decades, biodegradable options - made from renewable resources like bamboo or cornstarch - decompose naturally. These materials not only reduce production resource use but also minimize post-consumer waste [23]. When composted properly, they break down into organic matter that enriches soil and supports plant growth [23].
The move toward sustainable packaging is not just an environmental initiative; it's also becoming a business necessity. Studies reveal that 90% of CEOs see sustainability as key to long-term success [22], reflecting the growing consumer demand for greener products.
