Have you recently made the switch from conventional deodorants, only to find your skin reacting to a new "natural" formula?
You’re not alone. As controversy continues to grow around aluminum in antiperspirants, many people are turning to natural deodorants as a healthier, low-tox alternative.
One of the most popular natural ingredients is baking soda. It’s known for its odor-fighting powers, but here’s the catch: Baking soda isn’t the perfect solution for everyone. Because our underarms are naturally acidic, baking soda’s high alkalinity can throw off the skin’s pH balance, leading to irritation and discomfort, especially for those with sensitive skin.
That’s why making a mindful switch means more than choosing a product that says "natural" or "eco-friendly" on the label. It’s about knowing what works for your body.
In this guide, we’ll explore why people are stepping away from aluminum, why baking soda may not be the ideal solution either, and which gentle, effective alternatives are free from both. At EarthHero, we’ve got options that support your wellness and your values. No compromises needed.
Deodorant vs. Antiperspirant: What’s the Difference?
It’s easy to confuse the two, but deodorants and antiperspirants do different things: deodorants neutralize odor-causing bacteria, while antiperspirants block your sweat glands, typically using aluminum-based compounds.
While sweat is natural and healthy, antiperspirants are designed to stop it entirely. This has led some consumers to question whether preventing such a key bodily function is ideal in the long run.
Meanwhile, many natural deodorants skip the aluminum but turn to baking soda as an alternative odor-fighter, which may cause irritation for some people.
What’s The Deal With Aluminium in Antiperspirants?
Aluminum salts like aluminum chlorohydrate are used in antiperspirants to plug sweat glands and prevent perspiration. While the science is still developing, a few concerns have been raised over the years:
-
Skin irritation: Some people experience rashes or bumps after using aluminum-based formulas
-
Staining on clothes: Aluminum can react with sweat to cause yellowing of fabrics
-
Scientific debate: While not conclusive, studies have questioned whether aluminum compounds applied near breast tissue may have long-term health effects.
Because of these concerns, many are choosing to go aluminum-free as a precautionary step and relying on natural ingredients to manage odor instead.
What About Baking Soda?
Baking soda (sodium bicarbonate) is a popular ingredient in natural deodorants because it’s highly effective at neutralizing odors. However, it can also disrupt the skin’s natural pH, especially in the delicate underarm area.
Here’s why it might not be for everyone:
-
High alkalinity: Baking soda is much more alkaline than your skin’s natural barrier
-
Irritation risk: It can cause itching, redness, or even small rashes over time
-
Cumulative effects: Repeated daily use may lead to long-term skin sensitivity
If you’ve had a reaction to a natural deodorant, baking soda could be the reason, even if the label says it’s “gentle.”
So What’s The Solution? Benefits of Baking Soda Free Deodorants
The good news is you can choose a deodorant that skips both aluminum and baking soda and embrace gentler, more skin-supportive formulas.
Here’s what you can expect when you make the switch:
-
Soothes sensitive skin
-
Baking soda free options are often enriched with ingredients like magnesium, arrowroot powder, and plant oils to calm and protect.
-

Without high alkalinity, your skin can better maintain its natural pH and moisture barrier. -

Just like switching from antiperspirants, going baking soda free is about listening to your body and finding what truly works for you.
