Natural deodorants have taken the wellness world by storm, and for good reason. They skip the harsh chemicals, heavy fragrances, and aluminum compounds found in traditional antiperspirants, offering a cleaner, more mindful way to stay fresh.
But one ingredient has sparked plenty of debate: baking soda.
While some people swear by baking soda deodorant for its odor-fighting power, others find it too harsh for their skin. So, what’s the deal? Let’s break down the science, the pros and cons, and the best EarthHero options for every skin type.
H2: What Is Baking Soda Deodorant?
Baking soda (also known as sodium bicarbonate) has long been used as a natural deodorizer. You’ll find it in everything from toothpaste to household cleaners. In deodorant, baking soda helps neutralize odor by balancing pH and absorbing moisture from sweat.
It’s effective, affordable, and natural…so what’s not to love? Well, for some, the problem isn’t performance but sensitivity.
Baking Soda vs. Baking Soda-Free Deodorant

1) How Baking Soda Works
Baking soda works by creating a more alkaline environment on the skin, which helps prevent odor-causing bacteria from thriving. This means it can be a powerful, natural alternative to synthetic ingredients found in conventional deodorants.
But there’s a catch: the skin’s natural pH is slightly acidic, and baking soda’s alkalinity can disrupt that balance. Over time, this may lead to irritation, dryness, or redness, especially in the sensitive underarm area.
Baking soda is a known skin irritant when used in high concentrations or on sensitive skin because of its higher pH (around 9), compared to the skin’s normal pH (around 5.5). This difference can weaken your skin barrier, leading to inflammation or even contact dermatitis.
2) How Baking Soda-Free Deodorants Differ
Baking soda-free deodorants take a gentler approach. Instead of using sodium bicarbonate, they rely on natural alternatives like magnesium hydroxide, zinc ricinoleate, arrowroot powder, or activated charcoal to absorb moisture and fight odor without altering your skin’s natural balance.
Magnesium hydroxide, for example, neutralizes odor-causing bacteria without affecting pH, making it a top choice for those prone to irritation.
Formulation experts have noted that ingredients maintaining the skin’s natural barrier are better tolerated and less likely to cause rashes or sensitivity than high-alkaline agents like baking soda.
The Pros and Cons of Baking Soda Deodorant
Pros:
-
Highly effective at controlling odor
-
Natural and non-toxic alternative to aluminum-based antiperspirants
-
Absorbs moisture well to help you stay dry

Cons:
-
Can cause irritation or redness, especially on freshly shaved skin
-
May lead to itchiness or burning for those with sensitive skin
-
Not ideal for daily long-term use on compromised skin
In short, baking soda deodorants work brilliantly for some people, but if you have sensitive skin, you might find them too harsh.
Signs You Might Need a Baking Soda-Free Deodorant
If you’ve been using baking soda deodorant and noticed:

Persistent redness or dryness
