Baking Soda
Simple Chemistry, Effective Odor Control
Baking Soda, also known as sodium bicarbonate, has been used for generations in everything from cooking and cleaning to personal care. In skin care, its value lies in its ability to absorb moisture and neutralize odor—when used thoughtfully and in the right applications.
Why Baking Soda Is Used in Natural Deodorant
Baking soda plays a very specific and well-understood role in some of our deodorant formulations. Its effectiveness comes down to basic chemistry.
Moisture Absorption
Baking soda is a fine, porous powder with excellent moisture-absorbing properties. Its physical structure allows it to absorb perspiration and surface moisture, helping underarms feel drier. Less moisture also means fewer conditions that contribute to odor development.
Odor Neutralization
Body odor isn’t caused by sweat itself—it develops when skin bacteria break down components of sweat into acidic, odorous compounds. Baking soda is naturally alkaline (basic), so it helps neutralize these acids through a simple acid–base reaction. When the acids are neutralized, the odor is reduced.
In addition, the higher pH environment created by baking soda is less favorable for the bacteria responsible for odor formation, helping limit odor development without masking it with fragrance.
A Note on Skin Sensitivity
Baking soda may not be for everyone. While some people with sensitive skin choose to avoid it, others actually prefer it because it is the only thing that actually works for them!
This is why we offer both baking soda and baking soda–free deodorant options. Skin is personal, and what works beautifully for one person may not work for another
Clearing Up a Common Myth
Baking soda does not contain aluminum and never has.
Confusion often arises because baking powder may contain aluminum-based ingredients.
Baking soda and baking powder are not the same thing. When purchasing baking powder, look for an aluminum-free label if that is a concern.
