Baking-Soda-Free Deodorant: Why Some People Avoid Baking Soda
Baking soda is a familiar ingredient in natural deodorants. It can help neutralise odours, but some people find that deodorants containing it leave their underarms feeling uncomfortable. So what makes a baking-soda-free deodorant worth considering?
Why Can Baking Soda Irritate Skin?
Baking soda, or sodium bicarbonate, is alkaline, while the skin's surface is naturally slightly acidic. This acidic environment plays an important role in the skin barrier and its resident microorganisms.
An alkaline ingredient may affect that environment, although irritation depends on the complete formula, concentration and individual skin response. Baking soda is not necessarily irritating for everyone.
What Should You Look for Instead?
Choosing a deodorant without baking soda is a useful starting point if you prefer to avoid this ingredient. Look at the full formula, including fragrance, essential oils and alcohol, rather than judging a product by a single ingredient. Our guide to deodorant and sensitive skin covers this in more detail.
A well-designed deodorant should manage unwanted odour while fitting comfortably into your daily routine.
How Does ZINDEO Approach Odour?
ZINDEO Anti-odorant Cream uses a zinc-based formula without baking soda or aluminium salts. It focuses on managing body odour while supporting the skin microbiome, rather than preventing natural sweating.
The Fragrance-Free version also contains no added fragrance, essential oils or alcohol. In a dermatological patch test, 25 of 25 volunteers had no skin reaction, and the cream was classified as not irritating.
