Introduction
Did you know that baking soda, that white product found in almost every kitchen, is much more than just a raising agent? Used for centuries, it has become a staple for cleaning, cooking, and even homemade cosmetics. But beware: behind its many uses also lie risks and misconceptions.
In this article, we will explore the known and unknown uses of baking soda, separate fact from fiction, and above all, remind you of the essential precautions to avoid accidents (irritations, imbalances, interactions).
Understanding the problem: what is baking soda?
Sodium bicarbonate (hydrogen carbonate) is an alkali salt with the formula NaHCO₃. It is a white powder and has the following properties:
- Alkalizing : it neutralizes acids.
- Gentle abrasives : it allows cleaning without scratching.
- Deodorizing : it absorbs odors.
- Effervescent : it reacts with acids, producing carbon dioxide.
Common uses of baking soda
1. In the kitchen
Bicarbonate is used as a raising agent in cakes, breads, and cookies. It is also sometimes added to green vegetables to preserve their color.
2. For cleaning
It cleans surfaces, deodorizes the refrigerator, descales faucets, and unclogs drains (with vinegar). It’s an eco-friendly and economical ally.
3. In homemade cosmetics
It is sometimes used as an exfoliant, deodorant, or for teeth whitening. These uses are often discouraged by dermatologists and dentists due to its abrasiveness and alkalinity.

- Skin irritation : redness, itching, dryness.
- Burns : in case of prolonged contact with the skin.
