As a subject matter expert in the field of chemistry and personal care products, I can provide you with an accurate explanation of the role of baking soda in deodorants.

Baking soda, or sodium bicarbonate, is a common ingredient in many deodorants due to its ability to neutralize odors. Here's how it works:


1. Odors are caused by acids: The human body produces sweat, which is often acidic due to the presence of bacteria on the skin. These bacteria break down sweat into compounds that have a strong, unpleasant smell.


2. Neutralizing the acids: Baking soda is a mild base, and when it comes into contact with the acidic compounds produced by bacteria, it neutralizes them. This neutralization process helps to reduce or eliminate the bad smell.


3. Absorbing moisture: Baking soda also has the ability to absorb moisture, which can help to keep the underarms dry. Dryness is important because it reduces the environment in which bacteria can thrive, thus further reducing odor.


4. Non-irritating properties: Many people prefer baking soda in their deodorants because it is less likely to cause skin irritation compared to other ingredients that are used in antiperspirants.

However, it's important to note that baking soda can sometimes cause skin irritation for sensitive skin types, so it's not suitable for everyone.
