Magnesium Hydroxide

What it does
Magnesium hydroxide is used to help neutralize odor by inhibiting the growth of odor-causing bacteria. It does not function as a cleanser or lathering agent.

What it feels like on skin
In finished products, it’s generally not perceptible on the skin.

Why it’s used
Magnesium hydroxide raises pH in a way that makes it difficult for odor-causing bacteria to thrive, without blocking sweat glands. It’s commonly used in deodorant formulations for this reason and may appear in soap or body products designed for odor control.
