Bentonite Clay
What is Bentonite Clay?
Bentonite Clay is a natural clay formed from volcanic ash that is composed mostly of montmorillonite. It is named after Fort Benton, Wyoming, where it was first identified.
This clay is used in a variety of personal care products, especially in hair and skin care, for its ability to absorb oil and impurities. While some claim it detoxifies and purifies, scientific evidence is mixed and largely anecdotal.
When you see Bentonite Clay on a label, it is often included for its textural properties, acting as a thickening agent or to improve product stability.
Commonly found in: Hair Care, Face Masks, Body Wraps, Toothpaste, Deodorants
Benefits
- May absorb excess oil and impurities in hair and skin care products.
Bentonite clay is generally recognized as safe (GRAS) for use in food and cosmetics by the FDA.
While some studies suggest it may have absorbent properties, scientific evidence on its health benefits is limited and mostly anecdotal.
Bentonite clay is mineral-based and suitable for vegan use.
