There are two types of bentonite clay, depending on the ratio of key minerals they contain: sodium bentonite clay and calcium bentonite clay. They have similar properties, with subtle nuances. While calcium bentonite is used on the body, both internally and topically, sodium bentonite has more industrial uses.

Sodium bentonite is extremely absorbent and adsorbent – meaning it has the properties to swell and draw pollutants into its internal structure (absorb), as well at being able to attract positively charged substances (such as toxins) to its negatively charged surface (adsorb). It is these properties that make Sodium Bentonite – also known as Swelling Clay – such a powerful purifying substance.

Sodium bentonite clay is used as a natural sealant, such as to seal roads, lagoons, landfills and ponds. It has natural swelling abilities, swelling 15–18 times its dry size when combined with water, making it an effective “hole plug.”

It’s also low-cost and environmentally safe because it contains no chemicals, additives or toxins. It’s commonly mined in the state of Wyoming.

Both types of bentonites contain a percentage of other minerals, as well as sand and silt that is filtered out. But because calcium bentonite is a non-swelling bentonite, it doesn’t serve the same purposes for industrial uses.
