Sodium Bentonite has high absorbency with clumping attributes while also being useful as both a soil and pond sealant. It is considered a safe, natural, nontoxic and inexpensive treatment for porous soils. Its swelling capacity gives Sodium Bentonite the ability to bond with soil and create an impenetrable barrier. Other uses of Sodium Bentonite include mud drilling, clumping cat litter, and as a bonding agent for feeds, medicines and cosmetics. Sodium Bentonite is even being investigated as an absorbing agent to remove E-Coli bacteria from food.
