bentonite clay

The scientific name for bentonite clay is hydrous silicate of alumina, which refers to its colloidal properties, or the ability to absorb up to 10 times its weight in water. In fact, because this material readily expands to many times its original mass, it is used in the oil and gas industry at drilling sites. Bentonite clay is also used as an environmental sealant for freshwater ponds and wells and in construction to create water-proof barriers around foundation walls.

Bentonite clay is also used in metal casting, poultry feed and in the manufacture of clumping cat litter. The versatility of this material earned a reputation as “the mineral with a thousand uses.” Originally known as “mineral soap,” bentonite received its modern common name in the late 19th century when an abundant reserve was found in the Benton Shale deposit near Rock River, Wyoming.

Background: The remarkable natural qualities of clays have long been appreciated worldwide and are used by humans and animals worldwide, every day.

The montmorillonite clay Bentonite is a medicinal form of earth used for centuries for nutritional supplementation and detoxification. This highly purified bentonite is used extensively personal care products and cosmetics. It is water-washed to remove impurities and lower any grit content.

It meets the standards of the National Formulary for use in pharmaceutical preparations such as, acne lotions, medicinal skin creams, ointments, skin creams, salves, tablet binding, powder preparations, and much more.

It is used in cosmetic preparations as a pigment binder and suspending agent. It is effective as a thickener in lotions, creams, liquid facial cleansers, anti-dandruff shampoos, body powders, deodorant sprays, deodorant sticks, and many others.

Bentonite is used for sealing freshwater ponds, irrigation ditches, reservoirs, sewage and industrial water lagoons, and in grouting permeable ground. It is an ingredient in detergents, fungicides, sprays, cleansers, polishes, ceramic, paper, cosmetics and applications requiring suspension and gellant properties.

Description: Bentonite is a purified, natural cream colored clay from deposits of weathered volcanic ash layered upon an ancient seabed formations. It is a highly mineralized clay with a 2:1 expanding crystal lattice and very plastic properties.

Bentonite- in response to water: "The sandwiched, stacked clay platelets shift apart. Bentonite attracts water to its negative face and magnetically holds water in place. This unique characteristic causes Bentonite to absorb 7 to 10 times its own weight in water,. It is capable of swelling up to 18 times its dry volume. Its molecular structure changes with the addition of water producing an electrical charge to which toxins bind. One quart of moistened bentonite presents a surface area of nearly 1,000 square yards!
