Application
Bentonite Nanoclay serves multiple purposes across various industries due to its unique properties. As a fine, crystalline, clay-like mineral, it forms a gelatinous suspension when mixed with water, allowing it to be used as an effective adsorbent, particularly in the manufacturing of paper and iron castings. In the pharmaceutical field, Bentonite Nanoclay functions as a suspending agent, helping to stabilize and formulate suspensions, gels, and sols, as well as suspending powders in aqueous preparations and creating cream bases with oil-in-water emulsifying agents. Its strong adsorbing capacity makes it useful in adsorbing cationic drugs to control their release, mask tastes, and as a potential diagnostic agent for imaging applications. Additionally, it finds applications in cosmetics and food products, and is being explored for therapeutic uses, such as adsorbing lithium in cases of poisoning. Bentonite Nanoclay's versatility stems from its composition of hydrated aluminum silicate, enabling its use in diverse fields such as metallurgy, soap manufacturing, and petroleum refining.

Color/Form
A clay containing appreciable amounts of the clay mineral montmorillonite; light yellow or green, cream, pink, gray to black solid;The color in the massive condition varies from yellowish-white to almost black. The powder is cream colored to pale brown.;Light to cream-colored impalpable powder;The Clay Spur benonite usually ranges from 0.5 to 2 meters thick ... generally light yellowish green on the outcrop, becoming bluish green away from the outcrop.;Southern or subbentonites are waxy and vary from blue when fresh to yellow when weathered.;Tertiary bentonite ranges from white to gray to yellow;Texas calcium bentonites range from 0.5 to 3 meters thick and varies from yellow to green to dark brown.;Cheto Arizona bentonite is white to light gray.

Other Experimental
Resists high temperatures & may be sterilized by heat;Lamellar aluminum silicate, each lattice layer is sheet of hydrated alumina sandwiched between 2 silica sheets;Very fine powder free from grit, nearly white but may be pale buff or cream color; insoluble in water or acids; odorless with slightly earthy taste; it does not swell in organic solvents /Bentonite USP/;Feels greasy and soap-like ... has a high cation exchange capacity;Interstitial water held in the clay mineral lattice is an additional major factor controlling the plastic, bonding, compaction, suspension and other properties of montmorillonite-group clay minerals;The property of forming gels is very much increased by addition of small amt of alkaline substances such as magnesium oxide.;It has the property of forming highly viscous suspensions or gels with not less than ten times its weight of water.;Forms colloidal suspension in water with strongly thixotropic properties. There are two varieties: (1) sodium bentonite (Wyoming or western), has high swelling capacity in water, and (2) calcium bentonite (southern), with negligible swelling capacity.;The high-swelling Wyoming or sodium bentonites contain ca 30% moisture when delivered to the plant. The Southern or calcium bentonites have ca 25% moisture. The processed bentonite generally contains only 7-8% moisture, although because bentonite is hygroscopic, it may contain considerably more moisture when used.;Bentonites in which sodium montmorillonites are the major mineral constituent have a high swelling capacity.;Bentonites in which calcium montmorillonites are the major mineral constituent commonly have a low swelling capacity. The clays are commonly referred to as Southern or subbentonites.
Stability
Suspensions are most stable at a pH above 7.
