Bentonite, clay formed by the alteration of minute glass particles stemmed from volcanic ash. It was called for Fort Benton, Mont., near which it was discovered.

The development of bentonite includes the modification of volcanic glass to clay minerals; this needs hydration (taking up or combination with water) and a loss of alkalies, bases, and potentially silica, with the conservation of the textures of the original volcanic glass. Bentonite consists mainly of crystalline clay minerals belonging to the smectite group, which are hydrous aluminum silicates consisting of iron and magnesium along with either sodium or calcium. 2 kinds of bentonite are acknowledged, and making uses of each depend upon particular physical properties.

Salt bentonites soak up large amounts of water, swelling to often times their original volume, and trigger irreversible suspensions of gellike masses. These have actually been used to seal dams; in bonding foundry sands, asbestos, and mineral wool; as drilling muds; in portland cements and concrete, ceramics, emulsions, insecticides, soaps, pharmaceuticals, and paints; in the manufacture of paper; for clarifying water, juices, and alcohols; and as a water softener to get rid of calcium from tough water. Calcium bentonites are nonswelling and break down to a finely granular aggregate that is commonly used as an absorbent clay sometimes called fuller’s earth.

Bentonite happens in rocks that were transferred in the Ordovician to Neogene durations (about 488.3 to 2.6 million years ago). In the United States the primary manufacturers are Wyoming, Montana, California, Arizona, and Colorado. Important world producers are Greece, Japan, Italy, Brazil, Romania, Germany, Mexico, Argentina, Spain, India, Hungary, Poland, Canada, Turkey, and Cyprus. [1]

Bentonite History

Bentonite is 90 million years old.

Bentonite is a naturally occurring mineral, which suggests that it took countless years to become what it is. The story of bentonite started in volcanoes numerous million years ago when the molten lava was ejected (typically explosively) spreading volcanic ash over most of the existing earth. This violent start for the bentonite mineral was just the start. As this ash settled to the earth, it was deteriorated by rain and wind to the most affordable resting place it could find, particularly, the bottom of a body of water. And there it sat. In the case of the western bentonite that we use, the ash was burnt out of volcanoes along the Northwestern Cascades and the Aleutian mountain ranges, brought by dominating winds and flowing water to be deposited into inland seas which covered much of Wyoming, Montana, South and North Dakota over ninety million years ago. The inland seas acted as huge collection pots for sediment. Gradually the volcanic sediments built up to form several layers of various depths. As the inland seas began to dry up, the liquified minerals began to concentrate which continually required a growing number of chemicals and substances to share less and less liquid area. This concentration made aspects such as sodium freely available to react with the silicates, aluminum, and magnesium that make up the backbone of the bentonite particles. This salt is what makes salt bentonite from this area the really various and amazing product that it is. Other types of bentonite are likewise readily available from other areas, however these mainly have high concentrations of calcium (Fuller’s earth), which provide these bentonites different homes (significantly less sealing properties when hydrated).

Fda (FDA) does not control the production and labeling of cosmetics, it is tough to state how the products which contain bentonite clay will end up after their use. Therefore, you require to attempt them out by yourself.

There are 2 reports of bentonite clay causing low potassium levels (hypokalemia)– one in a feline and the other one in a girl after oral usage. But the side effects can be credited to the intake of extreme amounts of bentonite clay.

Though security studies suggest that bentonite clay is safe, there is a possibility they are polluted with toxic metals such as arsenic, mercury and lead. The FDA has actually prohibited at least 2 branded items of bentonite clay because of the presence (more than the permissible limit) of lead in them.
