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

The formation of bentonite includes the change of volcanic glass to clay minerals; this needs hydration (taking up or mix with water) and a loss of alkalies, bases, and possibly silica, with the conservation of the textures of the original volcanic glass. Bentonite consists primarily of crystalline clay minerals belonging to the smectite group, which are hydrous aluminum silicates containing iron and magnesium in addition to either sodium or calcium. 2 kinds of bentonite are acknowledged, and the uses of each depend upon particular physical properties.

Sodium bentonites take in big quantities of water, swelling to lot of times their initial volume, and give rise to long-term suspensions of gellike masses. These have 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 conditioner to get rid of calcium from difficult water. Calcium bentonites are nonswelling and break down to a carefully granular aggregate that is extensively used as an absorbent clay in some cases called fuller’s earth.

Bentonite occurs in rocks that were deposited in the Ordovician to Neogene periods (about 488.3 to 2.6 million years ago). In the United States the principal manufacturers are Wyoming, Montana, California, Arizona, and Colorado. Crucial 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 happening mineral, which indicates that it took millions of 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 might discover, namely, the bottom of a body of water. And there it sat. In the case of the western bentonite that we utilize, the ash was blown out of volcanoes along the Northwestern Cascades and the Aleutian mountain ranges, brought by dominating winds and flowing water to be transferred into inland seas which covered much of Wyoming, Montana, South and North Dakota over ninety million years back. The inland seas served as big collection pots for sediment. With time the volcanic sediments built up to form multiple layers of different depths. As the inland seas started to dry up, the dissolved minerals started to concentrate which constantly required a growing number of chemicals and substances to share less and less liquid area. This concentration made aspects such as salt easily available to react with the silicates, aluminum, and magnesium that constitute the foundation of the bentonite molecules. This salt is what makes sodium bentonite from this region the really various and impressive product that it is. Other forms of bentonite are also readily available from other regions, however these mainly have high concentrations of calcium (Fuller’s earth), which offer these bentonites different properties (considerably less sealing homes when hydrated).

How does bentonite clay work?

Bentonite clay can remove contaminants from the body and help deal with oily skin.

Scientists think that bentonite clay works by adsorbing oils and dirt from the skin.

The theory is that bentonite clay adsorbs materials by sticking to their particles or ions. As the clay leaves the body, it takes the toxic substance or other particles with it.

When an individual uses it on the skin, bentonite clay might have the power to adsorb oils and germs. When they take in the clay, it might adsorb contaminants or other undesirable compounds from the digestive tract.

Bentonite clay contains natural minerals such as calcium, magnesium, and iron, which may offer fringe benefits.

Bentonite clay kinds from ashes. It gets its name from Fort Benton in Wyoming, where it occurs in large quantities. People can likewise discover this clay in other locations where ashes has actually settled into the ground. Montmorillonite clay, called after Montmorillon in France, is the same kind of clay.

The following list looks at the benefits of bentonite clay and what the research states.

Is bentonite clay safe?

It is generally okay to use bentonite clay on your skin and hair as long as you do not get any allergic reaction. Therefore, before using on a big part of your face or skin, apply just a little bit first. As the U. S. Fda (FDA) does not manage the production and labeling of cosmetics, it is tough to state how the products that contain bentonite clay will end up after their usage. Therefore, you require to attempt them out by yourself.

There are two reports of bentonite clay causing low potassium levels (hypokalemia)– one in a cat and the other one in a lady after oral intake. But the adverse effects can be credited to the intake of extreme amounts of bentonite clay.

Though security research studies suggest that bentonite clay is safe, there is a possibility they are polluted with poisonous metals such as arsenic, mercury and lead. The FDA has prohibited at least 2 top quality items of bentonite clay because of the presence (more than the allowable limitation) of lead in them. For this reason, constantly ask your doctor before taking any brand name of bentonite clay.

Eating a lot of bentonite clay can be a sign of an underlying condition called pica. Pica is a compulsive eating condition to eat items other than food. It is an indication that either your diet plan lacks minerals or you have a psychological problem.

There is a lack of security data in specific populations, such as pregnant and lactating women, children, older individuals and those with particular medical conditions. Hence, we recommend asking your doctor before taking bentonite clay. [7]
