iron dust, which is an aggregate of iron particles with a size of less than 1mm, is the main raw material for powder metallurgy. According to the particle size, it is traditionally divided into five grades of coarse powder, medium powder, fine powder, micro-fine powder and ultra-fine powder. Iron powder composed of particles with particle size in the range of 150~500μm is coarse powder, particle size in the range of 44 ~ 150μm is medium powder, 10 ~ 44μm is fine powder, 0.5~10μm is extremely fine powder, and less than 0.5μm is ultra-fine powder.

When searching for effective skincare ingredients, the ground may not be the first place that comes to mind. But, clays (which are essentially types of dirt) are well known for their amazing cleansing and purifying properties. Natural clays have been used on the skin for centuries, and continue to be a popular ingredient in products today.In general, clays are soft, fine-grained mineral substances. There are different types of clay which vary in composition depending on the origin. While the properties of each clay varies, they are most commonly used in skincare because of their absorption properties. When applied, clay pulls oil from the skin, leaving it balanced and clean.Depending on your skin type, one clay may be better suited for your skin than another. For example, kaolin clay is a fine-grained clay with mild absorption properties, which makes it better for dry to normal skin. On the other hand, French green clay and bentonite clay have stronger absorption properties, making them a good fit for oily skin.

Natural clays have been used to heal skin infections since the earliest recorded history. Recently our attention was drawn to a clinical use of French green clay (rich in Fe-smectite) for healing Buruli ulcer, a necrotizing fasciitis (‘flesh-eating’ infection) caused by Mycobacterium ulcerans. These clays and others like them are interesting as they may reveal an antibacterial mechanism that could provide an inexpensive treatment for this and other skin infections, especially in global areas with limited hospitals and medical resources.Microbiological testing of two French green clays, and other clays used traditionally for healing, identified three samples that were effective at killing a broad-spectrum of human pathogens. A clear distinction must be made between ‘healing clays’ and those we have identified as antibacterial clays. The highly adsorptive properties of many clays may contribute to healing a variety of ailments, although they are not antibacterial. The antibacterial process displayed by the three identified clays is unknown. Therefore, we have investigated the mineralogical and chemical compositions of the antibacterial clays for comparison with non-antibacterial clays in an attempt to elucidate differences that may lead to identification of the antibacterial mechanism(s).The two French green clays used to treat Buruli ulcer, while similar in mineralogy, crystal size, and major element chemistry, have opposite effects on the bacterial populations tested. One clay deposit promoted bacterial growth whereas another killed the bacteria. The reasons for the difference in antibacterial properties thus far show that the bactericidal mechanism is not physical (e.g., an attraction between clay and bacteria), but by a chemical transfer or reaction. The chemical variables are still under investigation.Cation exchange experiments showed that the antibacterial component of the clay can be removed, implicating exchangeable cations in the antibacterial process. Furthermore, aqueous leachates of the antibacterial clays effectively kill the bacteria. Progressively heating the clay leads first to dehydration (200°C), then dehydroxylation (550°C or more), and finally to destruction of the clay mineral structure by (~900°C). By identifying the elements lost after each heating step, and testing the bactericidal effect of the heated product, we eliminated many toxins from consideration (e.g., microbes, organic compounds, volatile elements) and identified several redox-sensitive refractory metals that are common among antibacterial clays. We conclude that the pH and oxidation state buffered by the clay mineral surfaces is key to controlling the solution chemistry and redox related reactions occurring at the bacterial cell wall.

Bentonite clay adsorbs -- it attracts particles, like dirt on your skin. It also absorbs -- it takes in a lot of water. It’s used for face masks, and it’s also what makes pet litter clump.Bentonite has a high cation exchange capacity. That means clay, which has a negative charge, can attract positively charged ions. Those are minerals like magnesium, sodium, and potassium. Bentonite also has aluminum and silica.

Geophagy has been considered as an adaptive behavior in humans and animals (1) and the clays have been considered the healing materials from ancient times. As geophagia is an occasionally habits of animals and humans (babies and pregnant women), physiologically it is assumed that earth might have some beneficial effects on body function. Bentonite is absorbent aluminium phyllosilicate clay. It is named after Fort Benton, Wyoming where its largest sources are found. Its other name, Montmorillonite clay, stems from the region of France called Montmorillon, where it was first found. It has been used and eaten from ancient time till now as human believes in its therapeutic benefits. When it is mixed with water a paste is formed which has been used both externally and internally. In some places such as Iran, it has been widely used as a hair cleanser from old time. There is enough literature showing its safety after chronic oral consumption (2–6). As this clay is abundant, non-expensive and natural, this article aimed to review the scientific papers reporting the effects of this clay on body.

Bentonite Clay is the new natural beauty product that everyone is talking about. But Bentonite Clay is not a new product, it has been used for centuries by many ancient cultures including Indigenous Australians and North Americans, and the ancient Aztecs. Egyptians even used Bentonite to preserve their mummies. Today, the powerful cleansing and purifying properties of this natural product are still relevant and this has made Bentonite a highly sought-after product for those interested in natural beauty and wellness products.

If you're the type of person who slathers activated charcoal on your face, you've certainly heard of bentonite clay (also known as calcium bentonite clay). This multipurpose powder—made from volcanic ash that's been aged in prehistoric sea beds—is an ingredient in everything from beautifying hair and face masks to tonics.But does it actually work? History certainly makes a compelling case, as does some compelling research. While this is all encouraging, it still doesn't mean that bentonite clay delivers on every one of its head-to-toe, health-boosting claims or that it's safe to consume. So we dove into the research to help set the record straight. 

It is generally OK to apply bentonite clay on your skin and hair as long as you do not get any allergic reaction. Therefore, before applying on a large part of your face or skin, apply only a little bit first. As the U. S. Food and Drug Administration (FDA) does not regulate the production and labeling of cosmetics, it is difficult to say how the products that contain bentonite clay will turn out after their use. Therefore, you need to try 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 girl after oral consumption. But the side effects can be attributed to the intake of excessive quantities of bentonite clay.

In recent years, bentonite clay has become increasingly popular as a natural solution for various health and beauty issues. This ancient substance, known for its remarkable properties, has found a place in modern medicine and skincare routines. In this article, we will explore the origins of bentonite clay, its composition, and its many benefits. Additionally, we will discuss how to use bentonite clay effectively, the precautions to consider, and its role in alternative medicine. 

Bentonite is a clay that is available as a supplement. The primary ingredient in bentonite is hydrated aluminum silicate. Other nutrients in bentonite include calcium, magnesium, and iron, the composition of which varies according to the geographical location in which it is found.Once in the body, bentonite easily absorbs water. It remains in the digestive tract and is believed to bind and inactivate toxins and promote their excretion.1Alternate Names: Bentonite clay, montmorillonite
