Kaolin clay (KC), also known as China clay, is the inorganic mineral ingredient that is widely used in a number of cosmetic products. These products are famous for their oil absorbing properties, reduced shine and translucent properties. They are great for finishing a flawless look as they are great for hiding imperfections. KC products are the perfect primer for oily skin. Their benefits expand their applications in various skin care and repair treatments. Its earthy origin complements human skin with natural essences that brings out the benefits in all mineral ingredients.

 
Types
The mineral has a low shrink-swell property and low cation exchange capacity.  It is formed by the chemical weathering of aluminum silicate minerals like feldspar. Different forms of kaolin come from various locations. The pink-orange-red color of kaolin clay is given by the iron oxide. Lightly concentrated clays are typically white, yellow and light orange in color. Since the clay is produced from rock weathering, the rock composition typically differentiate type of kaolin clay by color.

Kaolin Clay in Mineral MakeupThe excellent coverage, absorption and adhesion properties of kaolin clay make it a great ingredient for most cosmetic products. It is perfect as an opaque white base of colors and its fine texture allows any mineral makeup to easily slide and apply on the skin. This features allows the ingredient to finish a flawless effect in effectively hiding imperfections and fine lines even at medium coverage.
One thing that is known among kaolin clays, white or pink, is that they bring in significant skin care benefits. One great property of kaolin clays is that it provides effective sun protection. Also, it does not draw oil the oil of the skin making it soft and supple. Its oil control properties allow the makeup to stay on longer, withstanding perspiration and wet or humid conditions. In some products, the ingredient allows some mineral makeup to feature water and transfer resistant features.
 
As the mildest of all clays, it is suitable for use on individuals who are managing skin conditions such as dryness, acne, rosacea, sun damage and cosmetic surgery recovery. In bringing in the natural healing and nourishing essences the earth, it aids in healing these skin problems. Its natural properties were found to be effective in stimulating circulation on the skin, making it ideal for cleansing and exfoliating skin treatments.
 
Kaolin clay is the beneficial for all skin types. Its mild and versatile properties explain why it is one of the highly prized ingredients among cosmetic and skin care products particularly in mineral makeups.

Other uses of Kaolin

Kaolin has traditionally been used internally to control diarrhea. Kaolin has also been used topically as an emollient and drying agent. Specifically, it has been used to dry oozing and weeping poison ivy, poison oak, and poison sumac lesions. It has also been used as a protectant for the temporary relief of anorectal itching and diaper rash.

History

Kaolin has been used commercially and medicinally for hundreds of years. It is currently used in the manufacture of pottery, bricks, cement, ceramics, paints, plastering material, color lakes (insoluble dyes), and insulators. As a raw material, it is commonly found in paper, plastics, cosmetics, and pharmaceuticals, and it is also used in pharmaceutical preparations as a filtering agent to clarify liquids. Evidence also suggests that kaolin may be useful in the decolorization of dye wastewater via the electrocoagulation method. When applied topically, it serves as an emollient and drying agent. When ingested, it acts as an adsorbent to bind GI toxins and control diarrhea.

Kaolin has been added to dusting powders and is used as a tablet excipient. It is also utilized in a variety of automated laboratory chemistry tests, including the determination of activated clotting time (ACT) and in the serodiagnosis of tuberculosis using the kaolin agglutination test (KAT). Kaolin has also been used experimentally to induce hydrocephalus in animal models in order to assess the effects of the condition on sensorimotor development.

Chemistry

Kaolin has the approximate chemical formula of H2 Al 2 Si 2 O 8 (H 2 O) and is a white or yellow-white powder that has a slightly oily feel. It is an environmentally benign aluminosilicate mineral that is insoluble in water. Light kaolin is the preferred material for use in pharmaceutical preparations. The finely divided particles yield a very large surface area that adsorbs a wide variety of compounds.

Kaolin Uses and Pharmacology

Diarrhea

When given orally, kaolin adsorbs substances from the GI tract and increases the bulk of feces. Kaolin improves stool consistency within 24 to 48 hours; however, it does not decrease the number of stools passed or reduce the amount of fluids lost.

Clinical data

Antidiarrheal preparations containing kaolin have been used in the treatment of enteritis, cholera, and dysentery. Kaolin preparations, however, have no intrinsic antibacterial activity and should not be used as the sole treatment in infectious diarrheas.

Insecticide

Kaolin has been used as an insecticide against various arthropods that affect crops. Specifically, kaolin is commonly incorporated into particle film technology for purification, sprayed onto crops in the form of an aqueous suspension, and allowed to dry, yielding its insecticidal effects and leaving a white appearance. Kaolin is nontoxic to plants and animals, as it remains chemically inert over a range of pH values. You mix it with water until you have a milky solution and spray it on the plants. Kaolin acts as a physical barrier preventing insects from reaching vulnerable plant tissue. It acts as a repellent by creating an unsuitable surface for feeding or egg-laying. The uniform white film may also disrupt the insectís host finding capability by masking the color of the plant tissue. Furthermore, particles of kaolin act as an irritant to the insect. After landing on a treated surface, particles of kaolin break off and attach to the insectís body triggering an excessive grooming response that distracts the pest.. It can be mixed with diatomaceous earth, another nontoxic and inert substance that damages their exoskeleton and cause them to dehydrate.

Clay      
 
Chemical Properties
 

Clay is a natural substance occurring in great abundance in nature. It is constantly being formed on the earth's surface as a result of the weathering of a very common form of rock called Feldspar.
 
The great bulk of material found on the earth's surface is of a small number of substances that are relatively light in weight and "Float" to the earth's surface. The heavier materials such as metals occupy the earth's core. Of the materials found of the surface of the earth Silica is the most abundant (60% of all material on the earth's surface). The second most abundant is Alumina (15%). These materials are chemically referred to as compounds - Meaning that they are a made of two or more elements that are chemically bonded together. In Nature very few materials exist as pure elements; most have formed chemical bonds with other elements - usually oxygen. Silica, for instance is the mineral (or compound) name for the element Silicon that has combined with the element oxygen. Alumina is the mineral name for the material that results from the bonding of Aluminum and oxygen.
 
Feldspar, from which clay is formed, is the mineral name for a family of compounds that results from a chemical bond between Silica, Alumina, and one of three different metals (Potassium, Sodium or Lithium). This rocky substance occurs in great abundance and it's exposure to air and water causes it to change very slowly over vast periods of time into clay. This weathering process results in water, (a compound of Hydrogen and oxygen) replacing the metal in the Feldspar and changing the Feldspar into a new substance we call clay. The chemical formula for pure clay (mineral name Kaolinite) is Al2O3 2SiO2 2H2O.
Kaolinite is the primary ingredient in Kaolin
 
Eating Dirt: It Might Be                                 October 3, 2005
Good for You
Experts Claim the Habit of Eating Clay
May Be Beneficial for Pregnant Women
It melts in your mouth like chocolate, says Ruth Anne T. Joiner, describing her favorite treat.

"The good stuff is real smooth," she adds. "It's just like a piece of candy."

Joiner is describing the delectable taste of dirt -- specifically, clay from the region around her
home in Montezuma, Ga.

While most people would recoil at the thought of eating mud or clay, some medical experts
say it may be beneficial, especially for pregnant women.

"Every time I get pregnant, I get a craving -- I have to eat it," says Joiner, 40, who has given
birth to four healthy babies.

"If I could get just one little bitty piece, that would stop the craving," she says. "It has a fresh,
natural-feeling taste, like the rain or something."


The habit of eating clay, mud or dirt is known as geophagy.

Cultures worldwide have practiced geophagy for centuries, from the ancient Greeks to Native
Americans. In most places the habit is limited to women, especially women who are
pregnant or of childbearing age.

The practice is common in sub-Saharan Africa, and many anthropologists believe geophagy
was brought to the United States by African slaves. It is now most commonly found among
African-American women in the rural South.

Though the practice is rarely if ever recommended by medical professionals, some
nutritionists now admit the habit of eating clay may have some real health benefits.

"It is possible that the binding effect of clay would cause it to absorb toxins," said Dr. David L.
Katz, nutrition expert at the Yale School of Medicine and a medical contributor for ABC News.

Clay's ability to absorb plant toxins is well documented. Jared Diamond, professor of
geography and physiology at the David Geffen School of Medicine at UCLA and author of
"Guns, Germs, and Steel: The Fates of Human Societies" has written on clays that are
especially good at binding with plant toxins.

Diamond notes that many traditional cultures cook food like potatoes, acorns and bread in
clay as a way of protecting against the toxic alkaloids and tannic acids that would otherwise
make these foods inedible.

Glycoalkaloids, for example, are commonly found in potatoes and can cause diarrhea,
vomiting and neurological problems in humans. But when South American Indians eat these
potatoes in combination with alkaloid-binding clays, the potatoes are safe to consume,
according to Diamond.

Dirt: The World's First Mineral Supplement
Medical professionals studying geophagy are also considering whether the minerals in
some clays are especially beneficial for pregnant women.

"Mineral supplements are a pretty new phenomenon," said Katz. "Mineral demand goes up
substantially during pregnancy."

"Soil is nature's multi-mineral supply," he added, "and nature favors behaviors that lead to
survival. It may simply be that women who had this craving were more likely to survive and
pass on this tendency to their offspring."

Mineral content in clays vary from region to region, but many contain high levels of calcium,
iron, copper and magnesium. These are essential minerals for the human diet but even
more critical during pregnancy.

Erica Gibson-Staneland, an anthropologist at Rollins College in Winter Park, Fla., has found
that geophagy is more often found in cultures that do not practice dairying. Dairy products like
milk and cheese would provide important dietary calcium -- when these are absent, pregnant
women may seek other sources.

"It's about women lacking nutrients or women in impoverished conditions who don't have
access to health care, adapting," said Gibson-Staneland.

"In Africa, they eat the dirt from termite mounds," she added, noting that the dirt and clays from
termite mounds are rich in minerals.


My Dirt Is Better Than Your Dirt
Because not all clays are created equal, women who eat clay are very particular about which
clays they consume.

"Everywhere that geophagy has been recorded, it's passed down that there's a certain
location where the dirt is tastier or they know it to be cleaner," Gibson-Staneland said.

Joiner, who has eaten clay for over 20 years, refuses to eat certain clays because they
contain sand or have a gritty taste. "Make sure you get the real stuff," she advised. "Some
people just go out locally and get it. The store's chalk is not as good. I could actually taste the
difference."

And most women who practice geophagy get their clays from sources other than the first few
inches of topsoil, which have the most biological activity -- and the most bacteria, parasites
and other pathogens.

"It's mostly subsurface stuff and I think that's probably less likely to be a source of infection,"
said Gerald N. Callahan, immunologist at Colorado State University in Fort Collins.

Callahan believes eating clay may be a way to build up the immune system during
pregnancy. Citing what has been referred to as a "hygiene hypothesis," he noted that children
raised in rural areas, especially on farms, have fewer allergies and autoimmune diseases
than children raised in cities -- some researchers believe exposure to soil and other
environmental impurities is the reason.

"It's possible that the [pregnant] woman would be strengthening her immune system at the
same time she's going to turn antibodies to the child," said Callahan.


Down Home Georgia White Dirt
Another advantage to eating clay during pregnancy may be the calming effect it can have on
the mother's gastrointestinal system, which can succumb to bouts of nausea and morning
sickness.

Clays, especially white clays, are made of kaolin. Indeed, Rolaids, Maalox and other
medicines recommended for nausea and stomach upset are filled with the same antacid
compounds found in white kaolin clays.
