Tan Florida Kaolin
Scientific Name(s): Kaolin , hydrated aluminum
Common Name(s): Heavy or light
kaolin , China clay , bolus alba , porcelain clay , white bole , argilla
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.
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
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
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.
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
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
Kaolin has the approximate chemical formula of
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
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.
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.
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 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
