washed Kaolin/ 325mesh washed kaolin

  Kaolin clay (also widely called ”Kaolinite”) is an all-natural ingredient commonly used in many natural cosmetics, soaps, and facial clay masks. Originally it’s from China, that’s why this clay is sometimes referred to as “China clay”.    It is mainly found under the soil of tropical areas. Kaolin clay is prized for its drawing capabilities. It has the ability to draw impurities such as dirt, dead skin cells, residue left behind from the use of other cosmetic products, as well as other toxins without robbing your skin of its natural moisture. Kaolin is also rich in essential and trace minerals that are vital to systems of the human body. These vital minerals are deposited into the skin when Kaolin clay is used topically.      Our Specifications,

    Typical Applications,  Paper Industry, including ensuring the gloss on some grades of paper. in ceramics. It is generally the main component in porcelain. in toothpaste as a light diffusing material in white incandescent light bulbs in cosmetics for its semi-reinforcing properties in rubber in adhesives to modify rheology. the production of common smoking pipes in Europe and Asia in organic farming, as a spray applied to crops to deter insect damage, and in the case of apples, to prevent sun scald. as whitewash in traditional stone masonry homes in Nepal. The most common method is to paint the upper part with white Kaolin clay and the middle with red clay. The red clay may extend to the bottom, or the bottom may be painted black. as a filler in Edison Diamond Discs. as an indicator in radiological dating since Kaolinite can contain very small traces of uranium and thorium. to soothe an upset stomach, similar to the way parrots (and later, humans) in South America originally used it. for facial masks or soap  If any requests,welcome to contact us.Your favorite enquiry will be highly appreciated and replied soon.   Best regards.
