325 Mesh Washed Kaolin for Cosmetic

On the surface, it looks unremarkable. A platy soft white clay mined and processed by Chuangsen in Hebei, kaolin can hide just how versatile and vital it is to a diverse list of industries by appearance alone.First discovered in China, kaolin has been used in the making of porcelain and fine china for centuries. Today, however, kaolin is an important and cost-effective pigment in many paper and paperboard, paints and coatings, plastics, wire and cable and in concrete among many others.What is Kaolin?
Kaolin is derived from the mineral Kaolinite which comes from the Earth's crust. It is an aluminum silicate represented as Al2O3?2SiO2?2H2O. Kaolin was first found in China. The name comes from two Chinese characters that mean "high hill" (Kao-Ling).
Kaolin was formed in the Earth's crust by hydrothermal weathering of feldspar 80 to 100 million years ago.
ChuangSen has high quality secondary kaolin reserves in Hebei that contain high proportions of kaolin and have inherent qualities important for our end applications.
Our reserves are carefully managed to optimally utilize our crudes and manufacture the highest quality finished products.
Uses
Kaolin is a platy white clay that is chemically inert, nonabrasive and possesses a number of characteristics that make it desirable for use in a range of industries, including paper and paperboard, paints and coatings, plastics, wire and cable and in concrete among many others.
