Kaolin Clay
Kaolin is a kind of non-metallic mineral. It is a kind of clay mainly composed of kaolinite group clay minerals including kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals. Because it is white and delicate, it is also called Baiyun soil. The pure kaolin is white, delicate and soft with good plasticity and fire resistance.

Diatomite
Diatomaceous earth is a kind of biogenic siliceous sedimentary rock, mainly composed of ancient diatom remains. Its chemical composition is mainly SiO2, containing a small amount of Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5 and organic matter. The main uses of diatomite are filter aids, fillers, adsorbents, catalytic carriers, environmentally friendly building materials and so on.

Talcum Powder
Talcum powder is made by grinding talc with Raymond mill and other high pressure touch.
Whitness: 85-96%.
Talc has excellent physical and chemical properties: such as lubricity, anti-viscosity, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good luster, strong absorption and so on.

Bentonite
Bentonite clay is a kind of NATURAL clay mineral with montmorillonite as main component, it has property of good cohesiveness, expansibility, adsorption, plasticity, dispersion, lubricity, cation exchange. After exchange with other base, lithium base, it has very strong suspension property. After acidizing it will have excellent decolorizing ability. So it can be made into all kinds of bonding agent, suspending agent, adsorbent, decoloring agent, plasticizer, catalyst, cleaning agent, disinfectant, thickening agent, detergent, washing agent, filler, strengthening agent,et. Its chemical composition is quite stable, so it is crowned as “universal stone”. And Cosmetic Clay grade is just using by bentonite’s whitening, and thickening characters.

Calcium Carbonate
Calcium carbonate is a chemical compound with the formula CaCO3. The thermodynamically stable form of CaCO3 under normal conditions is hexagonal β-CaCO3. Calcite, aragonite and vaterite are pure calcium carbonate minerals. Industrially important source rocks which are predominantly calcium carbonate include limestone, chalk, marble and travertine.
