  • Description Kaolin or china clay is a naturally occurring, almost white, hydrated aluminum silicate. This material does not exhibit a high degree of slip. Kaolin boasts good absorbency, is dense, and is sometimes used to reduce the bulk densities in loose powder products. It provides a matte surface effect, which can slightly reduce sheen left by some talc products.
  • Physical properties Sericite is a mineral similar to white mica in shape and composition. It has a very fine grain size and a silky shine. This material is soft and smooth and has a slippery feel on the skin. Sericite may be coated with silicone and other treatments for enhanced water repellency and skin adhesion.
  • Uses Kaolin has been used:For preparing synthetic turbid water that is employed to evaluate the biosorption capacity of Moringa oleifera leaves.In combination with carrageenan to induce arthritic inflammation in a rat model for evaluating the activity of JAK3 (janus kinase 3) inhibitors.In a study to assess its utility for microparticle-enhanced cultivation (MPEC) of 2-phenylethanol and 6-pentyl-α-pyrone. kaolin (China clay) is a mixture of various aluminum silicates. It is often used in powders and masks given its absorbent, abrasive, bulking, and opacifying properties. This white, soft powder has good coverage and absorption abilities for both water and oil, making it an appropriate absorber of the oil and sweat secreted by the skin. It adheres well to the skin’s surface, yet is easily removed with normal cleansing procedures. Kaolin is considered a non-comedogenic raw material. Adsorbant.
  • Indications Kaolin is a naturally occurring hydrated aluminum silicate that is prepared for medicinal use as a very finely divided powder. The rationale behind its use in acute nonspecific diarrhea stems from its ability to adsorb some of the bacterial toxins that often cause the condition.
Technology Process of Kaolin

There total 2 articles about Kaolin which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:
Guidance literature:
In water; High Pressure; phillipsite and an aq. soln. of AlCl3 is encapsulated in a gold bomb, heating to 300°C at a pressure of 30 MPa for 4 weeks, quenching to room temp.; XRD;
Guidance literature:
In neat (no solvent); byproducts: H2O; heating up to 1050°C; XRD;
upstream raw materials:

aluminium trichloride

Downstream raw materials:

Al0.2N1.8O1.2Si1.8, low temperature

silica gel
