FAQ

What is Kaolin (CAS: 1332-58-7)?

Kaolin, with the CAS number 1332-58-7, is a naturally occurring aluminosilicate mineral composed of Al2Si2O5(OH)4. It is known for its white, soft, and porous texture, making it a versatile material in various industries. Kaolin is chemically inert, heat-resistant, and has strong adsorption properties, which contribute to its widespread use in pharmaceuticals, cosmetics, and manufacturing.

What are the main uses of Kaolin (CAS: 1332-58-7)?

Kaolin (CAS: 1332-58-7) is primarily used in pharmaceuticals as a binder, absorbent, and anti-caking agent. It also serves in the cosmetics industry for its mildness and absorbency, in the food industry as a clarifying agent, and in industrial applications like paper coating and ceramic production. Additionally, it is utilized in research for its thermal stability and as a component in some topical medications.

Is Kaolin (CAS: 1332-58-7) safe?

Kaolin (CAS: 1332-58-7) is generally considered safe when used as intended. It has low toxicity and is non-irritating to skin and mucous membranes. However, prolonged inhalation of fine particles may cause respiratory issues, so proper handling precautions, such as using gloves and avoiding dust exposure, are recommended. Safety standards ensure its GRAS (Generally Recognized as Safe) status for food applications.

How should Kaolin (CAS: 1332-58-7) be stored?

Kaolin (CAS: 1332-58-7) should be stored in a cool, dry place away from moisture and light to maintain its stability. Use airtight containers to prevent contamination and exposure to air. The optimal storage temperature is 15-25°C, and it should be kept in a well-ventilated area to avoid clumping. Ensure proper labeling and secure storage to prevent accidental ingestion or inhalation.
