Description

Diosmectite CAS NO 110070-78-5 is a purified, naturally occurring aluminosilicate clay belonging to the smectite group, valued for its high specific surface area and excellent adsorption and rheological properties. This material is essential for formulators requiring a safe, effective, and versatile agent for stabilization, gelling, and binding applications. It is primarily utilized by the pharmaceutical, nutraceutical, and personal care industries, where its purity and performance are critical.

Application

• Pharmaceutical Formulations: As an active pharmaceutical ingredient (API) in antidiarrheal medications, where it adsorbs toxins, bacteria, and viruses.
• Gastrointestinal Protectants: Used in products designed to coat and protect the gastrointestinal mucosa.
• Suspending & Gelling Agent: In liquid pharmaceutical suspensions and topical gels to improve stability and texture.
• Excipient & Binder: In tablet formulations to aid in binding powder blends and controlling drug release.
• Nutraceutical & Dietary Supplements: Incorporated into supplements for digestive health and detoxification support.
• Cosmetics & Personal Care: As a thickener, stabilizer, and oil-adsorbing agent in creams, masks, and lotions.
• Veterinary Medicine: For similar antidiarrheal and gastrointestinal protective applications in animal health.

Quality Control

Our Diosmectite is manufactured and tested under a strict quality management system to ensure it meets the high standards required for pharmaceutical and nutraceutical applications. Production adheres to current Good Manufacturing Practices (cGMP). Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, microbiological limits, and physical specifications, ensuring traceability and batch-to-batch consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect flow properties and performance.
