Description

Magnesium Aluminometasilicate is a synthetic, high-purity inorganic compound widely used as a multifunctional excipient and adsorbent. Its value lies in its excellent flow properties, high adsorption capacity, and chemical inertness, making it a versatile performance additive. This product is essential for manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries seeking reliable and consistent material performance.

Application

• Pharmaceutical Excipient: Primarily used as a glidant, anti-caking agent, and adsorbent in tablet and capsule formulations to improve powder flow and stability.
• Carrier & Stabilizer: Acts as an inert carrier for active ingredients, flavors, and fragrances in various industrial and consumer product applications.
• Clarifying Agent: Employed in the processing of beverages and oils to adsorb impurities and improve clarity.
• Catalyst Support: Serves as a high-surface-area support material for catalysts in certain chemical synthesis processes.
• Cosmetic Ingredient: Used in powders and makeup products for its oil-absorbing and texture-enhancing properties.
• Desiccant & Moisture Control: Utilized in packaging and certain formulations to control humidity due to its adsorptive characteristics.

Quality Control

Our Magnesium Aluminometasilicate is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for identity, purity, and performance characteristics relevant to its intended use. Certificates of Analysis (COA) are provided with every shipment, and we can support compliance with relevant pharmacopoeial standards (e.g., USP/NF, Ph. Eur., JP) for pharmaceutical grades upon request.

Storage

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