Description

Magnesium Aluminum Silicate is a refined, naturally occurring inorganic compound widely valued for its unique colloidal and rheological properties. This versatile material serves as a critical functional additive, providing superior suspension, thickening, and stabilization in a wide range of industrial formulations. Key industries that rely on its performance include pharmaceuticals, cosmetics, food, and industrial coatings, where consistent quality and reliable supply are paramount.

Application

• Pharmaceuticals: Used as a suspending, thickening, and stabilizing agent in oral and topical suspensions, lotions, and creams.
• Cosmetics & Personal Care: Functions as a viscosity modifier, emulsion stabilizer, and suspending agent in lotions, creams, toothpaste, and deodorants.
• Food Industry: Employed as an anti-caking agent, carrier, and stabilizer in powdered food products and certain processed foods.
• Paints & Coatings: Acts as a rheology modifier and suspending aid to prevent pigment settling and control application properties.
• Ceramics & Refractories: Serves as a binder and plasticizer in the formulation of ceramic bodies and refractory materials.
• Adhesives & Sealants: Used to modify viscosity and improve the suspension of fillers.

Quality Control

Our Magnesium Aluminum Silicate is manufactured and tested under a strict quality management system to ensure batch-to-batch consistency and performance. We offer grades compliant with major pharmacopoeial standards, including USP-NF and Ph. Eur., as well as food-grade (FCC) specifications. A comprehensive Certificate of Analysis (COA), detailing parameters such as identification, assay, viscosity, pH, and loss on drying, is provided with each shipment to guarantee it meets your precise application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent caking or degradation due to moisture absorption.
