Description

Aluminium Magnesium Silicate(2:1:2) is a refined, layered silicate clay mineral with a specific 2:1:2 ratio of its core components. This compound is valued for its exceptional rheological properties, acting as a versatile thickener, suspending agent, and stabilizer in complex formulations. It is a critical material for industries requiring precise viscosity control and product stability, such as pharmaceuticals, cosmetics, and advanced ceramics. Its unique structure provides excellent adsorption and ion-exchange capabilities.

Application

• Pharmaceuticals: Used as a suspending and viscosity-increasing agent in liquid oral suspensions, topical creams, and ointments.
• Cosmetics & Personal Care: Functions as a thickener, emulsion stabilizer, and suspending agent in lotions, creams, mascara, and deodorants.
• Paints & Coatings: Acts as a rheology modifier and anti-settling agent to prevent pigment sedimentation and improve application properties.
• Ceramics & Advanced Materials: Serves as a binder and plasticizer in ceramic bodies and as a precursor for synthetic catalysts and molecular sieves.
• Food Industry (where compliant): Employed as an anti-caking agent and clarifier in food processing applications.
• Adhesives & Sealants: Provides thixotropy and controls sag resistance in various adhesive formulations.

Quality Control

Our Aluminium Magnesium Silicate(2:1:2) is manufactured under a strict quality management system. It can be produced to meet various pharmacopeial standards such as USP-NF, Ph. Eur., and JP, as well as food-grade specifications (FCC). Each batch undergoes rigorous testing for parameters like identification, viscosity, pH, loss on drying, and heavy metal content. Certificates of Analysis (COA) are provided and available upon request to ensure full traceability and compliance for your applications.

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 absorption of atmospheric moisture, which can affect performance.
