Description

Veegum is a refined, high-purity magnesium aluminum silicate, a versatile inorganic compound widely recognized for its unique colloidal and rheological properties. This material is essential for creating stable suspensions, controlling viscosity, and providing thixotropic behavior in complex formulations. It serves as a critical functional additive for industries requiring superior product stability and texture control, such as pharmaceuticals, cosmetics, and industrial coatings.

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, antiperspirants, and makeup.
• Paints & Coatings: Acts as a rheology modifier and anti-settling agent to prevent pigment sedimentation and control application properties.
• Ceramics & Adhesives: Serves as a binder and plasticizer to improve green strength and workability in ceramic bodies and adhesive formulations.
• Food Industry: Employed as an anti-caking agent and stabilizer in various food products (where food-grade specifications are met).
• Agriculture: Used in pesticide and herbicide formulations as a suspending agent to ensure uniform application.

Quality Control

Our Veegum is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance. Quality is verified through comprehensive testing, including assays for key mineral content, viscosity profiles, pH, and loss on drying. Certificates of Analysis (COA) are provided with each shipment. We can supply grades compliant with relevant pharmacopeial standards (e.g., USP-NF, Ph. Eur.) for pharmaceutical 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.
