Description

Sodium Carboxymethyl β-Glucan is a water-soluble, chemically modified derivative of β-glucan, a naturally occurring polysaccharide. This modification enhances its stability, solubility, and functionality, making it a valuable ingredient for advanced industrial and commercial applications. It is particularly sought after by manufacturers in the pharmaceutical, cosmetic, and nutraceutical sectors for its unique rheological and bioactive properties.

Application

• Pharmaceutical Formulations: Used as a stabilizer, viscosity enhancer, and controlled-release matrix in tablets, capsules, and topical gels.
• Cosmetics & Personal Care: Functions as a film-forming agent, moisturizer, and texture modifier in creams, lotions, and serums for skin barrier support.
• Nutraceuticals & Functional Foods: Incorporated into dietary supplements and functional beverages for its potential immune-modulating and prebiotic benefits.
• Biomedical Research: Serves as a model compound or excipient in drug delivery system development and immunological studies.
• Industrial Applications: Acts as a bio-based thickener or binder in specialty coatings and other aqueous-based systems.

Quality Control

Our Sodium Carboxymethyl β-Glucan is produced under a strict quality management system. Each batch is tested to ensure consistent purity, substitution degree, and functional performance. A comprehensive Certificate of Analysis (COA) detailing parameters such as assay, viscosity, pH, and residual solvents is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

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