Description

α-1,3-Glucan is a high-purity, linear polysaccharide composed of D-glucose units linked via α-1,3-glycosidic bonds. This unique structural configuration provides exceptional stability and specific functional properties, making it a valuable biopolymer for advanced industrial and research applications. It is particularly sought after by manufacturers and R&D professionals in the pharmaceutical, cosmetic, and material science sectors for its role as a novel excipient, film-forming agent, and immunomodulatory substrate.

Application

• Pharmaceutical Excipient: Used as a stabilizer, binder, or controlled-release matrix in tablet and capsule formulations.
• Vaccine Adjuvant Development: Investigated for its immunostimulatory properties in next-generation vaccine platforms.
• Cosmetic & Personal Care: Functions as a natural film-forming agent, texture enhancer, and moisturizer in creams, lotions, and serums.
• Biomedical Materials: Serves as a base polymer for creating hydrogels, scaffolds, and wound dressings in tissue engineering.
• Food Science Research: Studied as a dietary fiber, prebiotic, or texturizing agent in functional food development.
• Industrial Biopolymer: Utilized in the production of biodegradable films, coatings, and specialty papers.

Quality Control

Our α-1,3-Glucan is produced under a stringent quality management system. Each batch is subjected to comprehensive analytical testing to ensure identity, purity, and consistency. We provide full traceability and support our products with a Certificate of Analysis (COA) detailing key parameters such as assay, moisture content, and microbial limits. Specifications can be aligned with research or cGMP guidelines as required.

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). Keep the container tightly sealed in a dry environment to prevent moisture absorption and caking.
