Description

Levan CAS NO 9013-95-0 is a high-molecular-weight, naturally occurring polysaccharide composed predominantly of fructose units linked by β(2→6) bonds. This unique biopolymer is valued for its exceptional biocompatibility, film-forming ability, and prebiotic properties, making it a versatile functional ingredient. It is essential for manufacturers in the pharmaceutical, cosmetic, food technology, and biomedical research sectors seeking natural, high-performance materials.

Application

• Pharmaceutical Excipient: Used as a stabilizer, film-forming agent for tablets, and a carrier for controlled drug delivery systems.
• Cosmetic & Personal Care: Functions as a natural moisturizing agent, thickener, and film-former in skincare, haircare, and hydrogel formulations.
• Food Technology: Serves as a dietary fiber, prebiotic, texturizer, and fat replacer in functional foods and beverages.
• Biomedical Research: Employed in tissue engineering scaffolds, wound dressings, and as a biocompatible hydrogel matrix.
• Industrial Biotechnology: Used in the production of bio-based films, coatings, and as a raw material for chemical synthesis.
• Agricultural Applications: Investigated for use as an elicitor to enhance plant defense and as a component in seed coatings.

Quality Control

Our Levan is produced under a stringent quality management system. Each batch is tested to ensure it meets specifications for critical parameters such as molecular weight distribution, purity, and microbiological limits. Certificates of Analysis (COA) detailing these results are provided to guarantee consistency and traceability for your applications. We support compliance with relevant standards for research, food, and pharmaceutical use.

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). Due to its hygroscopic nature, the container must be kept sealed to prevent moisture absorption, which can affect product performance.
