Description

Carboxy Methyl Pachymaran is a chemically modified polysaccharide derivative, specifically a carboxymethylated form of pachymaran, a β-glucan extracted from *Poria cocos*. This modification enhances its water solubility and introduces functional carboxyl groups, making it a valuable biopolymer for advanced industrial and research applications. Its primary value lies in its ability to act as a versatile thickener, stabilizer, and functional carrier, offering unique rheological and bioactive properties. Key industries that utilize this compound include pharmaceuticals for drug delivery systems, cosmetics as a skin-conditioning agent, and food technology as a dietary fiber and texture modifier.

Application

• Pharmaceutical Excipient: Used as a binder, disintegrant, and controlled-release matrix in tablet and capsule formulations.
• Cosmetic Ingredient: Functions as a film-forming agent, viscosity controller, and moisturizer in creams, lotions, and serums.
• Food Additive: Employed as a dietary fiber supplement, thickener, and stabilizer in functional foods and beverages.
• Biomedical Research: Serves as a hydrogel scaffold material in tissue engineering and wound dressing applications due to its biocompatibility.
• Industrial Applications: Acts as a dispersant, viscosity modifier, and water-retention agent in various specialty chemical formulations.

Quality Control

Our Carboxy Methyl Pachymaran is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency, purity, and performance. Key parameters monitored include degree of substitution, viscosity, pH, and heavy metal content. Certificates of Analysis (COA) detailing all test results are provided with every shipment. We can support compliance requirements for various application 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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
