Description

Arabinogalactan is a high-molecular-weight, highly branched polysaccharide derived primarily from the Larch tree (Larix species). This natural biopolymer is valued for its excellent solubility, low viscosity, and prebiotic properties, making it a versatile functional ingredient. It serves critical roles in the pharmaceutical, nutraceutical, food, and cosmetic industries as an immune-modulating agent, dietary fiber, stabilizer, and carrier. Our supply of Arabinogalactan CAS NO 9036-66-2 ensures consistent quality and reliable availability for global B2B partners.

Application

• Pharmaceutical Excipients & Drug Delivery: Used as a carrier and stabilizer in tablet formulations and as a biodegradable component in controlled-release systems.
• Nutraceuticals & Dietary Supplements: Employed as a prebiotic fiber to support gut health and as an immune system modulator in supplement capsules and powders.
• Food & Beverage Industry: Functions as a natural emulsifier, stabilizer, and texturizing agent in beverages, dairy products, and low-fat foods.
• Cosmetics & Personal Care: Acts as a natural humectant and film-forming agent in skin care serums, creams, and hair care products for moisture retention.
• Microbiological & Cell Culture Media: Serves as a carbon source and gelling agent in specialized culture media for microbiology and biotechnology research.
• Veterinary and Animal Feed: Incorporated into feed formulations to promote gastrointestinal health and immune function in livestock and companion animals.

Quality Control

Our Arabinogalactan is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets specifications for identity, purity, and microbiological safety. We can supply material compliant with relevant standards for food (FCC) and dietary supplement applications. A comprehensive Certificate of Analysis (COA) detailing assay, heavy metals, residual solvents, and microbial limits is provided with every shipment.

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 after each use to prevent absorption of atmospheric moisture, which can lead to caking and degradation.
