Chitosan Global is a US-based supplier of pharmaceutical, cosmetic, food, agricultural, and industrial-grade chitosan powders and advanced derivatives sourced from shellfish, oyster mushroom, and Black Soldier Fly origins.
Whether you need native chitosan, water-soluble derivatives, or specialty compounds for biomedical research, formulation development, agriculture, food preservation, or environmental applications, our catalog provides multiple grades, origins, and specification options.
Use the shop filters or browse the primary product families below. Each family links to detailed product and technical pages.
High-purity raw chitosan in food, agricultural, cosmetic, pharmaceutical, and industrial grades. Available in shellfish, mushroom, and BSF insect origins with DDA from 70% to 95%+.
Water treatment, agriculture, weight management supplements, edible coatings, wound care, and textile finishing.
Fully water-soluble chitosan derivative with no acid required. Ideal for pharmaceutical drug delivery, wound-healing hydrogels, cosmetic moisturizers, and food-preservation systems.
Cosmetics, pharmaceutical formulations, biomedical R&D, edible coatings, and water treatment.
Low-molecular-weight, fully water-soluble chitosan fragments with high bioavailability. Available in pharmaceutical, food, cosmetic, feed, and agricultural grades.
Dietary supplements, gut health, animal feed, crop biostimulants, and anti-aging cosmetics.
Water-soluble chitosan salt with enhanced bioavailability. Preferred for oral supplement formulations, digestive-health products, and aqueous cosmetic systems.
Dietary supplements, personal care, pharmaceutical oral delivery, and feed additives.
Permanently cationic chitosan designed to retain antimicrobial and binding performance across a broad pH range.
Wound dressings, antimicrobial coatings, oral care, skincare actives, and pharmaceutical mucosal delivery.
Specialty chitosan compounds engineered for high-performance pharmaceutical, biomedical, agricultural, and industrial applications.
Advanced drug delivery, specialty coatings, biomedical research, antimicrobial systems, and formulation development.
With multiple origins, grades, molecular weights, and derivative types available, product selection should begin with the intended end use and required technical performance.
Use food-grade native chitosan or COS for edible coatings, shelf-life extension, and natural food preservation. Carboxymethyl chitosan is suitable for spray-applied coating systems.
For drug delivery systems, wound care, and tissue scaffolds, consider pharmaceutical-grade CMCS, Trimethyl Chitosan, Quaternary Chitosan, and selected water-soluble derivatives.
COS and CMCS are commonly selected for skincare formulations, moisturizers, scalp treatments, and anti-aging systems. Mushroom and BSF options are shellfish-free.
Agricultural COS grades can support seed treatment, plant-defense programs, crop biostimulation, germination, and post-harvest quality management.
Native chitosan and selected derivatives are used in flocculation and adsorption systems for heavy metals, dyes, PFAS, municipal wastewater, and industrial effluents.
Feed-grade COS and COS-HCl are evaluated for gut health, immunity, feed-conversion support, and animal-performance applications in poultry, swine, shrimp, and livestock.

Common questions about samples, order quantities, grades, documentation, shipping, technical support, and product origins.
Many products are available as 25 g samples for testing. Standard commercial orders commonly begin at 1 kg, while larger pricing tiers are available for 100 kg, 500 kg, and ton-scale requirements.
Products are supplied with batch-specific documentation where available, including a Certificate of Analysis showing relevant specifications such as degree of deacetylation, molecular weight, moisture, purity, and microbial limits.
Shellfish chitosan is the traditional marine-derived option. Mushroom chitosan is shellfish-free and vegan-compatible. Black Soldier Fly chitosan is insect-derived and offers controlled sourcing and strong batch traceability.
Available grades include Agricultural, Food, Feed, Cosmetic, Pharmaceutical, and Industrial options. Availability varies by product family, origin, molecular weight, and derivative.
Sample orders may ship within approximately 1–5 business days when stock is available. Bulk lead times vary by product, origin, documentation, quantity, and manufacturing schedule.
