With over 35+ products across 3 origins and 6 derivative types, choosing the right chitosan can be complex. This guide helps you identify the right product for your use case.
Food & Beverage Use food-grade native chitosan or COS for edible coatings, shelf life extension, and natural food preservation. Carboxymethyl chitosan is ideal for spray-application coating systems. Explore food industry applications →
Pharmaceutical & Biomedical For drug delivery systems, wound care, and tissue scaffolds: use pharmaceutical-grade Carboxymethyl Chitosan (CMCS), Trimethyl Chitosan (TMC), or Quaternary Chitosan. All available with COA and batch traceability.
Cosmetics & Personal Care COS and CMCS are the primary actives for skin care formulations, moisturizers, scalp treatments, and anti-aging serums. Mushroom and BSF sources are shellfish-free and vegan-compatible. Read the cosmetics application guide →
Agriculture Chitosan oligosaccharide (COS) agricultural grades trigger plant immunity, improve germination, and extend post-harvest shelf life. Seed coating and crop protection applications. Full agriculture guide →
Water Treatment Native chitosan and CMCS are highly effective flocculants for heavy metal removal, dye removal, PFAS removal, and municipal wastewater treatment. Full water treatment guide →

Most suppliers sell generic chitosan from undifferentiated sources with no traceability. We built something different.
FDA-Registered Manufacturing Facility All products are manufactured in an FDA-registered food facility. Every batch is trackable from raw material through finished goods.
Batch-Specific COA on Every Order No guessing. Every shipment ships with a Certificate of Analysis showing degree of deacetylation (DDA), molecular weight, moisture, purity, and microbial limits.
Three Clean Origins — Shellfish, Mushroom, BSF We are one of the only suppliers offering the same derivative type (e.g., carboxymethyl chitosan) in all three origin variants — allowing direct sourcing comparison for your formulation.
Samples Available from $26 Test before you commit to bulk. Most products available in 25g or 100g sample sizes with free or low-cost shipping.
Industrial Bulk Capability From 1 kg to ton-scale. Pricing tiers at 100 kg, 500 kg, and 1 ton+. Full wholesale pricing available at our wholesale pricing page.
