Which Chitosan Is Right for Your Application?

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.

By Industry

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 →

Animal Feed Feed-grade COS and COS-HCl improve FCR, gut health, and immunity in poultry, swine, shrimp, and livestock. Poultry feed | Pig growth | Shrimp immunity

Frequently Asked Questions — Buying Chitosan Online

What is the minimum order quantity (MOQ)? Most products are available as 25g samples, the smallest quantity for testing. Full bulk orders start at 1 kg. Larger pricing tiers start at 100 kg.

Do all products come with a Certificate of Analysis (COA)? Yes. Every product ships with a batch-specific COA detailing DDA, molecular weight, moisture, purity, and microbial limits. All manufacturing is done in an FDA-registered food facility.

What is the difference between shellfish, mushroom, and BSF chitosan? Shellfish chitosan is the traditional marine-derived option — most affordable, widely available. Mushroom (fungal) chitosan is shellfish-free and vegan-compatible, ideal for allergen-sensitive cosmetic and food formulations. Black Soldier Fly (BSF) chitosan is the cleanest, most consistent source ultra-high purity with full batch traceability, preferred for pharmaceutical and biomedical applications.
