What Is Chitosan?
Chitosan is a deacetylated chitin polysaccharide commonly supplied as a shellfish-derived powder for supplement raw material sourcing.
Chitosan is a linear polysaccharide made mainly of D-glucosamine and N-acetyl-D-glucosamine units. In commercial supplement sourcing, it is commonly produced by deacetylating chitin from shrimp or crab shells. Since chitosan is a polymeric material, buyers should evaluate degree of deacetylation, viscosity, molecular weight range, source, ash, moisture, particle size, solubility behavior, heavy metals, microbiology, shellfish allergen statement, source declaration, packaging and destination-market label requirements instead of relying on one fixed molecular weight.
Degree of Deacetylation
DDA is one of the most important purchasing specifications because it influences charge density, solubility behavior and application performance.
Viscosity & MW Review
Chitosan is often selected by viscosity and molecular weight range, not by one fixed molecular weight value.
Source Declaration
Shrimp or crab shell source, shellfish allergen status and cross-contact information should be confirmed before label use.
Chitosan Specification Options
Final specifications depend on chitin source, deacetylation process, DDA, viscosity, molecular weight, mesh size, packaging and destination market requirements.

Chitosan vs. Chitin vs. Chitosan HCl
These materials are related, but they are not interchangeable for specification, solubility, label declaration or dosage-form behavior.
| Article | Chitosan | Chitin | Chitosan HCl |
|---|---|---|---|
| Ingredient Identity | Deacetylated chitin; polymer rich in D-glucosamine units | Natural polysaccharide found in crustacean shells and other biological sources | Hydrochloride salt form of chitosan designed for improved water solubility |
| Vérification de l'acheteur | Confirm DDA, viscosity, MW, source, ash, moisture, allergen statement and COA | Confirm source, purity, deproteinization, demineralization and intended processing use | Confirm chloride content, solubility, pH, DDA, viscosity, source and COA |
| Solubilité | Typically soluble in dilute acidic solution, not neutral water | Generally insoluble in water and many common solvents | Designed to be water soluble or more water dispersible depending on grade |
| Notes d'application | Used in capsules, tablets, sachets and powder blends where standard chitosan behavior is acceptable | Usually upstream material rather than direct supplement ingredient in this page context | Reviewed as a separate ingredient when water solubility is required |
Low, Medium & High Viscosity Chitosan
Chitosan buyers often compare grades by DDA, viscosity and molecular weight because these parameters influence processing and finished-product behavior.
| Article | Low Viscosity | Medium Viscosity | High Viscosity |
|---|---|---|---|
| Positioning | Easier mixing and lower solution viscosity in acidic systems | Balanced handling and performance for broad supplement concepts | Higher solution viscosity and stronger polymer behavior in acidic conditions |
| Vérification de l'acheteur | Confirm DDA, low viscosity range, particle size, solubility and COA | Confirm viscosity method, DDA, MW range, density and flowability | Confirm hydration behavior, mixing requirement, viscosity test method and application fit |
| Notes d'application | Often easier for sachets, powder blends and low-viscosity processing needs | Useful when brands need standard chitosan handling and sourcing flexibility | Requires more attention to mixing, dispersion and finished-product texture |
| Examen de la formule | Check flowability, caking, taste and acid solubility behavior | Check blend uniformity, serving size and stability | Check viscosity impact, clumping risk and processing compatibility |
Applications dans le domaine des compléments alimentaires
Gensei supplies Chitosan mainly for dietary supplement raw material projects rather than medical, pharmaceutical, cosmetic, animal feed, water treatment or therapeutic applications.
Remarques sur la formulation à l'intention des marques de compléments alimentaires
Chitosan selection should be aligned with DDA, viscosity, source, dosage format, solubility behavior, shellfish allergen review, packaging and destination-market compliance.
Confirm DDA
Degree of deacetylation should be confirmed by COA because it influences charge, acid solubility and application behavior.
Vérification de la viscosité
Compare viscosity under the same test condition because viscosity depends on concentration, solvent, temperature and method.
Verify Shellfish Source
Shrimp or crab shell source should be reviewed for allergen labeling, cross-contact and destination-market suitability.
Check Solubility Behavior
Standard chitosan dissolves in dilute acidic systems, while Chitosan HCl should be reviewed for water-soluble formulas.
Contrôle de l'humidité
Review loss on drying, caking risk, packaging, storage and production humidity before using chitosan in powders or tablets.
Analyse des informations nutritionnelles
Final ingredient name, amount per serving, source declaration, serving size and Daily Value statement should be confirmed by the brand owner.

Questions fréquemment posées
Questions fréquentes des marques de compléments alimentaires, des fabricants OEM, des fabricants sous contrat et des acheteurs d'ingrédients.
Qu'est-ce que le chitosan ?
Chitosan is a deacetylated chitin polysaccharide made mainly of D-glucosamine and N-acetyl-D-glucosamine units. In supplement raw material sourcing, it is evaluated by source, DDA, viscosity, molecular weight range, particle size, moisture, heavy metals, microbiology and batch COA.
What is the CAS number of Chitosan?
The CAS number commonly used for Chitosan is 9012-76-4. Buyers should confirm identity, source, DDA, viscosity and specification by supplier documents and batch COA.
Is Chitosan a single molecule?
No. Chitosan is a polymeric material, so molecular weight is usually expressed as a range or described by viscosity and degree of polymerization rather than one fixed molecular weight.
What is degree of deacetylation in Chitosan?
Degree of deacetylation, or DDA, describes the percentage of deacetylated glucosamine units in chitosan. It is a key quality parameter because it affects charge density, solubility behavior and application performance.
Is Chitosan water soluble?
Standard Chitosan is generally not soluble in neutral water but is soluble in dilute acidic solutions. Chitosan HCl is a separate water-soluble form and should be reviewed as a different specification.
What is the difference between Chitosan and Chitin?
Chitin is the natural polysaccharide found in crustacean shells and other biological sources. Chitosan is produced by deacetylating chitin, which increases free amino groups and changes solubility and charge behavior.
What is the difference between Chitosan and Chitosan HCl?
Chitosan is the standard deacetylated chitin polymer, while Chitosan HCl is a hydrochloride salt form designed for better water solubility. They should be sourced, specified and labeled separately.
Is Chitosan shellfish derived?
Commercial Chitosan is commonly derived from shrimp or crab shell chitin. Buyers should request source declaration, species information, allergen statement and cross-contact information before label use.
Is Chitosan vegan?
Traditional Chitosan is usually crustacean shell-derived and is not vegan. Fungal or non-crustacean chitosan options should be requested separately and supported by supplier documentation.
Can Chitosan be used in capsules or tablets?
Yes. Chitosan can be evaluated for capsules and tablets when serving size, DDA, viscosity, bulk density, flowability, particle size, compression behavior and stability are suitable.
Can Chitosan be used in drink powders?
Standard Chitosan is not neutral-water soluble, so drink powder concepts should be tested for acid pH compatibility, dispersion, texture, sediment, taste and label positioning. Chitosan HCl may be reviewed when water solubility is required.
Quels indicateurs de qualité faut-il vérifier ?
Buyers should review source, DDA, viscosity, molecular weight range, pH, loss on drying, ash, acid-insoluble matter, particle size, bulk density, heavy metals, microbiology, allergen status and batch COA.
Quels documents puis-je demander avant de passer commande ?
Qualified B2B buyers can request COA, specification sheet, SDS, TDS, source declaration, allergen statement, non-GMO statement, residual chemical report, flow chart, stability information and other technical files depending on the selected grade.
