Description
What Is Mushroom Chitosan Hydrochloride?
Mushroom Chitosan Hydrochloride (Chitosan HCl) is the hydrochloride salt form of fungal-derived chitosan. It is produced by converting mushroom chitosan into its HCl salt form, which improves aqueous handling compared with native chitosan.
This product is derived from oyster mushroom (Pleurotus ostreatus) fungal chitin, providing a non-shellfish source for formulators and researchers who prefer fungal-origin chitosan.
Key product details:
- CAS Number: 70694-72-3
- Source: Oyster mushroom (Pleurotus ostreatus)
- Degree of Deacetylation (DDA): ≥85%
- Molecular Weight: Low to Medium, grade dependent
- Appearance: Off-white to light cream powder
- COA: Batch-specific documentation available

Why Choose Mushroom Chitosan Hydrochloride Instead of Native Chitosan?
The most important practical difference is aqueous processability.
Native chitosan normally requires acidic conditions for effective dissolution. This can add extra formulation steps when a product needs to be processed in an aqueous system.
Mushroom Chitosan Hydrochloride is supplied as a pre-formed salt, making it easier to incorporate into water-based formulations.
This may be useful for:
- Pharmaceutical formulation research
- Cosmetic emulsions and serums
- Food and nutraceutical research
- Agricultural spray systems
- Water-treatment applications
- Polymer films and coatings
However, Chitosan HCl is not automatically the correct choice for every formulation.
Selection should consider:
- DDA
- Molecular weight
- Viscosity
- Concentration
- pH
- Required polymer behavior
- Intended application

Why Molecular Weight and Viscosity Matter
Molecular weight and viscosity can significantly influence how Chitosan Hydrochloride behaves in a formulation.
Lower molecular weight / lower viscosity grades may be easier to process where lower solution viscosity is preferred.
Medium or higher molecular weight materials may be more suitable where film formation, polymer-network strength, or viscosity is important.
Do not select a grade based only on the words “low” or “high molecular weight.” The correct range depends on the application.
If your formulation requires a specific MW, DDA, or viscosity, contact our technical team before ordering.
Why Mushroom Origin Matters
Mushroom-derived Chitosan Hydrochloride offers a different sourcing pathway from conventional crustacean-derived chitosan.
Potential reasons buyers may consider mushroom origin include:
- Non-shellfish biological source
- Fungal-origin sourcing preference
- Controlled cultivation opportunities
- Vegan/vegetarian positioning where independently verified
- Clean-label formulation preferences
- Alternative supply-chain requirements
Avoid selecting a product based on origin alone.
Final performance still depends on measurable specifications including DDA, molecular weight, viscosity, purity, and formulation conditions.

Key Functional Characteristics
Water-Soluble Chitosan Form
The principal formulation advantage of the hydrochloride salt is improved aqueous handling compared with native chitosan.
Actual solution behavior may still depend on:
- Concentration
- Molecular weight
- DDA
- Viscosity
- pH
- Ionic strength
- Other formulation ingredients

Cationic Polymer Behavior
Chitosan contains amino groups that can carry positive charge in solution. This contributes to interactions with negatively charged surfaces, polymers, particles, and biological materials.
This cationic behavior is one reason chitosan salts are investigated across drug-delivery, coating, flocculation, adsorption, and other technical applications.
Mucoadhesive Research
Chitosan and related salts have been extensively investigated for mucoadhesive systems because of their interaction with negatively charged mucosal surfaces.
This makes Chitosan Hydrochloride relevant to research involving oral, nasal, buccal, ocular, and other delivery routes.
Film and Polymer-Network Formation
Depending on grade and formulation, Chitosan HCl can participate in:
- Films
- Coatings
- Hydrogels
- Particles
- Polyelectrolyte systems
- Other polymer networks
Performance should always be evaluated experimentally for the intended formulation.
