Chitosan Powder VS Other types
| Product Name | Key Modifying Group | Key Benefits | Application Directions |
|---|---|---|---|
| Chitosan Powder | Base Polymer (N-acetylglucosamine & glucosamine copolymers) | A natural cationic polysaccharide with excellent biocompatibility and biodegradability. Offers broad-spectrum antimicrobial activity, adsorption capacity, and film-forming properties. |
|
| Chitosan Hydrochloride Powder | Hydrochloride Salt Group (-HCl) | Retains core benefits of chitosan with significantly enhanced water solubility (especially in neutral conditions). Maintains good biocompatibility and antimicrobial properties. |
|
| Hydroxypropyl Chitosan Powder | Hydroxypropyl Group (-CH₂CHOHCH₃) | Superior water solubility and exceptional moisturizing/humectant properties. Also exhibits antioxidant activity and can promote skin repair. |
|
| Carboxymethyl Chitosan Powder | Carboxymethyl Group (-CH₂COOH) | A water-soluble, amphoteric polymer. Key strengths include promoting wound healing, reducing scar formation, and providing hemostatic and analgesic effects. |
|
| Quaternary Chitosan Powder | Quaternary Ammonium Group (Permanent positive charge) | Possesses the strongest and most stable cationic charge (antimicrobial activity), independent of pH. Offers excellent water solubility, hemostatic, antiviral, and ion-conductive bioactivities. |

FAQ
Q: Chitosan vs. Chitin – which to choose?
A: Chitosan (deacetylated chitin) is soluble in weak acids – ideal for biomedical/nutraceutical uses. Chitin is insoluble, suited for scaffolds/filters⁵.
Q: How to improve water solubility?
A: Use chitosan hydrochloride or carboxymethyl chitosan derivatives. For standard chitosan, dissolve in 1% acetic acid.
Q: Weight management dosage?
A: 1.5-3g/day before meals – binds fat in the GI tract².
