Please feel free to wholesale bulk pure quaternary chitosan powder for sale here from our factory.

Quaternary chitosan powder, also known as chitosan quaternary ammonium salt or N-(2-hydroxypropyl)-3-trimethylammonium chitosan chloride, is a quaternized derivative of chitosan. It is generated by chemically modifying chitosan with quaternary ammonium compounds, such as glycidyl trimethylammonium chloride, ethylene oxide, and 2-hydroxypropyl trimethylammonium chloride. The resultant QC has a positive charge and a high degree of substitution, which improves its water solubility and cationic properties. The addition of negatively charged groups such as carboxyls can enhance the water solubility of QC; on the other hand, it usually involves molecule degradation.
QC shows significant advantages over native chitosan in terms of antimicrobial, antifungal, and antiviral properties, as well as its drug and gene delivery applications. Moreover, QC exhibits improved physicochemical and biological properties, such as low toxicity, low immunogenicity, and sustained release characteristics. QC can be used as a potent carrier for various therapeutic agents, such as proteins, peptides, and genes, which can effectively enhance their bioavailability and efficacy.

• Enhanced Water Solubility: Excellent water solubility across a wide pH range (acidic to neutral/weakly alkaline), overcoming traditional chitosan limitations. Solubility performance may vary with the degree of substitution; please refer to the batch-specific COA for details.
• ‌Potent Antibacterial Activity: Quaternary ammonium groups disrupt bacterial cell membranes, achieving >90% inhibition against E. coli and S. aureus.
• ‌Biodegradable & Non-Toxic‌: Eco-friendly alternative to synthetic polymers, compliant with green chemistry principles.
• ‌Cationic Charge Density: Strong electrostatic binding for heavy metal chelation and particle flocculation.
• ‌Film-Forming Capability: forms durable, transparent films with good mechanical properties.

• Biomedical Engineering‌

‌Wound Care‌: Demonstrates a significant reduction in infection risk in wound care applications.
‌Drug Delivery: Encapsulates therapeutics for controlled release in cancer treatment.

• Water Treatment‌

‌Flocculation: Effectively removes a high percentage of oils and proteins from industrial wastewater at low dosage.
‌Heavy Metal Adsorption‌: Chelates Cu²⁺/Pb²⁺ ions in electroplating effluents.
