Hydroxypropyl Chitosan Applications
Hydroxypropyl Chitosan features excellent biological activity, biocompatibility, biodegradability, and immune-enhancing properties, making it suitable for a wide range of fields:
-
Antimicrobial Effect:
The —NH₂ groups in Hydroxypropyl Chitosan can form —NH₃⁺ in acidic solution, which interacts with negatively charged cell walls, altering permeability and thereby inhibiting or killing microbes. -
Wound Healing & Dressings:
It degrades in the body to produce N-acetylglucosamine, which promotes fibroblast proliferation, collagen deposition, and natural hyaluronic acid synthesis, accelerating wound healing. -
Drug Delivery & Adsorption:
Through electrostatic interaction, Hydroxypropyl Chitosan binds with negatively charged proteins or plasmid DNA. Combined with nanoparticle technology, it serves as an effective drug delivery carrier. -
Tissue Engineering:
Crosslinking Hydroxypropyl Chitosan with gelatin and chondroitin sulfate produces a transparent scaffold with enhanced cell compatibility, supporting corneal cell adhesion and proliferation. -
Paper Industry:
Improves tensile strength, folding endurance, and resistance to dry-heat aging, enhancing overall paper durability.
Packaging & Storage
Packaging: Complies with pharmaceutical packaging standards
Available Sizes: 0.1kg/bag, 1kg/bag, 2kg/bag, 10kg/bag/drum, 20kg/bag/drum
Storage: Store in a sealed container, protected from light
With its pharmaceutical-grade quality, proven biological activity, and multifunctional applications, Hydroxypropyl Chitosan is more than just a material—it’s a solution driving progress across healthcare, biotechnology, and sustainable industries.
