Chitosan, a natural biopolymer synthesized from chitin through deacetylation, is an unbranched polysaccharide consisting of a (1→4)-2-acetamido-2-deoxy-D-glucose chain, also known as the "sixth essential element for life." It appears as a white, translucent solid with a pearly luster, no special odor, carries a positive charge, and has low solubility in water but can dissolve in weak acids, such as acetic acid.

Biocompatibility and Wound Repair: Chitosan promotes fibroblast proliferation and collagen deposition, accelerating wound healing, and its degradation products are non-toxic and harmless. Its cationic properties interact with the negative charge on cell surfaces, enhancing cell adhesion and tissue regeneration.
Antibacterial and Hemostatic Functions: The amino groups in chitosan molecules disrupt the negative charge balance of bacterial cell membranes, leading to leakage of cell contents and inhibiting various bacteria and fungi. Its gel-like structure can seal vascular wounds and activate platelet aggregation, achieving both physicochemical and hemostasis.
Adsorption and Chelation: The amino and hydroxyl groups on chitosan chains can bind to heavy metal ions, dyes, oils, and other substances, forming stable complexes. Its molecular network structure can adsorb cholesterol, bile acids, and toxins in the intestines through hydrogen bonding and electrostatic interactions.
Film Formation and Sustained-Release Properties: After drying, chitosan solutions form flexible and breathable films that block microorganisms and control moisture evaporation. Its network structure can encapsulate drugs or active ingredients, achieving pH-responsive sustained release, with particularly strong stability in the acidic environment of the stomach.
Pharmaceuticals and Medical Materials: Used as wound dressings, surgical sutures, and hemostatic sponges for the care of burns, ulcers, and other wounds. Developed as a drug carrier for targeted delivery systems (such as gene therapy drugs and anticancer drugs), enhancing efficacy and reducing side effects.
Food Industry and Health Products: Used as a natural preservative in fruit and vegetable preservation coatings, inhibiting microorganisms and regulating respiration. Added to weight-loss supplements, reducing intestinal fat absorption by adsorbing oils. Used for juice clarification and drinking water purification, removing impurities and heavy metals.
Environmental and Agricultural Applications: Developed into a water treatment agent to adsorb heavy metal ions and organic pollutants in industrial wastewater. Used as a biodegradable agricultural mulch film or seed coating agent, improving crop resistance and reducing plastic pollution.
Cosmetics and Daily Necessities: Used in moisturizing masks, shampoos, and other skincare products, forming a breathable moisturizing film and repairing the skin barrier. Used as a toothpaste ingredient to inhibit plaque and bad breath. Developed as an antibacterial textile or hygiene product.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
