    Chitosan Powder CAS 9012-76-4

    Chitosan Powder (CAS 9012-76-4) is a linear polysaccharide functioning as a potent bio-based flocculant in wastewater treatment and an elicitor in agricultural applications. Chemically identified as Poly(D-glucosamine) or Deacetylated chitin, this off-white powder acts to chelate heavy metals and coagulate suspended solids through cationic charge interactions. As a functional Poliglusam biopolymer, it is widely utilized in water purification systems and textile antimicrobial finishing. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific degree of deacetylation (DDA) and viscosity requirements. Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

    Product Description

    Chitosan is a linear polysaccharide produced by the deacetylation of chitin. It appears as an off-white, odorless, semi-transparent, and amorphous solid. It is non-toxic, biodegradable, and possesses cationic properties, which makes it unique among natural polysaccharides.

    Our Chitosan powder is processed through strict quality control to ensure low heavy metal content and precise viscosity ranges. While insoluble in water and organic solvents, it dissolves readily in dilute acids (such as acetic acid or lactic acid) to form a viscous solution. It is widely recognized for its antimicrobial, film-forming, and chelating properties.

    Applications

    1. Food Industry:
      • Preservative: Used as a natural antibacterial and antifungal coating for fruits and vegetables to extend shelf life.
      • Clarifying Agent: Used in fruit juice and winemaking to remove suspended solids.
      • Additive: Acts as a thickener, stabilizer, and texture modifier.
    2. Agriculture:
      • Biopesticide/Fungicide: Boosts plant innate immunity to defend against fungal infections.
      • Soil Amendment: Stimulates beneficial soil microorganisms.
      • Seed Coating: Enhances germination rates and seedling vigor.
    3. Water Treatment:
      • Flocculant: Highly effective in coagulating suspended solids and chelating heavy metals from industrial wastewater due to its cationic nature.
    4. Industrial & Chemical:
      • Used in paper making to improve paper strength.
      • Used in textile printing and dyeing as a binder.

    Storage Conditions

    • Environment: Store in a cool, dry, and well-ventilated area.
    • Protection: Keep away from direct sunlight and moisture. Chitosan is hygroscopic (absorbs moisture).
    • Sealing: Ensure the container is tightly sealed after use to prevent oxidation and moisture absorption.
    • Shelf Life: Typically 24 months when stored properly in original packaging.

    Safety Precautions

    • Allergen Warning: This product is derived from Crustaceans (Shellfish). Persons with shellfish allergies should avoid contact or inhalation.
    • Inhalation: Avoid breathing dust. High concentrations of dust may cause respiratory irritation. Wear a dust mask.
    • Skin & Eyes: Generally non-irritating, but standard safety practice suggests wearing gloves and safety goggles to prevent mechanical irritation.
    • Disposal: Dispose of in accordance with local environmental regulations. The product is biodegradable.
