Chitosan Powder Product Description
Product Overview
Chitosan Powder is a natural linear polysaccharide derived from the alkaline deacetylation of chitin, a structural component found in crustacean shells (e.g., shrimp, crab), insect exoskeletons, and fungal cell walls. Composed of randomly distributed β-(1→4)-linked D-glucosamine and N-acetyl-D-glucosamine units, it is biodegradable, biocompatible, and exhibits low toxicity, making it a versatile biomaterial certified as “Generally Recognized as Safe (GRAS)” by the U.S. FDA .
Key Features
- High Purity & Customizable Specifications:
- Deacetylation Degree: ≥75%, ≥85%, or ≥90% (adjustable for industrial or pharmaceutical needs) .
- Viscosity: Ranges from 10–200 mPa·s to ≥800 mPa·s (tested at 1% concentration, 20°C) .
- pH Stability: 5.0–8.5 (soluble in dilute organic acids like acetic acid) .
- Low Heavy Metals & Microorganisms:
- Heavy Metals: ≤10 ppm
- Arsenic: ≤1 ppm
- Total Aerobic Microbial Count: ≤1000–2000 CFU/g (meets industrial and food-grade standards) .
- Functional Properties:
- Cationic Charge: Binds to negatively charged particles, enhancing flocculation in wastewater treatment .
- Fat Adsorption: Captures up to 12× its weight in lipids, aiding in weight management supplements .
- Dietary Fiber Benefits: Promotes gut health by adsorbing toxins, lowering cholesterol, and regulating blood pressure .
Applications
- Wastewater Treatment:
- Removes suspended solids, heavy metals (e.g., Pb²⁺, Cd²⁺), and reduces COD/BOD levels in textile, mining, and dyeing industries .
- Agriculture & Biostimulants:
- Seed Coating/Foliar Spray: Enhances germination rates (e.g., +15% in cucumber seeds), drought resistance, and crop yield (+8.42% in maize) .
- Natural Pesticide: Suppresses fungal/bacterial pathogens (e.g., tobacco mosaic virus, tomato wilt) .
- Food & Health Supplements:
- Dietary Fiber: Added to baked goods or capsules for cholesterol reduction and digestive health .
- Fat-Binding Agent: Used in weight-loss formulations (e.g., 275 mg capsules, 4–6 tablets/day) .
- Biomedical & Pharmaceuticals:
- Drug Delivery: Improves oral absorption of poorly soluble drugs .
- Wound Healing: Hemostatic and antimicrobial properties support medical dressings .
- Industrial Uses:
- Paper Strengthening: Acts as a sizing agent and retention aid in pulp processing .
- Oilfield Chemicals: Enhances shale gas extraction efficiency as a viscosifier .
