Chitosan Properties  Other names: Poliglusam; Deacetylchitin; Poly-(D)glucosamine; BC; Chitopearl; Chitopharm; Flonac; Kytex CAS Number: 9012-76-4  Molecular formula: (C6H11NO4)N Grade: Medicine/Food/Industrial/Agricultural/ Water Soluble Grade Properties: Offwhite, innocuous, flavorless, amorphous and semitransparent solid, soluble in acid, insoluble in water and alkalis or ordinary organic solvents, decomposed at 185°C. Pingxiang VitalForce Chitosan Oligosaccharide Powder is a linear polysaccharide composed of randomly distributed β-(1-4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). It is made by treating shrimp and other crustacean shells with the alkali sodium hydroxide. Chitosan Oligosaccharide Powder has a number of commercial and possible biomedical uses. It can be used in agriculture as a seed treatment and biopesticide, helping plants to fight off fungal infections. In winemaking it can be used as a fining agent, also helping to prevent spoilage. In industry, it can be used in a self-healing polyurethane paint coating. In medicine, it may be useful in bandages to reduce bleeding and as an antibacterial agent; it can also be used to help deliver drugs through the skin. More controversially, chitosan has been asserted to have use in limiting fat absorption, which would make it useful for dieting, but there is evidence against this. Other uses of chitosan that have been researched include use as a soluble dietary fiber.

Chitasan can be used as preservative for vegetables, meat, seafood, starch, etc. 2 Pharmaceutical use: Promote blood coagulation and wound healing; as drug sustained release matrix; for artificial tissues and organs; improve immunity, prevent high blood pressure, regulate blood sugar, delay aging; as membrane materials, medical materials, etc. 3 Feed additive Chitosan can inhibit and kill harmful bacterial and improve animal immunity 4 In agricultural Chitosan is commonly used as a natural seed treatment and plant growth enhancer. Also it is an eco-friendly bio-pesticide substance, enhance the plant's inherent ability to resist fungal infections. 5 For industrial use: Chitosan has good absorption characteristics of heavy metal ions and is suitable for treatment of organic wastewater, dye wastewater; it is also used in paper industry to improve the wet and dry strength and surface printability of paper.
