China Chitosan Supplier Molecular Structure (C6H11NO4)N
Quantification Chitosan Powder
Description:
Chitosan is recognized as versatile biomaterials and a well-known
organic polymer with well-documented characterization, including
extended non-toxicity, low allergenicity, biocompatibility and
biodegradability, being classified by the US Food and Drug
Administration as a “generally recognized as safe” (Casettari and
Illum, 2014) substance.
Chitosan is a linear polysaccharide composed of randomly
distributed β-(1→4)-linked D-glucosamine (deacetylated unit) and
N-acetyl-D-glucosamine (acetylated unit).
Chitosan, sometimes known as deacetylated chitin, is a natural
polycationic linear polysaccharide derived from partial
deacetylation of chitin. Chitin is the structural element in the
exoskeleton of insects, crustaceans (mainly shrimps and crabs) and
cell walls of fungi (mushroom, aspergillus niger), and the second
most abundant natural polysaccharide after cellulose.

Application Field:
1.Sewage treatment: Chitosan can treat suspended substances in sewage, adsorb certain
heavy metal ions, etc., reduce BOD and COD of sewage, and chitosan
can also be used in surface water treatment.
2.Petroleum Auxiliary: According to the characteristics of chitosan's macromolecule
properties and amino positive charge, chitosan can also be used in
the fields of petroleum exploitation and shale gas exploitation
assistants.
3.Paper making: Special types of chitosan can be used as sizing agent, reinforcing
agent, retention aid, etc. in paper making to increase paper
strength and recover lost pulp.
4.Agriculture: Chitosan can be used in seed soaking, coating agent, foliar spray
fertilizer, bacteriostatic agent, soil conditioner, feed additive,
fruit and vegetable preservative, etc.
5.Chitosan is also widely used in other fields.
Package and Storage:
1.Powder: 25kg/drum.
2. 1-5mm small piece : 10kg/woven bag.
