Chitosan is the general name of chitin and its derivates, which is natural high polymer processed and extracted from shells of invertebrate crustacean living in rivers, lakes or ocean. As per the solubility, they are classified into insoluble chitosan, soluble chitosan and water soluble chitosan.
Insoluble chitosan, commonly known as chitin, scientific name is polyacetylglucosamine. Whose chemical character is stable, not soluble in water, hardly soluble in thin acid, alkali or commonly used solvent, soluble in thick sulphuric acid, hydrochloric acid as well as 85% phosphoric acid,. But after dissolve, molecular weight of chitin is lowered evidently.
Soluble chitosan, generally known as chitosamine, scientific name poly-2-de-2-aminoglucose, also known as chitose, is the key derivates of insoluble chitosan. Not soluble in water, soluble in thin acetic acid and so forth acid solution.
2. Applications
Due to the unique chemical and bioactivity characteristic of its physic-machanism character, chitosan are used in vast fields:
a. Medical and health care usages: Can be used to make operation sewing thread, artificial skin, wound band, immune promoter, anti-tumor and antibiotic drugs etc.
b. Agricultural usages: May be used as biodegradable plastic, insecticides and biological promoters etc.
c. Chemical usages; Used to produce flocculent, seperating film, light-sensive material, waste water absobent, fiber, shampoo, hair fixing agent, moisture conditioning agent etc.
d. Food industry usages: Used as food additives, health care foods, foodstuff packaging etc.
e. Textile usages: Used as textile conditioning agent, color fixing agent, sizing agent etc.
