Chitosan
Applications: Chitosan
is a polycationic polymer containing more than 5000 glucosamine
units and is obtained commercially by alkaline deacetylation of chitin
(a N-acetyl-glucosamine polymer) from shellfish exo-skeletons. Chitosan
is inexpensive, non-toxic and possesses potentially reactive amino
functional groups. It has been shown to be of potential use in many
different fields: as an antifungal compound in agriculture, as a flocculating
agent in wastewater treatment, as a food additive in food industry,
as a hydrating agent in cosmetics, and more recently, as a pharmaceutical
agent in biomedicine. It is known to have a marked hypocholesterolemic
effect in cholesterol-fed rats, lowering cholesterol absorption in
the lymphatic thoracic duct.

deacetylation degree *② The viscosity is determined at 20.0℃
with 1%chitosan in 1.0% acetic acid.The application of chitosan is
different with that of quality. We can supply chitosan with differentquality
as required.
