Product Description
|
High density chtiosan
|
|
Scientific name: β-1,4-poly-D-glucosamine
Molecular formula : (C6H11NO4)n
CAS No. 9012-76-4
HS No. 2922 5000
Physical characteristic
Off white amorphous translucent flake or powder with pearly color, Insoluble in water or alkali solution, soluble in most organic acid and part inorganic acid like diluted hydrochloric acid and nitric acid etc. In diluted acid solution, backbone chain of chitosan will hydrolyze slowly. There are three crystallographic forms, α, β and γ.
Bulk density of ordinary chitosan is about 0.2-0.4 g/ml, but bulk density of chitosan is about 0.4-0.8 g/ml. Bulk density is higher than ordinary chitosan, and one same capsule can contain more weight chitosan, this is useful in health care field.
Structure:
Raw material
From deep-sea crab shell, such as snow crab shell.
