*(1)We can supply high-purity chitosan with deacetylation degree >95%.
**(2)The viscosity is determined at 20°C with 1°C chitosan in 1°C acetic acid.
The different applications of chitosan demand different type of chitosan, We can supply it according to the needs. |
| We can provide special molecular weight Chi Chitosan (20,000-300,000) and Chitosan Oligosaccharide (1,000-8,000). |
