(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.
Different applications of chitosan demand different type of chitosan, We can supply it according to the needs.
We can provide special molecular weight Chitosan (20,000-300,000) and Chitosan Oligosaccharide (1,000-8,000) |
