Due to their different degrees of deacetylation and molecular weights, chitosans are a large group of substances with different properties.
Chitosan differs from chitin in that it has free amino groups and is obtained by deacetylizing chitin. At a minimum deacetylization level of 75 tp 90 % (=amount of free amino groups in the polymer) it is considered to be chitosan. The monomer of chitosan is D-amino glucose.
|Chemical name:||(1,4)-2-Amino-2-desoxy- beta-D-glucan|
Viscosity values refer to 1% chitosan dissolved in 1% acetic acid.
All products are available as flakes with ash contents of <1%, <2%, <3% or as 1-4% solution.
On request chitosan as powder, chitosan derivatives (chitosan HCl, chitosan lactate, etc.), and chitosan oligomers can be produced.
