Bio21's Chitosan material product specification

The main properties of Chitosan product specifications are following; 

      • Degree of Deacetylation (%DD)
      • Molecular Weight (MW)
      • Viscosity
      • Raw material source (the shells of sea creatures (Crustacea Malacostraca))  Alpha and Beta type Chitosan 

These of %DD, MW, Viscosity , and raw material sources are key factors of the active or main functions of the Chitosan application or the final product


The other significant product properties of Chitosan product specifications are  heavy metals, microbiological factors, Ash content, bulk density / tapped density, solubility, turbidity, and moisture

All properties of Chitosan material product specification combined are identified to the Chitosan grade

      • food grade / dietary supplement grade
      • Medical device grade / Pharma grade
      • Agricultural use (grade)
      • Industrial use (grade)


Bio21 Chitosan material product specs category, which is based for the applications
