Chitosan Hydrochloride – Marine Origin is a water-soluble derivative of chitin extracted from shrimp and crab shells. With a degree of deacetylation (DAC) ≥90%, it combines the natural bioactivity of chitosan with enhanced solubility, making it easier to incorporate into diverse applications.
Recognized under CAS No. 70694-72-3, this ingredient is also known as Chitosan HCl, Water-Soluble Chitosan, or Chitosan Derivate. It offers excellent biocompatibility, biodegradability, and functionality, serving industries such as cosmetics, agriculture, food, and biomedical applications. Its marine origin provides a cost-effective and eco-friendly solution sourced from renewable crustacean shells.
