  3. Chitosan



Chitosan is generated by hydrolyzing chitin which is contained in shells of crab and shrimp.
Chitosan is a biologically originated macromolecular polysaccharide which functions as a natural polycation and has diversity in a variety of practical functions.
KIMICA CHITOSAN is a new high-quality material which has been developed using in-house knowledge of polysaccharide extraction and purification techniques.


Chitosan is a polyglucosamine obtained by deacetylating chitin by hydrolysis.

  • Chitosan, as a solid, is stable to high temperature and strong alkali.
  • Becomes soluble by forming salts with organic acids, such as butyric acid, lactic acid and citric acid, and with hydrochloric acid.
  • The organic acid solution of Chitosan forms a precipitate or a gel in alkali.
  • A Chitosan solution is gelled by forming an anionic polymer colloid and poly ion complex.
  • A Chitosan solution forms a strong membrane on drying.
