Chitosan is a linear polysaccharide. Chitosan is produced commercially by deacetylation of chitin, which is the structural element in the exoskeleton of crustaceans such as crabs, shrimp, etc. It is known to be biocompatible, biodegradable and nontoxic. It improves seed germination, root development and disease resistance. Chitosan Fertilizer is a natural antimicrobial, antibacterial, and antifungal agent, tested and approved by US EPA for use in agriculture & horticulture.
Chitosan is positively charged and soluble in acidic to neutral solution with a charge density dependent on pH and the % DA-value. This makes chitosan a bioadhesive which readily binds to negatively charged surfaces such as dyes, negative ions etc.


Applications Of Chitosan

Due to its unique biological characteristics, including antimicrobial, antifungal, antibacterial, biodegradability and nontoxicity, many applications have been found either alone or blended with other natural polymers (starch, gelatin, alginates) in the food, pharmaceutical, textile, agriculture, water treatment and cosmetics industries.

The amino in Chitosan molecule react with acid and form the high polymer polyelectrolytes that carry positive charge, which through electrostatic interaction with the mass suspended solids in solution, result in the “absorption and bridge effect” that turns tiny particles into large particles for subsidence. This is known as the flocculation technology.
