Market Overview

Chitosan is a natural polysaccharide produced through the deacetylation of chitin, which is primarily obtained from the shells of shrimp, crabs, and other crustaceans. It is valued for its biodegradability, biocompatibility, antimicrobial properties, film-forming capabilities, and ability to bind certain contaminants.

The material is widely used in water and wastewater treatment, agriculture, food preservation, pharmaceutical formulations, cosmetics, biotechnology, and biomedical applications. Its ability to support environmentally responsible product development is increasing interest among manufacturers seeking alternatives to selected petroleum-based polymers and conventional treatment chemicals.

Advancements in extraction methods, product purification, and formulation technologies are further improving the commercial potential of chitosan across established and emerging end-use industries.
