Chitin (CAS 1398-61-4) is a high-purity nitrogenous polysaccharide obtained from crustacean shells, supplied as a white purified powder that serves as a renewable raw material for chitosan production and as a non-toxic, biodegradable biopolymer in water treatment, cosmetic and textile applications. It serves as a vital renewable raw material for the industrial synthesis of chitosan and other high-value bioactive derivatives.
As a non-toxic and biodegradable biopolymer, it is widely utilized in both Technical Grade and Cosmetic Grade applications. Its unique chelating properties and inherent biocompatibility make it an indispensable component in modern green chemistry and sustainable manufacturing.
This material acts as an effective thickening agent and film-forming polymer across various industrial sectors. Its ability to provide superior moisture retention and mechanical strength significantly enhances the performance of specialized coatings, functional fibers, and filtration media.
