Chitosan

Chitosan the unique natural biopolymer is commercially derived from chitin . Although typically manufactured by de-acetylating chitin trough chemical processes. Chitosan is also found in nature, for examples as a key component in fungal cell walls.

Its chemical structure can most simply be described as a co-polymer of glucosamine and acetyl-glucosamine. As a natural cationic biopolymer in its dissolved form (ph<5,7),
Chtitosan possesses a positive charge, giving rise to versatile uses based on tis chlating, anti-microbioal, gelling and film-forming properties. Chitosan consist of a family of products, differing in polymer length, chemical sequences and product purities.
