Discovered in 1859, Chitosan is a molecule naturally present in shell of crustaceans. This Polysaccharide is composed almost entirely of repeating units of D-Glucosamine and N-acetyl-D-Glucosamine.
The main use of Chitosan is intended for thinness application. Indeed, this polymer has the particularity of having a cationic charge that gives it the ability to bond with lipids.
Another common value concerned joint. Glucosamine, particularly available, has a soothing effect on joint inflammation and pain.
Finally, we appreciate Chitosan for its naturally bacteriostatic and fungistatic properties, thanks to its ionic bonds.
