Chitosan Oligosaccharide (COS) is a mixture of oligomers of D-glucosamine, it is the only know positively charged alkaline amino oligosaccharide which derived from rich marine biological resources (shrimp & crab shells) with enzymatic degradation.
Chitosan Oligosaccharide is non-toxic and totally biodegradable and do not leave any residues or affect human body and the beneficial fauna. The Chitosan Oligo Saccharins whose active ingredient is Chitosan oligosacchride agriculture grade have been popular bio fungicides, bio pesticides, plant vaccines and organic fertilizers.
English Name: Chitosan oligosaccharide, Chitosan Oligomers, Chitooligosaccharide, Oligochitosan
Molecular Formula:(C6H11NO4)n（n=2~20）
Structural Formula:
Chitosan Oligosaccharide is the only know alkaline, positively charged, water-soluble, lipophilic, amino oligosaccharide.
