Organic Chitosan Powder Fertilizer 80 Mesh with 90% Deacetylation Degree for Agriculture and Water Treatment
Chitosan is the second most abundant biopolymer in nature after cellulose, derived from the deacetylation of chitin found in crustacean shells, insect exoskeletons, and fungal cell walls. This white or off-white translucent flaky solid is insoluble in water and alkalis but soluble in most dilute acids.
