CHITOSAN POWDER

Product Name:  Chitosan Powder Source: Shrimp/Crab shell  Application: Food/Cosmetic/Pharma/Industrial Area Solubility: Soluble in acid, insoluble in water Deacetylation degree:85% 90% 95%CAS Number: 9012-76-4 Molecular formula: (C6H11NO4)N     Product description: Chitosan is a linear polysaccharide composed of randomly distributed β-(1-4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). It is made by treating shrimp and other crustacean shells with the alkali sodium hydroxide.   Chitosan has a number of commercial and possible biomedical uses. It can be used in agriculture as a seed treatment and biopesticide, helping plants to fight off fungal infections. In winemaking it can be used as a fining agent, also helping to prevent spoilage. In industry, it can be used in a self-healing polyurethane paint coating. In medicine, it may be useful in bandages to reduce bleeding and as an antibacterial agent; it can also be used to help deliver drugs through the skin.   More controversially, chitosan has been asserted to have use in limiting fat absorption, which would make it useful for dieting, but there is evidence against this.Other uses of chitosan that have been researched include use as a soluble dietary fiber.   Chitosan Specification List Grade Deacetylation/Substitution Degree Food grade 85%, 90%, 95% Medicine Grade 90%, 95% Industrial Grade 80%, 85%, 90% Agricultural Grade 80%, 85%, 90% Water Soluble Chitosan 90%, 95% Carboxymethyl Chitosan 80% Hydroxypropyl Chitosan 80% Chitosan Oligosaccharides 85%, 90%, 95% Chitosan HCL 85%, 90%   Application:   Medicine Grade1.
