Chitosan is a biopolymer obtained by deacetylating chitin, which involves removing acetyl groups from the chitin molecule.Amorphous solid, specific spin [α]D11-3° to +10°. Almost insoluble in water, but soluble in organic acids such as formic acid, acetic acid, benzoic acid and naphthenic acid as well as dilute inorganic acids. The industrial product Chemicalbook is a white or off-white translucent flaky solid, slightly pearly. Odourless, non-toxic, easy to degrade, is a rare natural cationic polyelectrolyte. It is a polysaccharide obtained by hydrolysis of strong alkali or enzyme to remove the acetyl group on the sugar base of chitin. Soluble in low acidity aqueous solution, good biocompatibility, non-antigenic, insoluble in human body fluids.
Properties:
Chitosan is the second most abundant biopolymer in nature after cellulose, and is widely distributed, mainly in the shells of many lower animals, especially arthropods such as shrimps, crabs, insects, etc., and also in the cell walls of lower plants, such as mycorrhizal algae and fungi. It is a white or off-white translucent flaky solid, insoluble in water and alkali, but soluble in most dilute acids, including formic, acetic and hydrochloric acids.
Chitosan is the product of removing part of the acetyl group of the natural polysaccharide chitin, with biodegradability, biocompatibility, non-toxicity, bacteriostatic, anticancer, lipid-lowering, immune-enhancing and other physiological functions, widely used in food additives, textiles, agriculture, environmental protection, health care, cosmetics, antimicrobial agents, medical fibres, medical dressings, artificial tissue materials, drug slow-release materials, gene transduction carriers, biological medical fields, medical absorbable materials, medical and drug development and many other fields and other daily-use chemical industries. It is widely used in the fields of food additives, agriculture, environmental protection, beauty care, cosmetics, antimicrobial agents, medical fibres, medical dressings, artificial tissue materials, drug slow-release materials, gene transduction carriers, biomedical applications, medical absorbable materials, tissue engineering carrier materials, medical treatment, drug development and other daily-use chemical industries.
Uses:
1. In the food industry, it is a natural, non-toxic preservative, flocculant, and can adsorb heavy metal ions such as cadmium, mercury and copper in water.
2. As a preservative and thickener.
3. Used as industrial wastewater and municipal wastewater treatment agent, precipitation agent
4. Chitosan is a biocompatible, antibacterial and biodegradable polyelectrolyte with a wide range of biomedical and industrial applications. Its chemical properties and low toxicity can be used as a component of drugs, in gene transfer systems, as a biodegradable membrane and as a skeleton in tissue engineering.
5. Chitosan is non-toxic, odourless, anti-bacterial, and can be used in cosmetics to improve the film-forming property of the product, with anti-bacterial and moisturising functions, without causing any allergic reaction.
