Chitosan (CAS 9012-76-4) is 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 an alkaline substance, like 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.

Application

Food preservative

In the food industry, chitosan is a natural, non-toxic preservative, flocculant, and can adsorb cadmium, mercury, copper and other heavy metal ions from water;

Agricultural and horticultural use
The agricultural and horticultural uses for chitosan, primarily for plant defense and yield increase, are based on how this glucosamine polymer influences the biochemistry and molecular biology of the plant cell.
Water filtration
Chitosan can also be used in water processing engineering as a part of a filtration process. Chitosan causes the fine sediment particles to bind together, and is subsequently removed with the sediment during sand filtration. It also removes phosphorus, heavy minerals, and oils from the water. Chitosan is an important additive in the filtration process.
Winemaking and fungal source chitosan

Chitosan has a long history for use as a fining agent in winemaking. Fungal source chitosan has shown an increase in settling activity, reduction of oxidized polyphenolics in juice and wine, chelation and removal of copper (post-racking) and control of the spoilage yeast Brettanomyces.

Cosmetic field
Applicable to various cosmetics, such as emollient cream, shower gel, cleaning cream, mousse, advanced ointment frost,

emulsion and colloid cosmetics, etc.

Potential industrial uses

Scientists have developed a polyurethane coating that heals its own scratches when exposed to sunlight. The self-healing coating uses chitosan incorporated into traditional polymer materials, such as those used in coatings on cars to protect paint.
