Carboxymethyl chitosan is a higher derivative of chitosan obtained by reacting chitin with chloroacetic acid under basic conditions. Compared with chitin, its physical and chemical properties are optimized, with 100% water solubility, film formation and strong heavy metal chelation. This neutral, pure natural and completely non-toxic product has shown superior characteristics in the fields of medical care, pharmaceutical industry and agriculture. At present, it has been applied in many aspects such as advanced cosmetic additives, heavy metal chelating agents, drug sustained release agents and plant growth agents.

Description:
Chitin is a naturally occurring polysaccharide found in the shells of living organisms such as crabs, lobsters, tortoise, shrimps, and insects or it can be generated via fungal fermentation processes. And chitosan is a unique biobased polymer that is a derivative of chitin and forms the exoskeleton of arthropods. It is obtained by partial deacetylation of chitin using a chemical method or by enzymatic hydrolysis. In general, chitin with a degree of deacetylation of 70% or above is considered to be chitosan.
Application:
Chitin and its derivative chitosan are natural biopolymers which are extracted from crabs, prawns, and shrimps. Chitin consists of �²-(1,4)- linked 2-acetamido-2 deoxy-�²-D-glucose which is insoluble in water and hydrophobic in nature.
Chitin is a natural biopolymer, which is biocompatible and biodegradable and useful in many applications like biomedical, electronics, photography, and textiles. The main advantages of chitin and its derivates are the low cost and easily availability. The chitin-based composites like chitin beads, chitin nanofibers, and chitin hydrogels are used in drug delivery and tissue engineering applications. In recent times, chitin and its derivates have gained much importance in the field of electronic applications as sensors and energy storage applications. Chitin nanofiber papers are being used as flexible green electronics in solar cells and organic light-emitting diodes. Aksoy et al. prepared low-cost chitin derivatives with high conductivity, for the construction of Schottky diodes, which are useful for photoelectrical applications. Schauer et al. reported a variation of the piezoelectric effect of the chitin electrospun nanofibers.

Chitosan 90% High Density is made from shrimp and crab shell; it is a biodegradable and biocompatible material that has several unique properties such as biodegradability, and biocompatibility. High-density chitosan has 2-3 times the density (â?¥0.6g/ml) of ordinary chitosan, and its ability to absorb grease is more than 3 times that of ordinary chitosan at the same volume. These properties make it suitable for various applications including biomedical, agricultural, and environmental. In the field of biomedical engineering, chitosan is used in wound healing, drug delivery, tissue engineering and as a coating for medical devices.
