Carboxymethyl Chitosan

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.

Carboxymethyl chitosan is an important water-soluble chitosan derivative, which has many medical effects, such as promoting wound healing, hemostasis, inhibiting scar, analgesic and antibacterial effects. In addition, it is also widely used in chemical industry, environmental protection and health care products.



Carboxymethyl chitosan has good biocompatibility and biodegradability, and is widely used in hydrogels and wound healing biomaterials, and is also widely used in tissue engineering matrix materials; in addition, carboxymethyl chitosan is easy to be processed into nanoparticles, making it more suitable for drug delivery, bioimaging, biosensors and gene therapy; carboxymethyl chitosan also has many applications in green chemistry in recent years. Because of its unique biological properties, carboxymethyl chitosan has a wide range of applications in the fields of biomedicine and pharmaceuticals.
