    Carboxymethyl chitosan is a water-soluble chitosan derivative, which is an amphoteric polyelectrolyte. It is made by introducing hydrophilic group -CH2COOH into the polymer chain of chitosan. After carboxymethyl modification, the water solubility of chitosan is improved, especially in neutral and alkaline solutions, which makes it have the characteristics of film-forming, thickening, moisturizing and chelating, so it is widely used in agriculture, medicine, health care products, cosmetics, preservation and environmental protection. Carboxymethyl chitosan (CMC) is a carboxymethyl derivative of chitosan, which is highly polar and easily soluble in water, and has been widely used in the fields of pharmacy, biomedical materials development and so on. Because the content of carboxymethyl chitosan in drugs will directly affect its clinical effect of antibacterial and anti-infection, it is particularly important to accurately quantify carboxymethyl chitosan. Used as advanced cosmetic additive, heavy metal chelating agent, drug slow-release agent, plant growth agent, etc.
