Introduction of CAS:83512-85-0 | Carboxymethyl chitosan
Carboxymethyl chitosan, a water-soluble chitosan derivative, is an amphoteric polyelectrolyte, which is formed by introducing the hydrophilic group -CH2COOH into the chitosan polymer chain. After carboxymethylation modification, chitosan can improve its water-soluble Chemicalbook property, especially its solubility in neutral and alkaline solutions is significantly enhanced. It has the characteristics of film forming, thickening, moisturizing, chelating, etc., so it is widely used in agriculture, medicine, health products, cosmetics, preservation, environmental protection and so on.
