Factory Supply Food Grade Water Soluble Carboxymethyl Chitosan Powder CAS 83512-85-0 Medical Chitosan
Introduction
Carboxymethyl chitosan is a water-soluble chitosan derivative and an amphoteric polyelectrolyte. It is formed by introducing a hydrophilic group -CH2COOH into the chitosan polymer chain. The chitosan is treated with carboxymethyl After base modification, the water solubility is improved, especially the solubility in neutral and alkaline solutions is significantly enhanced, making it have film-forming, thickening, moisturizing, chelating and other properties.
Application
Carboxymethyl chitosan (CMC) is a carboxymethylated derivative of chitosan. It is highly polar and easily soluble in water. It has been widely used in agriculture, medicine, health products, cosmetics, preservation, environmental protection, etc. Used as advanced cosmetic additives, heavy metal chelating agents, drug sustained-release agents, plant growth agents, etc.
