Carboxymethyl chitosan is a water-soluble derivative of chitosan, a biopolymer obtained from crustacean shells. Modified by carboxymethylation, this version of chitosan gains enhanced solubility and bioactivity, making it useful in a variety of fields. Known for its biocompatibility, biodegradability, and non-toxicity, carboxymethyl chitosan is widely used in biomedical applications, such as drug delivery and wound healing, as well as in agriculture, cosmetics, and water treatment. Its ability to form gels, retain moisture, and promote cellular repair makes it an ideal ingredient in products where bioactive, water-soluble properties are essential.
