Description

Carboxymethyl Chitin is a water-soluble, biocompatible derivative of chitin, a natural polysaccharide. This chemical modification significantly enhances its solubility and functionality, making it a valuable biopolymer for advanced material science and biomedical applications. It is particularly sought after by industries focused on sustainable and bioactive materials, including pharmaceuticals, cosmetics, and advanced wound care.

Application

• Biomedical & Pharmaceutical: Used as a functional excipient in drug delivery systems, a matrix for tissue engineering scaffolds, and a component in hemostatic agents and wound dressings.
• Cosmetics & Personal Care: Acts as a high-performance film-forming agent, moisturizer, and viscosity modifier in creams, lotions, and serums.
• Agriculture: Employed as a biodegradable seed coating agent, soil conditioner, and for the controlled release of agrochemicals.
• Food Industry: Functions as a dietary fiber, thickener, stabilizer, and edible film component in functional food products.
• Water Treatment: Utilized as a natural flocculant and chelating agent for the removal of heavy metals and organic pollutants from wastewater.
• Textile & Paper: Serves as a bio-based sizing agent, coating, and finishing material to impart specific functional properties.
