Description

o-(Carboxymethyl)Chitin is a chemically modified derivative of chitin, a natural biopolymer, where carboxymethyl groups are introduced at the hydroxyl position. This modification significantly enhances its water solubility and bioactivity, making it a highly versatile functional material. It is particularly valuable in the pharmaceutical, biomedical, and cosmetic industries for applications requiring biocompatibility, biodegradability, and controlled release properties.

Application

• Pharmaceutical Excipient: Used as a binder, disintegrant, and controlled-release matrix in tablet and capsule formulations.
• Wound Healing & Tissue Engineering: Serves as a component in hydrogels, films, and scaffolds for drug delivery and promoting tissue regeneration.
• Cosmetic Formulations: Functions as a film-forming agent, moisturizer, and viscosity modifier in creams, lotions, and serums.
• Biomedical Research: Employed as a substrate for cell culture and in the study of enzyme interactions due to its modified polysaccharide structure.
• Water Treatment: Acts as a biodegradable flocculant or chelating agent for the removal of heavy metals and organic contaminants.
• Food Industry (Potential): Investigated for use as an edible coating or a functional dietary fiber supplement.

Quality Control

Our o-(Carboxymethyl)Chitin is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, degree of substitution (DS), viscosity, and molecular weight distribution. Certificates of Analysis (COA) detailing these parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place at 15-25°C. For long-term stability, consider storage under desiccant or in a controlled humidity environment.
