Botanical Essence offers premium Carboxymethyl Chitosan Powder, a versatile and highly functional chitosan derivative widely recognized in the nutraceutical, cosmetic, pharmaceutical, and food preservation industries. As a leading manufacturer and supplier of plant-derived and bio-based raw materials, we are committed to delivering consistent quality, full traceability, and technically supported ingredients for global B2B clients.
Product Overview
Carboxymethyl chitosan is an amphoteric polyelectrolyte produced through carboxymethylation of chitosan. This chemical modification significantly enhances its water solubility while preserving and amplifying its natural bioactive properties. Unlike standard chitosan, which dissolves only in acidic conditions, carboxymethyl chitosan powder is readily soluble in both neutral and alkaline aqueous environments, greatly expanding its formulation flexibility.
With excellent film-forming ability, strong biocompatibility, and notable biological activities, this ingredient has become a preferred choice for product developers seeking multifunctional raw materials. Its proven antibacterial, antioxidant, and moisture-retaining capabilities make it particularly valuable in clean-label food preservation, advanced skincare formulations, medical biomaterials, and health supplement applications.
Key Functions and Bioactivities
Broad-Spectrum Antibacterial and Anti-Infection Properties
Carboxymethyl chitosan powder and its derivatives exhibit potent antimicrobial activity against a wide range of bacteria and fungi. Research consistently shows that lower molecular weight fractions, particularly chitosan hexasaccharide, demonstrate the strongest inhibitory effects, making this material an effective natural preservative and protective agent.
Lipid-Lowering and Cardiovascular Support
Studies indicate that carboxymethyl chitosan can help regulate lipid metabolism and shows promise in the prevention and management of arteriosclerosis, supporting its use in functional foods and dietary supplements targeting heart health.
Antiviral Activity
Sulfated derivatives of chitosan have demonstrated antiviral properties in multiple independent studies, expanding the potential application of modified chitosan in immune-supporting and antiviral formulations.
Antitumor Potential
Small-molecule chitosan fractions, especially hexasaccharide forms, have shown excellent anti-tumor activity in various preclinical models, positioning carboxymethyl chitosan as a valuable bioactive ingredient for further research and specialized nutraceutical development.
Primary Applications
- Food Preservation: Extends shelf life through effective microbial control and moisture regulation.
- Cosmetics & Personal Care: Used in moisturizing creams, serums, hair care products, and masks due to its excellent film-forming and skin-conditioning properties.
- Pharmaceuticals & Medical Devices: Serves as a biocompatible material for drug delivery systems, wound dressings, and hemostatic products.
- Dietary Supplements: Applied in functional health products targeting immunity, lipid metabolism, and gut health.
- Agricultural & Environmental Uses: Utilized in biodegradable films and plant protection formulations.
Its superior compatibility with other hydrocolloids, peptides, and active ingredients makes it an ideal choice for complex formulation development.
