Description

Chitosan Ascorbate is a water-soluble, biocompatible salt formed from chitosan and ascorbic acid (Vitamin C). This compound is valued for combining the film-forming, mucoadhesive, and antimicrobial properties of chitosan with the antioxidant and stabilizing benefits of ascorbic acid. It serves as a multifunctional ingredient for formulators in the cosmetic, nutraceutical, and biomedical industries, offering enhanced stability and bioavailability in advanced delivery systems.

Application

• Cosmetic & Skincare Formulations: Used in anti-aging serums, creams, and masks as a stabilizing agent for Vitamin C and a film-forming moisturizer.
• Nutraceutical & Dietary Supplements: Employed as an excipient or active component in tablets and capsules for its combined antioxidant and potential immune-support properties.
• Wound Care & Biomedical Materials: Incorporated into hydrogels, films, and dressings for its hemostatic, antimicrobial, and tissue-regenerative capabilities.
• Food Preservation & Coatings: Applied as an edible, antioxidant coating to extend the shelf life of fresh produce and meats.
• Pharmaceutical Drug Delivery: Utilized as a carrier matrix in controlled-release systems for enhancing drug solubility and targeted delivery.
• Agricultural Products: Used in seed coatings and foliar sprays to promote plant growth and provide protective benefits.

Quality Control

Our Chitosan Ascorbate is manufactured under a quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) documenting parameters such as assay, degree of deacetylation, and heavy metal content is available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and potential degradation. For long-term storage, consider using desiccants.
