Description

Chitosan Glutamate is a water-soluble derivative of chitosan, a natural biopolymer derived from chitin. This compound is valued for its enhanced solubility and biocompatibility, making it a versatile functional ingredient. It is primarily utilized in the pharmaceutical, cosmetic, and nutraceutical industries for applications requiring film-forming, mucoadhesive, or delivery-enhancing properties.

Application

• Pharmaceutical Excipient: Used as a film-forming agent in tablet coatings and as a mucoadhesive polymer in controlled-release drug delivery systems.
• Cosmetic Formulations: Serves as a natural conditioning agent and viscosity modifier in hair care and skin care products.
• Nutraceutical Encapsulation: Employed in the microencapsulation of active ingredients for dietary supplements to improve stability and bioavailability.
• Wound Healing: Utilized in advanced wound dressings and hemostatic agents due to its biocompatibility and film-forming ability.
• Biomedical Research: Acts as a substrate or carrier in tissue engineering scaffolds and cell culture applications.
• Agricultural Technology: Used in seed coatings and as a biodegradable carrier for the controlled release of agrochemicals.

Quality Control

Our Chitosan Glutamate is produced under strict quality management systems. Each batch undergoes rigorous testing to ensure it meets specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as degree of deacetylation, viscosity, and residual solvent levels are available upon request. We can support compliance with relevant standards for pharmaceutical (USP/EP), cosmetic, and food-grade applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a low-humidity environment to prevent caking and degradation.
