Description

n-Hexanoylchitosan is a chemically modified derivative of chitosan, where hexanoyl groups are introduced to enhance its solubility and functionality. This modification is critical for expanding its utility in advanced biomedical and cosmetic formulations where the native polymer's limitations are a barrier. It is particularly valuable for researchers and manufacturers in the pharmaceutical, cosmetic, and biomaterials sectors seeking improved biocompatibility and tailored material properties.

Application

• Biomedical Engineering: As a functional biopolymer for creating drug delivery systems, wound dressings, and tissue engineering scaffolds due to its improved solubility and biocompatibility.
• Cosmetic Formulations: Used in skincare products as a film-forming agent, moisturizer, or carrier for active ingredients, leveraging its enhanced skin adhesion and hydrating properties.
• Pharmaceutical Excipients: Serves as a matrix for controlled-release tablets or capsules, where its modified solubility profile allows for tailored drug release kinetics.
• Biomaterial Research: A key intermediate for further chemical modifications to develop novel polymers with specific mechanical and biological characteristics.
• Antimicrobial Coatings: Potential application in creating antimicrobial surfaces for medical devices or packaging materials, building on chitosan's inherent bioactivity.

Quality Control

Our n-Hexanoylchitosan is produced under controlled conditions to ensure batch-to-batch consistency. Quality is verified through a series of analytical tests, which may include determination of degree of substitution, viscosity, residual solvent analysis, and microbial limits. A Certificate of Analysis (COA) documenting these parameters is provided with each shipment to guarantee compliance with your specifications and relevant quality guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after opening to prevent moisture uptake and potential degradation.
