Description

Methylglycol Chitosan is a chemically modified derivative of chitosan, where glycol groups are introduced onto the chitosan backbone to enhance its solubility and functionality. This modification is critical for improving the polymer's performance in advanced biomedical and cosmetic formulations where biocompatibility and specific rheological properties are required. It is an essential material for R&D and production teams in the pharmaceutical, biomedical engineering, and high-end personal care industries seeking innovative polymer solutions.

Application

• Drug Delivery Systems: As a functional excipient for creating controlled-release nanoparticles, microspheres, and hydrogel matrices.
• Tissue Engineering Scaffolds: Used to fabricate biocompatible and biodegradable scaffolds that support cell growth and tissue regeneration.
• Wound Healing Dressings: Incorporated into advanced wound care products for its film-forming, moisturizing, and potential bioactive properties.
• Cosmetic Formulations: Serves as a high-performance film-forming agent, moisturizer, and viscosity modifier in serums, masks, and creams.
• Gene Transfection: Investigated as a non-viral vector for the delivery of genetic material in research applications.
• Contact Lenses & Ophthalmic Products: Utilized in the development of biocompatible coatings and materials for ocular applications.

Quality Control

Our Methylglycol Chitosan is produced under a strict quality management system. Each batch is tested to ensure it meets precise specifications for degree of substitution, viscosity, purity, and residual solvents, relevant for pharmaceutical and cosmetic R&D. A comprehensive Certificate of Analysis (COA) documenting identity, assay, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent moisture absorption and caking.
