Glycol chitosan is widely used in drug delivery systems due to its biocompatibility and ability to enhance the solubility of hydrophobic drugs. It serves as an effective carrier for targeted cancer therapy, improving the stability and bioavailability of therapeutic agents. In wound healing, glycol chitosan promotes tissue regeneration and acts as a protective barrier against infections. It is also utilized in gene delivery, where it helps in the efficient transfection of genetic material into cells. Additionally, glycol chitosan is employed in cosmetics for its moisturizing and film-forming properties, enhancing skin hydration and texture, and in hair care products to improve smoothness and prevent hair loss. Its antimicrobial properties make it suitable for use in food packaging to extend shelf life and prevent microbial contamination.
