Hydroxypropyl chitosan is widely used in the biomedical field due to its biocompatibility and biodegradability. It is commonly applied in wound healing as it promotes tissue regeneration and has antimicrobial properties. In drug delivery systems, it serves as a carrier for controlled release of medications, enhancing their stability and efficacy. The chemical is also utilized in cosmetics, particularly in skincare products, for its moisturizing and film-forming abilities. Additionally, it finds applications in agriculture as a seed coating agent to improve germination and plant growth. Its ability to form gels makes it suitable for use in food packaging to extend shelf life by acting as a barrier to moisture and gases.
