Additionally, it is utilized in the formulation of eye drops to treat dry eye syndrome by promoting corneal hydration and reducing irritation. In cosmetic products, it is incorporated for its moisturizing and skin-soothing properties, enhancing skin elasticity and reducing signs of aging. Its biocompatibility also makes it suitable for use in biomedical applications, such as drug delivery systems and tissue engineering scaffolds.
