Used in pharmaceutical and biomedical applications as a water-soluble polymer for drug delivery systems. Its unique structure enhances stability and controlled release of active ingredients. Commonly found in ophthalmic formulations due to excellent mucoadhesive and lubricating properties. Also employed in coatings for medical devices and tablets, providing sustained release and improved biocompatibility. Useful in tissue engineering scaffolds for its non-toxic, hydrophilic nature that supports cell growth.
