HPMC's structure consists of three essential components the cellulose backbone, methyl groups, and hydroxypropyl groups. This arrangement results in a remarkable hydrophilic and hydrophobic balance, imparting HPMC with high solubility in cold water while remaining inert to several organic solvents. The degree of substitution and molecular weight primarily influence its solubility, viscosity, and gelation properties, making it indispensable in various applications. In the pharmaceutical sector, HPMC is revered for its role as a binder, film-former, and controlled-release agent in tablet formulations. Its robust film-forming ability originates from its unique chemical structure, providing excellent moisture barrier qualities and ensuring drug stability and efficacy over prolonged periods. Moreover, HPMC's versatile viscosity profiles are pivotal for developing coatings and as a vehicle for ophthalmic solutions, underscoring its significance as a multifunctional excipient.
