In the pharmaceutical industry, different grades of HPMC play pivotal roles in drug formulation. The selection of HPMC grade can influence drug release profiles, stability, and bioavailability. For instance, sustained-release formulations often utilize high-viscosity HPMC grades, which provide a controlled release of the active pharmaceutical ingredient (API) over an extended period. Conversely, immediate-release formulations may use lower viscosity grades to ensure that the drug is released rapidly upon ingestion.

HPMC possesses excellent film-forming capabilities, allowing it to create flexible and transparent films upon evaporation of the solvent. This property is valuable in coating applications, whether for tablets in the pharmaceutical industry or for food products requiring protective layers. Moreover, HPMC can form gels under certain conditions, making it useful in food and cosmetic products as a thickening agent and stabilizer.

Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose, a natural polymer obtained from the cell walls of plants.
