Hydroxypropyl Cellulose is a water-soluble polymer known for its excellent thickening and film-forming properties. It exhibits unique thermal gelation behavior, forming gels upon heating, which contributes to its superior sustained-release performance in pharmaceutical applications. It is widely used as a film coating material for tablets, as well as a binder and disintegrant in solid dosage forms. In the food and cosmetic industries, it functions as an effective thickener and stabilizer in various formulations.
