HPMC and CMC are widely used pharmaceutical- and food-grade cellulose derivatives valued for their excellent safety, stability, and functional performance. In pharmaceutical applications, they are commonly used as excipients for tablet binding, film coating, controlled-release formulations, suspending systems, and capsule or oral dosage forms, helping improve product consistency, bioavailability, and shelf stability. In food applications, HPMC and CMC function as effective thickeners, stabilizers, emulsifiers, and texture modifiers, enhancing viscosity, mouthfeel, and structural stability in a wide range of food and beverage products while complying with international food safety standards.
