Cellulose, a natural polymer abundantly found in plant cell walls, brings biocompatibility and structural integrity to these composites. Its crystalline structure provides a solid foundation that ensures the physical stability of the tablets or capsules. On the other hand, HPMC, a synthetically modified cellulose derivative, introduces solubility and thermogelation characteristics which are crucial for modulating the release rates of active pharmaceutical ingredients (APIs). When combined, these materials synergize, creating formulations with tunable release profiles and enhanced patient compliance.

Shijiazhuang Yongfeng china cellulose ether

HPMC Ether, also known as Hydroxypropyl Methylcellulose Propionate or HPMC acetophthalate, is synthesized by substituting some of the hydroxyl groups on the HPMC backbone with ether moieties. This modification imparts amphiphilic characteristics to the polymer, allowing it to interact both with water and organic solvents. As a result, HPMC Ether can function as a surfactant, emulsifier, and suspending agent, depending on the formulation's needs.
