Application

Hydroxypropyl cellulose can be used in the following applications:
  • HPC is soluble in organic solvents which makes it suitable for the preparation of polymer gel electrolytes for electrochemical devices. The network-forming ability of HPC can improve the mechanical and electrical properties of gel electrolytes.
  • Electrospun hydroxypropyl cellulose nanofibres can be used to develop drug delivery systems for a variety of hydrophobic drugs.
  • Hydroxypropylcellulose combined with an effervescent agent like sodium carbonate can be usedas a binder and functional material to prepare floating tablets for thecontrolled release of ofloxacin.

General description

Hydroxypropyl cellulose (HPC) is a neutral polysaccharide prepared by reacting propylene oxide with alkali cellulose at high temperatures and pressure. It is soluble in water and many polar organic solvents. HPC is widely used as a food additive and in drug delivery systems.
