Application
(Hydroxypropyl cellulose, HPC) is a non-ionic water-soluble cellulose ether, which is prepared by alkalizing cellulose and reaction with propylene oxide. It has both water solubility and organic solubility, and has good film-forming, adhesion, thickening and surface activity, and is widely used in medicine, food, cosmetics and industrial fields.
