Stabilizing agents hydroxypropyl cellulose

Conversions of alkali cellulose with ethylene oxide or propylene oxide, on the other hand, proceed without alkali consumption. The newly formed hydroxyl groups can also add on ethylene oxide or propylene oxide molecules. Commercially produced hydroxypropyl cellulose, with DR = 4, dissolves in water below 38 C. It can be thermoplastically processed and so is used to manufacture water-soluble packaging film, as an adjuvenant in pharmaceutics and confectionery, as a whipped cream stabilizer, as a binder for ceramics, as a suspending agent in emulsion polymerization, etc.
