As a pharmaceutical excipient, HPMC has great application value, and it has the advantages that other excipients do not have, so has been widely used in recent years, especially in the pharmaceutical industry. It has great superiority as an excipient. Research and development of it is of great significance to make it applied in wider industries.
Physicochemical Properties of HPMC
HPMC is white powder, tasteless, odorless, non-toxic, completely unchanged in the human body and excreted. The product is soluble in water, and the aqueous solution is colorless, transparent, viscous substance. HPMC has excellent thickening, emulsifying, film forming, dispersion, protective colloids, adhesion, acid and alkali resistance, anti-enzyme and other properties, and is widely used in construction, coatings, pharmaceuticals, food, textile, oilfields, cosmetics, detergents, ceramics, inks and chemical polymerization process. As the renewable awareness of energy and pollution problems of environment have got widespread concern and attention, the applications of natural cellulose and its derivatives have been developed.
HPMC can be used as one of the pharmaceutical excipients with the largest amount at home and abroad currently, for it has many characteristics other excipients do not have.
