  Product Characteristics
  1. Appearance: HPMC is a white or whitish fibrillar /granular and odorless powder.
  2. Solubility: HPMC is nearly insoluble in anhydrous ethanol, ethyl ether and acetone. It is swelled in cold water to form a transparent or a slight cloudy solution. HPMC can be dissolved into some organic solvents and also in water-organic solvent mixed solvents.
  3. Fineness(Graininess): The oversize product above 100 mesh should not exceed 5.0%.
  4. With reduction of methoxyl groups content, HPMC is increased in gelling temperature and decreased in water solubility and surface activity.
  Properties
  1. Resistance to salting out: HPMC is a nonionic cellulose ether and it is not a polyelectrolyte. The aqueous solution of HPMC is comparatively stable even in
  2. the presence of metal salts or organic electrolytes. However, when the concentration of electrolytes exceeds a certain limit, gelation and precipitation may result.
  3. Surface activity: An aqueous solution of HPMC has a high surface activity and functions as a protective colloid agent, emulsion stabilizer and dispersant.
