Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose,To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics
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 the presence of metal salts or organic electrolytes . However , when the concentration of electrolytes exceeds a certain limit , gelation and precipitation may result .
2.HPMC also has the characteristics of thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film-forming properties, and extensive enzyme resistance, dispersibility, and adhesion.
3 . Film forming :HPMC provides a strong , flexible and transparent film having a good barrier property against oil and grease . In food application , this property is often utilized for water retention and oil adsorption .
4. Water retention :HPMC is a high effective water retention agent . Its pharmaceutical grade product can be widely used in food , cosmetics and many other fields .
5. Solubility: soluble in water and some solvents, such as ethanol/water, propanol/water in appropriate proportions. The aqueous solution has surface activity. High transparency and stable performance. Different specifications of products have different gel temperatures, and solubility changes with viscosity. The lower the viscosity, the greater the solubility. Different specifications of HPMC have certain differences in performance. The dissolution of HPMC in water is not affected by pH.
1.Appearance: white to yellowish powder or granule
2.Viscosity Specification as below
Note: Any other special requirement for the product can be satisfied through the negotiation.
Pharmaceutical aid: HPMC is used as adhesive, solutizer in tablet, film-forming reagents in pharmaceutical coating,delayed-release and controlled-release tablets or capsules, thickener and water-binding agent in liquid formulation, component in eye drop.

【Transportation and Storage】
The product should be kept in the original bag and stored in the dry and clean place far away from the source of heat and not put together with other chemicals .
The direct addition of the product to water causes the formation of lumps . Lumping results from incomplete wetting of the individual powder particles . Only the powder in contact with water dissolves and the formed gelatinous membrane prevents the remaining powder from dissolving , causing a delay in the dissolution time . The following three methods are recommended for dissolution without forming lumps . The most convenient method should be chosen according to the purpose of your application .
