【Characteristics】

Hypromellose or Pharma Grade HPMC Hydroxypropyl Methyl Cellulose with Perfect Thickening, Binding PropertiesHydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose.This product is white or almost white fibrous or granular powder; odorless, this product is almost insoluble in absolute ethanol, ether, and acetone; it swells into a clear or slightly turbid colloidal solution in cold water

Properties

1.Cohesiveness (Binding property) :Hypromellose , as a high performance binder , can also be used for molding food and medicine .

2.Hypromellose 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 :Hypromellose 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 :Hypromellose 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 Hypromellose have certain differences in performance. The dissolution of Hypromellose in water is not affected by pH.

【Technical requirements】

1. Appearance: white to yellowish powder 

2. Viscosity Specification as below

3.Techinical Specifications:

Note: Any other special requirement for the product can be satisfied through the negotiation.

【Application】

Pharmaceutical aid: Hypromellose 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.

Selection guide of products for pharmaceutical:

【Packaging】

Hypromellose, pharma grade HPMC cellulose is packed in 2 layer LDPE bag and sealed in the Drum, it is very safe to store and transport. the standard packing is 25kg/drum, one 20' container could load 9000kg with pallet

【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 .
