【Characteristics】
HPMC, also known as hypromellose, is one of the non-ionic cellulose mixed ethers. It is a semi-synthetic, inactive, viscoelastic polymer, often used as a lubricant in ophthalmology, or as an excipient or excipient in oral medicine.HPMC is used as a precipitation inhibitor for solid dispersions in spray drying or hot melt extrusion formulations.
Properties
1.Cohesiveness (Binding property) :Hypromellose or HPMC , as a high performance binder , can also be used for molding food and medicine .
2. PH stability :The viscosity of an aqueous solution of HPMC is hardly affected by acid or alkali , and the product can develop an original viscosity in the range of 3 . 0~11 . 0 . Therefore , the solution viscosity tends to keep stable during prolonged storage ..
3. Film forming :Hypromellose or 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 :Hypromellose or 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 Hypromellose or HPMC have certain differences in performance. The dissolution of Hypromellose or HPMC in water is not affected by pH.
6.Hypromellose or 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.

【Application】
Hypromellose (HPMC) is a multi-purpose pharmaceutical excipient.
The high viscosity specification is widely used in the sustained and controlled release system of hydrophilic gel matrix. The low-viscosity grade is used as the main shell material in tablet coating and non-gelatin capsule formulations, and is also a commonly used binder in wet granulation.

【Packaging】
Hypromellose or HPMC is packed in polyethylene bag enclosed in composite fiberboard drum . The standard packing is 25kg/drum
N.W:25KG/drum
G.W:27.5/drum
Loading Quantity in 20'FCL With Pallet: 9Tons
【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.
