Product Description Hydroxypropyl Methyl Cellulose (HPMC)Product DescriptionHydroxypropyl methyl cellulose (HPMC) or hypromellose, is a cellulose-based polymer for film coating, wet granulation, and hard capsule manufacturing. It is practically insoluble in hot water, anhydrous ethanol, and dissolves in cold water, resulting in a colloidal solution.Product Properties1 . Resistance to salting : Hydroxypropyl methyl cellulose (HPMC) is a nonionic cellulose ether and it is not a polyelectrolyte . The aqueous solution of Hydroxypropyl methyl cellulose (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 . Surface activity : An aqueous solution of Hydroxypropyl methyl cellulose (HPMC) has a high surface activity and functions as a protective colloid agent , emulsion stabilizer and dispersant .3 . Thermal gelation :An aqueous solution of Hydroxypropyl methyl cellulose (HPMC) will gel or precipitate when heated to a certain temperature , but it reverts to the original solution state on subsequent cooling . The temperature at which gelation or precipitation occur depends on the type of HPMC , its concentration and the rate of heating .4 . 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 .5. Water retention :Hydroxypropyl methyl cellulose (HPMC) is a high effective water retention agent . Its pharma grade product can be widely used in food, cosmetics and many other fields .6 . Film forming :Hydroxypropyl methyl cellulose (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 .7 . Cohesiveness (Binding property) : Hydroxypropyl methyl cellulose (HPMC) , as a high performance binder, can also be used for molding food and medicine .Technical IndexTable 1Item SpecificationsHPMCFEJKLoss on drying, % 5.0MAXResidue on ignition,%1.5MAXHeavy metals,ppm20MAXPH5.0~8.0Bacterium1000cfu/gram MAXMold100cfu/gram MAXViscosity (2% solution),mPa.srefer to Table 2Table 2LevelSpecific range (mPa.s)LevelSpecific range (mPa.s)54~980006000~90001510~20100009000~120002520~301500012000~180005040~602000018000~3000010080~1204000030000~50000400300~5007500050000~85000800600~90010000085000~13000015001000~2000150000130000~18000040003000~5600200000≥180000*Any other special requirement for the product can be satisfied through the negotiation between Supplier and Buyer.ApplicationHydroxypropyl methyl cellulose (HPMC) is used as adhesive, solutizer in tablet, film-forming reagents in pharma coating,delayed-release and controlled-release tablets or capsules, thickener and water-binding agent in liquid formulation, component in eye drop.
