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. Fineness(Graininess) The oversize product above 100 mesh should not exceed 5.0%. With reduction of methoxyl groups content, HPMC is increased in gelling temperature and decreased in water solubility and surface activity.Purpose of Application HPMC can be functioned as thickener, dispersant, emulsifier, film forming agent, etc. It is used in tablets for dressing and binding to improve solubility of the drugs and reinforce tablets’ water prevention function. HPMC can be directly applied to food not only as emulsifier, binder, thickener or stabilizer, but also as packing material.Package25 kg/drum or bag
