Cas No. :9004-57-3
Quantity: 200Metric Tons Specs:Ethyl Cellulose Price:22 USD Kilograms Payment Method: T/T, L/C, D/P Ethyl Cellulose Character MF: [C6H7O2(OC2H5)3]n CAS No.: 9004-57-3 EINECS No.: 232-674-9 It did not dissolve in water, but soluble in many organic solvents were used as tablets, granules of the adhesive, can increase the hardness of tablets to reduce friability tablets, it can be used as film-forming agent to improve the appearance of tablets, isolated taste, to avoid the failure of water-sensitive drugs to prevent the influx of metamorphic change agents, promoting the safe storage of tablets, but also can be used as reinforcing material for Sustained Release Tablets. Technical specification Comply with USP, EP and CP. Item K grade N grade Ethoxy (WT%) 45.5-46.8 47.5-49.5 Viscosity (mPa.s) (5% solu., 20℃) 4, 5, 7, 10, 20, 50, 70, 100, 150, 200, 300 Loss on drying (%) ≤3.0 Residue on ignition (%) ≤0.4 Chloride (%) <0.1 Heavy metals (ppm) ≤20 Arsenic (ppm) ≤3 Applications Pharmaceuticals Ethyl Cellulose can be used as film former, binder, dispersing agent, stabilizer, water retention agent and controlled release agent in many kinds of medicine. Coating Ethyl Cellulose can make up some printing and coating, the coating films have good glossiness and excellent slickening capability and flexibility. Plastic Ethyl Cellulose can make up the plastic powder which is easy to take shape, improve cold-resistant property and so on. In other industry Ethyl Cellulose is used as temporary coating for fluorescent lamp tube, to raise the viscosity of phosphor and harden the glasses’ surface. In addition, it is used in electricity conductive printing ink which is used in the basement flake in integrated circuit. Dissolving The usually used solvents of Ethyl Cellulose(DS:2.3-2.6) are aromatics and alcohols. The aromatics are benzene, toluene, ethylbenzene and xylene, suitable percent:60%-80%. The alcohols are methanol and ethanol etc. suitable ercent: 20-40%. Ethyl Cellulose is slowly added to the vessel with organic solvent while stirrung, until it is completely wet and dissolved.
