Application of HPMC Phthalate HP55S


KimaCell® HPMC-P HP55S is widely used in the pharmaceutical industry as an enteric coating material, suitable for organic solvent system coating, and has good compatibility with raw materials. Product quality complies with USP-NF/EP/BP. HPMCP is a powder product with an average particle size of 400-600 μm, and the particles can be easily dissolved in organic solvents. It has good solubility in organic solvents. When a large amount of HPMCP is added to the coating solvent at one time, coagulation will occur, and it takes a long time to completely dissolve HPMCP. When using a mixed solvent such as ethanol/water or ethanol/dichloromethane, first pour the ethanol into the container, stir slowly, and then add all the HPMCP to the ethanol to obtain a balanced dissolution. Then, slowly pour the other solvents into the mixture. Using this method, HPMCP can be prepared rapidly.
