Main application of JNProperity brand hydroxypropyl methylcellulose phthalate products are used in vegetable capsules
product | specifications | Reference dosage | merit | |
Hydroxypropyl methyl cellulose phthalate | tablet | HP55 | 6%-10% | 1.itself has plasticity, good film formation, no or less plasticizer, can improve the appearance of the tablet and improve the strength of the tablet, can also be used with a small amount of ellac (80:20) to enhance the resistance to gastric juice. 2. Lower dissolved PH value than acrylic resin (PH 50-55), fast drug dissolution and high bioavailability. 3. HPMCP has good storage stability, does not deteriorate for 3-4 years under storage conditions, and its impact on the release of drugs and absorption is less than that of acrylic resin. 4. HPMCP is used as enteric soluble film material, which is better than cellulose phthalate acetate, and does not contain acetate group in the chemical structure, during storage. Does not release acetic acid like CAP |
