Frequently Asked Questions：
Question 1: What is its physical appearance?
A: White powder
Question 2:What are the available grades of Hypromellose Phthalate (HPMCP)?
A: The main commercial grades are HP‑50, HP‑55 and HP‑55S.
Question 3: Regarding Hypromellose Phthalate (HPMCP), what are the respective applications for different grades?
A: The applications with different grades are as below:
| Grade | Viscosity (mPa•s) | Phthalyl Content (%) | Solubility pH | Typical Applications |
| HP‑50 | 44‑66 | 21‑27 | ≥5.0 | Enteric coating, pH‑dependent drug release, controlled‑release matrix |
| HP‑55 | 32‑48 | 27‑35 | ≥5.5 | Enteric coating, capsule coating, controlled‑release formulations |
| HP‑55S | 136‑204 | 27‑35 | ≥5.5 | High‑viscosity enteric coating, controlled‑release matrix |
Question 4: What is its HS‑code for export?
A: 3912900000
Question 5: Is HPMCP the same as regular HPMC?
A: No. HPMC is gastric‑soluble. Modified by phthalation, HPMCP features pH‑responsive enteric performance.
Application 1: What is the main use of HPMCP?
It is mainly used as pharmaceutical enteric‑coating excipient to protect drugs from gastric acid and release in intestine.
Application 2: What is the application difference between HP‑50 and HP‑55?
A: HP‑50 enables early drug release in duodenum; HP‑55 is general‑purpose for standard tablet and capsule enteric coating.
Application 3: What scenarios are suitable for HP‑55S versus HP‑55?
A: HP‑55S has higher viscosity and better film toughness, suitable for fragile tablets to avoid coating cracking.
Application 4：What role does it play in organic synthesis research?
A: 2,2-Dimethylthiopropionamide acts as sulfur‑containing building‑block for new‑methodology laboratory study.
Application 5：Apart from coating, what other uses does HPMCP have?
A: It can act as solid dispersion carrier to improve solubility of poorly soluble drugs, also used as granulation binder and taste‑masking agent.
