Headcel HPMC for Controlled release formulation skeleton materials
Headcel HPMC for Controlled release formulation skeleton materials is a kind of special hydroxypropyl methylcellulose specially designed to be used as hydrophilic gel framework material.
The hydrophilic gel framework drug release system has many advantages:
1. Wide applicability, no risk of cross-linking reaction, no interaction, high stability
2. The drug release rate is relatively stable, with small individual differences
3. Excellent compressibility, wettability, and other characteristics
