What's HPMC E15?
HPMC E15 (Hydroxypropyl Methylcellulose 2910, hypromellose E15) is a pharmaceutical-grade cellulose ether used widely in solid dosage forms. It offers reliable binding, film-forming and matrix-forming properties, making it suitable for film coatings, controlled-release matrices and vegetarian capsule shells.
Quick facts:
- CAS: 9004-65-3
- Grade: HPMC 2910 E15 (low–medium viscosity)
- Chemistry: ~28–30% methoxy, ~7–12% hydroxypropyl
- Typical viscosity: ~13–18 mPa·s (apparent viscosity)
Benefits for formulators: improved tablet hardness and appearance, predictable dissolution and sustained-release control, effective film coatings that mask taste and protect APIs. Pharma-grade COA and TDS available on request; please contact us for MOQ and pricing.
