High Purity (HP) excipients meet global pharmacopeial standards and typically offer tighter impurity control than standard grades, making them a reliable choice for a wide range of pharmaceutical formulations, including biologics.
Super Refined™ excipients go one step further. They undergo Croda Pharma’s proprietary purification process to reduce even trace oxidative impurities—such as peroxides, aldehydes, and catalyst residues—that can compromise drug stability, safety, and shelf life.
In addition, Super Refined™ excipients offer several features not included with HP products, including:
- Enhanced Certificate of Analysis (CoA) information with microbial, endotoxin, and advanced impurity testing for select products
- Undergoes additional purification using proprietary Super Refined™ technology.
Together, both ranges provide premium, pharmaceutically elegant solutions—giving drug developers the flexibility to choose what works best for their molecule and development strategy.
