Product type
Hydroxypropyl Cellulose (HPC) is a non-ionic, water-soluble polymer derived from cellulose. It is produced by the chemical modification of cellulose fibers, incorporating hydroxypropyl groups to enhance its solubility and functionality. HPC is commonly used in the pharmaceutical industry as an excipient, particularly as a filler and binder in tablet formulations and as a thickening agent in various dosage forms.
| Appearance | White to off-white powder |
| Solubility | Soluble in water and organic solvents |
| Viscosity | Varies based on concentration and grade |
| Molecular weight | Typically ranges from 50,000 to 1,000,000 Da |
| pH range | 6.0 to 8.0 in a 1% solution |
When selecting Hydroxypropyl Cellulose, buyers should consider the desired viscosity and molecular weight suitable for their specific application. It is also important to specify the required purity levels and any relevant certifications, such as GMP compliance, depending on the intended use. Quantities may vary based on production needs, so clear communication of volume requirements is essential when requesting a quote.
