Instantly Dissolves In Cold Water Pharmaceutical Grade High Purity Hydroxypropyl Cellulose
H-HPC (highly substituted hydroxypropyl cellulose) is a nonionic, water-soluble cellulose pharmaceutical excipient. Due to its film-forming properties, adhesiveness, thermoplasticity, water solubility, and organic solvent solubility, it has wide applications in pharmaceutical formulations. Its core uses include tablet manufacturing, sustained-release and controlled-release formulations, mucosal adhesion delivery, solubilization and stabilization, and the development of novel formulations. It can improve the stability, bioavailability, and patient compliance of formulations.
Product Introduction
Highly substituted hydroxypropyl cellulose (H-HPC) is a nonionic cellulose. It appears as white or slightly yellowish-gray granules or fibrous powder, is odorless and tasteless, flammable, and thermoplastic.It is soluble in cold water and polar organic solvents such as ethanol. When its aqueous solution is heated to 40-45℃, a cloud point appears and a precipitate forms.
Application scenarios:
- Binders: Hydroxypropyl cellulose sed in wet or dry granulation of tablets and granules. It can significantly improve particle flowability, compressibility and tablet hardness, reduce the risk of tablet cracking and loosening, while ensuring disintegration and dissolution performance, and is especially suitable for tablet preparation of poorly soluble s.
- Film coating materials: The film is tough and elastic, forming a smooth, wear-resistant coating film that can mask odors, prevent moisture and light, protect the active ingredients of the , control the release rate, and improve the appearance of the tablet to enhance patient acceptance.
- Disintegrants and hydrophilic matrix materials: As disintegrants, they can promote the rapid disintegration of tablets in the body and accelerate dissolution; as hydrophilic matrix materials, they are used to prepare sustained-release tablets, sustained-release pellets, etc., and control the release rate by forming a gel barrier to achieve long-acting administration and reduce the frequency of administration.
- Other formulation applications: Hydroxypropyl cellulose can be used as a base for ointments and gels, providing suitable viscosity and spreadability, enhancing adhesion to the skin, and meeting the formulation needs of topical anti-inflammatory and analgesic s.
Application advantages:
- Hydroxypropyl cellulose is soluble in water and a variety of organic solvents, making it easy to prepare multiple dosage forms and complex formulations; it has excellent film-forming and bonding properties, good thermoplasticity, and is suitable for various processes such as coating and hot melt extrusion.
- High biocompatibility and safety: Hydroxypropyl cellulose is derived from natural cellulose, is non-toxic and non-irritating, has excellent biocompatibility, is basically not metabolized in the body, and is mainly excreted in feces, making it well tolerated by patients.
- Significant optimization of formulation performance: Hydroxypropyl cellulose can balance formulation stability and release performance, improve tablet hardness and coating film protection, and achieve sustained and controlled release and targeted delivery through matrix, adhesion and other effects, thereby optimizing the clinical efficacy of s.
