(hydroxypropyl cellulose uses)
A: Hydroxypropyl cellulose (HPC) is commonly used as a binder, thickener, and film-forming agent in pharmaceuticals, cosmetics, and food products. It improves texture and stability in topical gels and oral tablets. Its water-solubility makes it ideal for controlled-release drug formulations.
A: In tablets, HPC acts as a binder to enhance granule cohesion during compression. It also aids in sustained drug release by forming a gel layer when hydrated. Additionally, it improves tablet disintegration and dissolution rates.
A: HPMC offers thermal gelation and is widely used in extended-release tablets and ophthalmic solutions. Unlike HPC, it is less soluble in cold water but forms viscous solutions when heated. Both are used as excipients, but HPMC has broader construction applications (e.g., cement additives).
A: Yes, HPC is used in creams, gels, and ointments for its emulsifying and moisturizing properties. It enhances product spreadability and adhesion to skin. Its non-irritating nature makes it safe for dermatological formulations.
A: HPMC’s lubricating and mucoadhesive properties help retain moisture on the ocular surface. It prolongs contact time between the drug and the eye, improving efficacy. Its biocompatibility minimizes irritation in sensitive formulations.
