The Texture Is Soft And Smooth, With Excellent Biocompatibility Used For Eye Drops HPC
Hydroxypropyl cellulose (HPC) is a classic and safe pharmaceutical polymeric excipient used in ophthalmic preparations. With its excellent biocompatibility, rheological regulation capabilities, and film-forming lubricating properties, HPC is widely used in artificial tears, soothing eye drops, and various pharmaceutical eye drop formulations, making it an indispensable high-quality raw material in ophthalmic preparations.
The core functions of HPC in eye drops are viscosity adjustment, moisturizing and lubrication, system stabilization, and sustained-release for eye protection. HPC can precisely regulate the viscosity of the solution, preventing excessively diluted eye drops from rapidly running away, effectively prolonging the adhesion and residence time of the solution on the ocular surface and cornea, achieving long-lasting eye lubrication, and continuously relieving dryness, soreness, foreign body sensation, and eye fatigue caused by prolonged eye use.Compared to ordinary thickening excipients, medical-grade HPC has a purer and more transparent texture. After dissolving, the solution is clear and bright, without flocculent matter. HPC is gentle on the eyes, closely resembling the texture of natural tears, without irritation or blurring, making it suitable for people with delicate ocular surfaces and sensitive eyes. HPC also possesses excellent formulation stability, uniformly dispersing the active ingredients in the medication and preventing sedimentation, precipitation, and stratification, significantly improving the overall stability and storage quality of the eye drops.
HPC formulations are highly compatible, perfectly blending with various ophthalmic excipients such as moisturizers, nutrients, and antibacterial agents. HPC dissolves quickly, is easy to prepare, and maintains system stability, making it a preferred functional excipient for high-end lubricating eye drops, artificial tears, and medical eye care preparations.
- Extended residence time: Adjusts solution viscosity, reduces rapid loss of medication, provides long-lasting lubrication of the ocular surface, and enhances moisture retention and efficacy.
- Superior user experience: Smooth and gentle texture, mimicking the feel of tears, causing no foreign body sensation in the eye, and is mild and low-irritant.
- System stability: Excellent suspending and stabilizing ability, preventing component separation and stratification, ensuring consistent quality even after prolonged storage.
- High biocompatibility: Medical-grade purity, good biocompatibility, non-irritating to the ocular mucosa, suitable for sensitive eyes.
- Sustained-release enhancement: Slowly releases the active ingredient, improving utilization and reducing the frequency of application.
- Strong compatibility: Compatible with various active ingredients and excipients, easy to formulate, and suitable for various ophthalmic formulations.
- Lubrication and repair: Forms a thin moisturizing film on the ocular surface, relieving dryness, soreness, and eye fatigue.
