Product Introduction

Polyvinylpyrrolidone, also known as polyvinylpyrrolidone (PVP), is widely used in eye drops due to its beneficial properties. In eye drops, povidone can serve as a lubricant to alleviate dryness and irritation by forming a protective film on the surface of the eyeball. This protective film helps to retain moisture, ensuring that the eyes remain hydrated and comfortable for a long time. In addition, povidone can enhance the viscosity of eye drops, allowing them to better adhere to the surface of the eye and improve drug retention. It can also serve as a stabilizer to ensure the uniform distribution of active ingredients in the solution. The biocompatibility and non irritating properties of povidone make it suitable for sensitive eyes, making it widely used in various ophthalmic formulas for the treatment of dry eye syndrome, irritation, and other eye discomforts.
