👉 The Bell Fluid, also known as silicone oil or polyethylene glycol (PEG), is a viscous, colorless fluid widely used in various medical and industrial applications due to its unique properties. In medicine, it's primarily employed as a lubricant and emulsifier in ophthalmic solutions, such as contact lens solutions, to ensure smooth eye handling and prevent protein deposition. It also serves as a carrier in drug delivery systems, enhancing the solubility and stability of poorly soluble drugs. Industrially, the Bell Fluid acts as a lubricant, reducing friction and wear in mechanical systems, and is used in the formulation of cosmetics and personal care products for its smooth texture and biocompatibility. Its ability to dissolve a wide range of substances without reacting with them makes it an indispensable fluid in both healthcare and manufacturing.
