Silicone oil in the Medical and Health Care Field: Pharmaceutical Preparations: Silicone oil can be used to prepare drugs such as oral gastrointestinal gas-relieving tablets and pulmonary edema defoaming aerosols. It can also serve as a coating material for controlled-release drug formulations to regulate the rate of drug release. Medical Devices: In medical devices such as catheters and artificial joints, silicone oil can act as a lubricant or a substitute for synovial fluid, reducing friction and wear, and minimizing patient discomfort. Medical Aesthetics: Silicone oil can be used to adjust the viscosity of injectable cosmetic products, or as a post-treatment component for dermabrasion, aiding in the repair of damaged skin.
