Dimethylsilicone oil is widely used as a lubricant in various mechanical and industrial applications due to its thermal stability and low viscosity. It is commonly applied in the automotive industry to lubricate rubber parts, such as O-rings and seals, to enhance their flexibility and longevity. In the medical field, it serves as a key component in personal care products like skin creams and lotions, providing a smooth, non-greasy texture and acting as a moisture barrier. Additionally, it is utilized in the manufacturing of cosmetics, such as foundations and hair conditioners, to improve spreadability and shine. In electronics, it is employed as a dielectric fluid to protect components from moisture and heat. Its water-repellent properties also make it suitable for use in coatings for textiles and paper.
