Dimethylsilicone oil is widely used as a lubricant in various mechanical and industrial applications due to its excellent thermal stability and low viscosity. It is commonly applied in high-temperature environments, such as in automotive engines and machinery, to reduce friction and wear. In the cosmetic and personal care industry, it is utilized as a key ingredient in skincare and haircare products, providing a smooth, silky texture and enhancing spreadability. Additionally, it serves as a defoaming agent in industrial processes, including food production and wastewater treatment, to control foam formation. Its water-repellent properties make it suitable for use in waterproofing coatings for textiles, electronics, and construction materials. In the medical field, it is employed in certain formulations for topical treatments and as a lubricant for medical devices.
