Dimethylsilicone oil is widely used as a lubricant in various industries due to its thermal stability and low viscosity. It is commonly applied in machinery, automotive components, and precision instruments to reduce friction and wear. In the cosmetics and personal care industry, it serves as a key ingredient in skincare and haircare products, providing a smooth, non-greasy texture and enhancing spreadability. It is also utilized in medical devices and pharmaceuticals as a coating or lubricant for syringes, catheters, and other equipment. Additionally, it acts as a defoaming agent in industrial processes, such as food production and wastewater treatment, to control foam formation. Its water-repellent properties make it suitable for use in waterproofing applications for textiles and electronics.
