Mineral oil is a clear, odorless, and colorless liquid derived from refining crude oil. It is a broad category of petroleum products, and its primary components are alkanes and cycloalkanes. It’s used in a variety of applications across different industries due to its lubricating and non-reactive properties.

2. Industrial Applications: It serves as a lubricant for machinery, a hydraulic fluid, and a coolant in various industrial processes. Its stability and non-reactivity make it ideal for these uses.

3. Household Uses: Mineral oil is used in products like cutting boards, wooden utensils, and furniture polish. It helps to condition and protect wood.

4. Electrical Insulation: It is used in transformers and other electrical equipment to insulate and cool components.
