Mineral oils are clear, odorless liquids derived from refining crude oil. They are composed mainly of saturated hydrocarbons and are commonly used in various applications, including cosmetics, pharmaceuticals, and industrial lubricants. Due to their stability and low reactivity, mineral oils are often preferred for products that require a long shelf life. In the cosmetic industry, mineral oils serve as moisturizers and emollients, helping to soften and protect the skin. However, some people may prefer alternatives like plant oils due to concerns about potential skin irritation or environmental impact. Overall, mineral oils play a significant role in many everyday products.
