1-Octadecanol is widely used as an emulsifier and thickening agent in cosmetics and personal care products, such as lotions, creams, and hair care formulations, to improve texture and stability. It acts as a lubricant and emollient, providing a smooth feel to the skin and helping to retain moisture. In the pharmaceutical industry, it is utilized as a coating agent for tablets and capsules to control drug release and enhance stability. Additionally, it serves as a raw material in the production of surfactants, plasticizers, and lubricants in industrial applications. Its ability to form stable gels makes it useful in candle manufacturing, where it improves the burning properties and consistency of the wax.
