4-Octylphenol-ethoxylate (mono-, di-, tri-) is widely used as a nonionic surfactant in various industrial and household applications. It is commonly employed in the formulation of detergents and cleaning products due to its ability to reduce surface tension and enhance the removal of dirt and grease. In the textile industry, it serves as a wetting and dispersing agent, improving the processing of fabrics and fibers. Additionally, it is utilized in agricultural chemicals as an emulsifier, aiding in the even distribution of pesticides and herbicides. Its compatibility with other chemicals makes it a versatile ingredient in personal care products, such as shampoos and cosmetics, where it functions as a stabilizer and emulsifier. In industrial settings, it is also used in metal cleaning and degreasing processes, ensuring efficient removal of oils and contaminants.
