Tergitol 4-Nonylphenol branched ethoxylated is widely used as a nonionic surfactant in various industrial and household applications. It is commonly employed in the formulation of cleaning products, including detergents and degreasers, due to its excellent emulsifying and wetting properties. In industrial settings, it is utilized in metal cleaning, textile processing, and as a stabilizer in polymerization processes. Additionally, it serves as an effective dispersing agent in agricultural chemicals, aiding in the even distribution of pesticides and herbicides. Its ability to reduce surface tension makes it valuable in emulsion formulations for coatings and paints. In the oil and gas industry, it is used in drilling fluids and enhanced oil recovery processes. However, its use is being increasingly scrutinized and regulated due to environmental and health concerns related to its biodegradation products.
