Tergitol 4-Nonylphenol branched ethoxylated is widely used as a nonionic surfactant in industrial and household cleaning products. Its ability to reduce surface tension makes it effective in detergents, emulsifiers, and wetting agents. In industrial applications, it is utilized in metal cleaning, textile processing, and agricultural formulations. It also finds use in emulsion polymerization, where it stabilizes polymer particles during the production of paints, coatings, and adhesives. Additionally, it is employed in the formulation of personal care products, such as shampoos and lotions, due to its emulsifying and solubilizing properties. However, its use is regulated in some regions due to environmental and health concerns related to nonylphenol ethoxylates.
