Sodium nonylphenoxide is a typical anionic surfactant derived from nonylphenol, with excellent surface activity, emulsifying, dispersing, wetting and solubilizing properties. It can effectively reduce the surface tension of water-based systems, make oil and water phases form stable emulsions, and improve the dispersion and penetration ability of substances in the system.

It has good chemical stability and can maintain stable performance in a certain range of acidic and alkaline environments, and also has certain resistance to hard water. It is widely used as an emulsifier and dispersant in the industrial production of pesticides, coatings and inks, helping to mix oil-soluble raw materials with water-based carriers uniformly and improve the stability and application effect of products.
